When building a web application, choosing the right UI library can save a lot of time. Instead of building every button, dialog, dropdown, and form from scratch, you can use ready-made components.
If you are working with SolidJS, there are several UI libraries worth exploring. Some focus on accessibility and customization, while others help you build a complete interface faster.
In this article, we will explore five SolidJS UI libraries: Kobalte, Ark UI, RockSolid, Flowbite, and Corvu. We will look at what makes each library useful, along with its pros and cons.
1. Kobalte
Website: kobalte.dev
Kobalte is an accessible UI toolkit built specifically for SolidJS. It provides reusable, unstyled components that you can use to build your own design system.
It includes components such as dialogs, popovers, dropdown menus, tooltips, checkboxes, and more.
The main idea behind Kobalte is simple: it handles much of the complex behavior, while you decide how the components should look.
Why choose Kobalte?
Kobalte is a great option when you want accessible components without being forced to follow a particular design.
For example, if you are building a dashboard with custom colors, spacing, and