In today's era of high technologies, distributed teams, and remote work, it has become essential for organizations to invest in project management applications. Choosing the right features to equip your project management app is crucial for your team's productivity and budget. According to the Capterra user rating data, project planning and scheduling are the key features of project management software. The best way to make this feature a part of your project is to use a Gantt chart. Gantt charts give you full control over the project workflow and resource allocation.
In this article, we will consider popular commercial and open-source JavaScript Gantt components that will help you integrate a Gantt chart into your project management app much faster.
Commercial Gantt Components
First, let us look closely at paid-for Gantt options and highlight their main characteristics. Businesses frequently prefer such products since they have rich feature sets, get regular updates and technical support, and can be used with various JavaScript frameworks (React, Angular, Vue.js) and back-end technologies.
DHTMLX Gantt
DHTMLX Gantt is a mature and developer-friendly JavaScript library for building Gantt chart interfaces suitable for a wide range of scenarios, from standard project planning apps to large-scale enterprise solutions. It combines an extensive set of built-in features that can be flexibly configured to meet various project management needs.
For common use cases, you can create projects with different types of tasks (regular and unscheduled), set various types of task dependencies, sort and filter data, add project summaries with rollup tasks, and make changes on the fly with drag-and-drop, keyboard navigation, and inline editing.
If the achievement of your objectives requires more sophisticated tools, DHTMLX Gantt has a lot to offer to bring your project management experience to a new level. Here you can enjoy numerous advanced features such as auto-scheduling and critical path powered by the built-in scheduling engine, flexible time formatting, split tasks, task constraints, multiple charts on one page, and much more. When these sophisticated features are combined with high workloads (30,000 - 50,000 tasks), typical for large ERP or CRM systems, DHTMLX Gantt maintains high responsiveness and rendering efficiency with the help of dynamic loading, smart rendering, and other performance optimizations.
DHTMLX Gantt is especially good at handling project resources assigned to tasks on a full- or part-time basis. There are two layout views showing resource workload and allocation – resource load diagram and histogram. These views get in sync with the main Gantt chart, and thus it is easy to balance the workload. You can also group tasks by resources, create working calendars for different resources (usually referring to employees), and merge them into one.
The comprehensive API provides an arsenal of methods, properties, events, and templates to customize any Gantt chart element as desired. You are free to add new timeline items (baselines, deadlines), custom tasks and time scales, and custom content in timeline cells or on top of Gantt. The UI is flexible and personalizable thanks to the availability of 8 predefined themes (skins), including high-contrast ones, localization (52 locales), full accessibility support, and RTL mode.
The DHTMLX team also offers useful add-ons to reinforce Gantt in your web apps. There are standalone export modules for safely exporting your charts to PDF or PNG format and converting Gantt data for use in popular software - MS Project and Primavera. A Node.js server module is indispensable for performing complex operations on the Gantt chart, integrating it with third-party systems, and providing a flawless user experience for teams working simultaneously on multiple devices.
On top of that, DHTMLX Gantt can be easily integrated with other DHTMLX components such as Scheduler, Kanban, and To Do List for building a versatile web solution for your business. Also, there is an easy way to complement the Gantt component with a PERT chart built with DHTMLX Diagram.
Detailed developer guides and a large collection of live samples (850+) allow you to quickly learn the essentials of working with the Gantt chart and make the most of its capabilities.
DHTMLX Gantt has a flexible licensing model, which allows adjusting the license to the size of your development team and your requirements. Thus, it is perfect for companies of any size, from small startups and medium-sized projects to large corporations.

Bryntum Gantt
Bryntum Gantt is a JavaScript version of Bryntum’s Gantt for Ext JS, introduced back in 2019. This product has some noteworthy peculiarities related to managing project data (tasks, resources, dependencies, etc.) on the backend and the presentation of this data in the UI.
Under the hood, it uses an in-house-produced scheduling engine based on the company’s other technology called ChronoGraph for working on projects of different scales. The Gantt engine supports automatic scheduling, backward scheduling, task constraints, 4 scheduling modes, calendars (for projects, events, and resources), recurrent and fixed time intervals for calendars. The engine is also responsible for effort and duration calculations, scheduling conflict resolution, and resource distribution.
The UI part of the Gantt is based on the Bryntum Grid and inherits most of its features such as filtering, sorting, column resizing, and summarizing. The Gantt structure may include multiple, individually scrollable grid sections (on the right of the timeline). For instance, you can create new sections with inactive tasks or resources and then add these items to the project with drag-and-drop. Bryntum Gantt also allows using baselines, labels, time range indicators, and progress lines in the Gantt timeline to make it more informative.
There is a built-in editor with programmatic validation of any editing actions. The editor comes with tabs for managing task parameters, attached files, resources, dependencies, and other settings, and can be extended with custom fields and controls. Animated redraws help users to keep track of changes that occur on the timeline after edits.
If necessary, you can override almost any part of the codebase and adjust Gantt elements to your needs. This component is shipped with five built-in themes that allow specifying the general appearance of the Gantt chart. Project data can be exported to Microsoft Excel, Microsoft Project, PDF, PNG, and ICS formats.
Since the Gantt component shares the same technical foundations (architecture, data structures, API) with other timeline-based Bryntum products like Scheduler and Task Board, it becomes easier to bring these functionalities together in a single app. In addition, Bryntum provides a collection of basic UI widgets (checkbox, colorpicker, menu, etc.) that can be added to the Gantt chart without much trouble. There is also an integration demo of Bryntum Gantt + PERT Chart (built with JointJS).
To my mind, Bryntum Gantt can be considered for project management apps that demand built-in scheduling capabilities, smooth interactions, and robust tools for task management.
Useful resources: documentation, samples, blog, YouTube channel
Trial version: Bryntum Gantt
Price: from $940 (for internal and non-commercial use), commercial projects require a subscription-based OEM license - price on request.
Webix Gantt
Webix Gantt is a JavaScript widget included in the Webix UI Library. When integrated into a web project, this Gantt component allows creating tasks and subtasks, tracking their progress, assessing potential risks, and detecting bottlenecks in projects. The widget supports all the CRUD operations for handling project tasks.
You can flexibly configure the Gantt in accordance with your project requirements. If the basic feature set does not satisfy the needs of your project, you can add more advanced features. For instance, it is possible to expand the Gantt functionality with complex scales and zooming, baselines, marks on scales, division of tasks, critical path calculation, and more. Webix Gantt also provides instruments for working with project resources (Resource view) and tracking their workload (Resource diagram).
The widget is based on the Webix Jet micro-framework designed to speed up the development of Webix-based apps. With Webix Jet, the Gantt interface is divided into numerous stand-alone Webix components (views). Thus, you can modify, add, or even remove any part of the UI.
This Gantt widget has a decent feature set and provides a compact mode for a convenient scheduling experience on devices with smaller screens. However, there are few licensing options for buying Webix Gantt without additional tools.

Syncfusion Gantt
Syncfusion Gantt is one of the numerous JavaScript controls included in the Essential JS 2 library and carries all of its general features. For instance, you can benefit from a modular architecture, touch support, multiple built-in themes, seamless data binding, and other useful features. For those whose only goal is to visualize project workflows, Syncfusion offers a special Gantt SDK edition that includes only Gantt and Kanban controls.
The Gantt control is equipped with a set of features specifically dedicated to planning, scheduling, and monitoring one or more projects and the resources involved within a single Gantt chart. The Gantt interface allows presenting tasks with their dependencies and manipulating them in different timeline modes (hour, week, month, and year). Dependency validation helps prevent conflicting changes in dependency relations during task editing and other data operations.
The timeline may have additional details (working days and holidays, baselines, event markers, tooltips, critical path), making it easier to understand and analyze data. Support for time zones helps coordinate task schedules for users in different regions who access the Gantt chart.
There are many options for specifying the behavior of the grid panel. For instance, it is possible to pin a column (on the left, on the right, or on both sides), use column menus, and span columns and rows to make the layout more readable when dealing with complex project structures. If needed, the Gantt content can be exported to PDF and Excel formats.
Using different template options, you can create custom headers, taskbars, cell contents, editors, and other items. The online Theme Studio tool allows you to create custom Gantt appearances using built-in themes without any code modifications.
Syncfusion Gantt is a natural choice for teams already familiar with the Syncfusion ecosystem and planning to use Gantt alongside other UI controls in cross-platform apps.

AnyGantt
AnyGantt is a JavaScript-based tool provided by the AnyChart company for embedding informative Gantt charts into web apps. Using this solution, you can create two types of Gantt chart views - Project and Resource. The first Gantt type is intended for visualizing scheduled project workflows, while the second one displays operational assets (workers, equipment, etc.) used for achieving certain goals over periods of time.
AnyGantt focuses more on animation-powered visualizations of project workflows, so you should not expect any complex scheduling features. At the same time, it involves standard Gantt features like dependencies, milestones, task hierarchies, baselines, and progress indicators. AnyGantt also offers a variety of formatting options for text-based elements and settings for date and time formats. The Live Edit mode helps to introduce changes in the Gantt chart on the go with drag-and-drop. A flexible design system helps define the appearance of Gantt elements in the desired way.
AnyGantt supports asynchronous rendering for convenient working with data-intensive charts. This Gantt component uses the GraphicsJS library for customizing timeline elements. This graphics library helps replace default items with custom ones in project and resource charts. It is possible to export charts to images (SVG, PNG, JPG), PDF, or data files (CSV, Excel).
AnyGantt is a viable option for dashboards, reporting tools, and BI apps that demand plain Gantt chart views alongside other charts for in-depth data analysis.

Trial version: AnyGantt
**Price: from $799 for internal apps, prices for enterprise and OEM licenses are available upon request.
Kendo UI jQuery Gantt
The Kendo UI for jQuery library by Telerik provides a variety of UI components for implementing various functionalities on the client side, including Gantt charts. For displaying all necessary project planning info, the layout of the jQuery Gantt chart consists of two standard views - GanttList and Timeline.
The GanttList view is an extended version of Kendo’s TreeList widget that inherits most of its capabilities and shows tasks, resources, owners, dates, and all other important data in a tabular form. If necessary, you can apply extra editing, filtering, expanding/collapsing, and visibility attributes to grid columns.
Using Gantt templates, it is possible to add new types of content in columns (e.g. images of task owners). The Timeline view serves to illustrate tasks with their duration and dependencies on different timescales (day, week, month). End-users can perform various operations on tasks such as rescheduling, deleting, editing, or changing dependencies between tasks. The component supports resource assignments and allows comparing planned task times vs. their actual execution time.
Being a part of the Kendo UI for jQuery library, this jQuery Gantt supports all of its basic features. You can take advantage of customizable stock themes, the DataSource library, exporting to PDF and Excel, and accessibility features.
Since this Gantt component cannot be obtained as a single-item tool, it can be a decent investment for teams that already use the Kendo UI library in their projects.

Trial version: Kendo UI for jQuery
Price: from $799 for the full package of Kendo UI components (the license is subscription-based)
Netronic Visual Scheduling Widget
The Visual Scheduling Widget (VSW) is a jQuery Gantt component with ESM and TypeScript support developed by Netronic to facilitate integrating a multifunctional scheduling chart into web applications. The user interface of this widget seems a bit old-fashioned and cumbersome, but it still offers solid capabilities for managing complex projects.
A timescale is an essential part of any Gantt chart that should be flexible and easy to use, therefore, the VSW widget allows changing this parameter dynamically. Resource management is another important feature of modern Gantt charts, and VSW gives the possibility to detect resource capacity conflicts by embedding a histogram right in chart rows. Resources can also be organized by skills for more specialized planning scenarios.
When complex projects are split into smaller and more manageable subprojects, VSW will continue visualizing dependencies in a clear manner. Much of the multi-level hierarchical data may be confusing for users, therefore VSW provides built-in animations for clarifying what’s happening on the screen. All unscheduled tasks and unassigned resources can be put together in the additional table (backlog) and simply dragged into the Gantt chart when needed.
The Visual Scheduling Widget (VSW) is particularly well suited to resource-oriented planning apps where capacity, availability, and allocation need to be presented alongside project schedules.

DayPilot Gantt Chart
DayPilot Pro for JavaScript is a JavaScript library comprising scheduling web components for business-oriented solutions. And as you probably guessed, it includes the Gantt component for visualizing different project management scenarios.
DayPilot Gantt supports essential features required for planning and managing project tasks: task types (regular, milestones, task groups), progress bars, bubble tooltips, context menus, etc. Users can move and resize tasks, add dependency links, reorder rows, interact with multiple tasks at the same time, and drag tasks to/from external UI elements. The Gantt chart performance is optimized to process workloads containing approximately 10,000 tasks with the progressive rendering of rows, tasks, and cells during scrolling. If needed, Gantt charts can be saved as images in SVG, PNG, and JPEG formats.
The Gantt component is customizable, allowing you to fine-tune Gantt elements to your liking. For instance, you can add custom time scales and columns with additional task data (duration, description, assigned resources). It also supports full CSS styling.
DayPilot offers two useful auxiliary tools for working with the library’s components. The CSS Theme Designer helps to build CSS themes for Gantt and other DayPilot components using the online WYSIWYG editor. The UI builder is used to quickly configure the Gantt UI and generate a downloadable project.
The Gantt component from DayPilot includes common features required for conveniently scheduling your projects. I think that it can be a good option for teams that need a Gantt chart as a part of a broader scheduling solution with other timeline-based views (Scheduler, Event Calendar, and Monthly Calendar) included in the DayPilot Pro for JavaScript library.
Useful resources: documentation, samples, tutorials, DayPilot knowledge base
Trial version: DayPilot Pro for JavaScript
Price: the Gantt component can be obtained only in a package with other DayPilot components: from $649 for internal use, from $1699 for OEM edition.
DevExtreme Gantt
DevExtreme Gantt is one of the latest additions to the collection of enterprise-specific UI widgets developed by DevExpress for building standard web and mobile apps. But it already has a standard set of features for managing project task flows and their dependencies over a certain period of time.
The DevExtreme Gantt component gives the possibility to avoid issues in task dependencies by defining your own validation rules. Filtering, sorting, and zooming features simplify the work with large Gantt charts. You can also display tasks in different time intervals (from hours to years) and highlight particular time spans in the timeline with strip lines. Moreover, it already allows making resource assignments. You are able to export the Gantt content to a PDF document.
This JavaScript widget also provides multiple customization capabilities. For example, you can play around with the general chart appearance (via settings or customizable themes), use templates for changing individual tasks, add custom controls to the toolbar, and adjust context menus.
DevExtreme Gantt is a practical choice for developers who already use DevExtreme in their projects and want to add project planning capabilities without introducing another UI component library.
Useful resources: documentation, samples, blog, YouTube channel
Trial version: DevExtreme
Price: from $899 (subscription for the full package of DevExtreme widgets)
Highcharts Gantt
Highcharts Gantt is a JavaScript Gantt library built on top of Highcharts, the popular charting library from Highsoft. It extends the Highcharts visualization model with features specifically designed for displaying and interacting with project tasks and dependencies along the timeline.
Created with the active participation and support of Highcharts clients, this component has many common Gantt features, such as dependency links, milestones, progress indicators, etc. are available by default and rendered. When dealing with big tasks, it is possible to split them into smaller subtasks and group resources and manipulate items in the timeline with simple drag-and-drop actions.
This Gantt component displays well on devices of any size and supports navigation with touch gestures, a mouse, and a keyboard.
When choosing Highcharts Gantt for your next project, you can benefit from the core features offered in all Highcharts products. Using the Highcharts export module, you can export charts to PNG, JPG, PDF, and SVG formats at the touch of a single button or print your Gantt chart right from the page. Gantt-based project visualizations can be enriched with other chart types included in the Highcharts library to provide more insights on the current project status.
Highcharts Gantt is a viable option for apps where Gantt charts are primarily used to visualize project timelines rather than provide a comprehensive project management UI. It is also a natural choice when the Gantt chart needs to be combined with other Highcharts visualizations.

Trial version: HighCharts Gantt
Price: from $439 (internal use), prices for OEM licenses are available on request
FusionCharts Gantt
FusionCharts is a well-known brand in the field of data visualization. Its flagship product FusionCharts Suite includes a wide variety of simple and complex charts. It also addresses the issue of creating a basic Gantt chart on the web page with the corresponding widget included in the FusionWidgets XT pack.
The Gantt widget does not support sophisticated features such as critical path calculation or auto-scheduling. But it still offers some useful things to help teams visually plan and track projects. The Gantt structure may include any number of additional columns for displaying extra parameters such as project resources. You can complement your Gantt chart with milestones, progress indicators for each task, trendlines to highlight specific dates ( "Today", "Holiday",etc.), tooltips, annotations, legends, and more. It is possible to ensure a consistent look of your chart using predefined themes and customize them if needed.
There are also other customization opportunities for this Gantt widget. The main Gantt elements (grid table, cells, dependency links, date formats) and additional timeline items (tooltips, milestones, legends, labels) can be adjusted to your requirements. The exporting feature will help you save your Gantt projects in JPG, PNG, SVG, and PDF formats.
This Gantt chart may be a nice option if you are building a dashboard or reporting interfaces displaying project data in a variety of ways. However, it lacks the major Gantt features necessary for full-fledged project management apps.

JSCharting Gantt
JSCharting is a JavaScript library that offers a way to add different types of charts to a web app, including Gantt charts via its JSGantt component. Since 2024, JSGantt has been available as a standalone product, so there is no need to invest in the whole JSCharting library if you need only Gantt.
This tool comes with a pack of standard features for visualizing and managing projects via a Gantt chart. It allows specifying task hierarchies, setting dependencies, adding milestones, and displaying task progress indicators. Moreover, it is possible to apply auto-scheduling and critical parth analysis to keep the project schedule on track. All project data can be loaded in the chart from JSON or the user’s database. Simple JavaScript settings allow configuring your Gantt chart as needed.
You can also count on a variety of general features available for all chart types included in JSCharting. The library is touch- and mobile-optimized, relies on SVG and HTML5 rendering, complies with the main accessibility standards, provides an official export server, supports various globalization and internationalization features, advanced visuals, etc.
Just like with Fusioncharts, JSGantt may be less suitable for a complex project management solution, but it is good enough for applications where Gantt charts are mainly used for project visualization.

GSTC
The gantt-schedule-timeline-calendar (GSTC) is a JavaScript component that can be used in business apps as a universal planning solution. It brings together four tools commonly used in companies all over the world for arranging their day-to-day activities. At the moment, we are primarily interested in the Gantt part of this product.
The Gantt interface can contain movable and resizable items, collapsible and expandable groups of tasks, multiple items in one row, sortable and searchable list columns, etc. One of the main strengths of GSTC is its elasticity i.e., almost any part of the component, from the DOM tree to logic, can be adjusted to your requirements with config, state, and custom plugins.
The HTML Gantt content is modifiable via templates and slots. The use of BEM-based CSS rules makes it easier to change the appearance of your Gantt chart. Moreover, it promises not to let you down with large datasets. Also, it should not be hard to add any third-party libraries.
GSTC does not provide any fancy Gantt features like the more specialized components reviewed in this list. At the same time, its flexible architecture makes it a decent instrument for building custom planning UIs, where Gantt can be complemented with scheduling, timeline, or calendar views.

Open Source Gantt Components
If you are starting a project with a limited budget or relatively basic Gantt requirements, one of the following open-source Gantt components may suit you.
DHTMLX Gantt Community Edition
To my knowledge, DHTMLX Gantt Community Edition is the only open-source Gantt library that brings together a solid feature set of the time-tested commercial product, detailed and well-organized documentation, a large collection of samples, and strong community support under permissive terms of the MIT license. In terms of functional capabilities, it can be a good choice for projects with various needs, from startups and internal tools to commercial project planning apps with standard requirements. Here, you get predefined task types, dependency relations, project summary, inline editing, built-in themes, and many other useful features. The component also follows the main performance and customization characteristics of the commercial (PRO) edition described in the previous section.
However, the Community Edition does not support PRO features like auto-scheduling, critical path, resource management, and advanced task operations. With this MIT-licensed Gantt, you also cannot count on access to wrappers for React, Vue, and Angular, extended exporting, and official tech support. But the good news is, when these things become a necessity for your project, there is a simple migration path from the Community Edition to the commercial PRO version.
Useful resources: GitHub repository, update path to PRO edition

Frappe Gantt
Frappe Gantt is another well-known Gantt option in the open-source landscape, but it focuses more on visually illustrating a project's tasks, schedule, and dependencies rather than adding any logic for accurate planning. After its debut as a core Gantt view in Frappe’s ERPNext platform, it then became a widespread free tool for project visualizations.
Frappe Gantt allows creating neat timelines with several view modes and populating them with the main Gantt items, including taskbars, dependency lines, progress indication, weekend/holiday marks, and tooltips. The simplicity of this tool can significantly reduce setup, maintenance, and customization effort. That is why teams that need lightweight project planning UIs in their apps prefer Frappe Gantt for their web projects.

Twproject Gantt
Twproject Gantt is an online JavaScript Gantt chart editor engineered by Open Lab as a stand-alone part of a more complex solution (Twproject) for visually planning and tracking projects.Gantt charts created in the editor can be complemented with essential Gantt features like dependency relations, milestones, and statuses that can be edited at any moment.
Moreover, the editor allows calculating a critical path to avoid bottlenecks and take care of project resources to ensure their balanced allocation. You can also use progress lines to see whether tasks are behind or right on schedule and compare the current state of the project with the initial plan using baselines. The Gantt chart can be printed and exported for sharing information offline.
Twproject Gantt can be especially convenient for teams that need to reproduce or extend the Gantt-based planning experience found in the Twproject platform.

Google Gantt Chart
Google Charts is a popular data visualization service with a rich selection of data visualization types, and a Gantt chart is one of them. This Gantt tool comes with a modest feature set for tackling common project management tasks. The Google Charts API comes with a range of configuration options, methods, and events for organizing your Gantt chart in the desired way. Charts are rendered in the browser using SVG technology.
You can set and edit the main parameters related to the timeframe of project tasks (start/end/duration). If any of these values are not specified by a user, they will be calculated automatically. The Gantt timeline can be displayed with or without dependency arrows. The Gantt chart built with Google displays relevant data on each task via tooltips. Depending on the Gantt configuration, the tooltip content may include the task timing, completion status (in %), project resources, and the presence of a given task on a critical path. Tasks dedicated to a particular area of the project can be combined into groups with resources. Styling settings allow depicting Gantt elements (tracks, dependency lines, critical path) in different colors.

Mermaid Gantt
MermaidJS is an open-source JavaScript diagramming and charting library that uses Markdown-inspired syntax to dynamically generate popular types of charts and diagrams such as flowcharts, UML diagrams, pie charts, and of course, Gantt charts. When implementing a Gantt chart with Mermaid, you can set the margins for rendering the chart, split its structure into different sections, and define a date format. It supports common features required for managing tasks such as tasks, durations, milestones, non-working days, markers, etc.
The Gantt appearance can be customized with themes and by defining CSS classes. There are 3 rendering options for your Gantt chart: SVG, PNG, or a Markdown link that can be inserted into docs. Even people without any coding background can create a Gantt chart and other diagrams using the Mermaid Live Editor.
Mermaid Gantt is particularly useful for documentation, technical specifications, and high-level project outlines, where a simple schedule needs to be maintained as text rather than managed through a full-featured Gantt view. Interestingly, GitHub added native support for Mermaid to help developers quickly generate diagrams in their open-source projects.
Mermaid.js now lives at mermaid.ai, a common space for the open-source library and platform built around it. The Mermaid.js library remains the foundation for generating diagrams from text, while the platform adds collaborative and AI-powered capabilities on top of it.

Summing Up
As you can see, there are plenty of commercial as well as open-source JavaScript Gantt libraries. And now the hardest part - choosing the right tool for your project. I just provided general information on the functional capabilities of Gantt libraries available out there. What to do next? You should certainly get acquainted with the technical part of all products by using useful resources added for each of them. While pricing and licensing may not be the ultimate driver in your decision, these are still important factors to consider, and I shared my thoughts on this matter for each commercial Gantt. And, of course, you cannot make the final decision without practical testing of tools that seem appealing to you.
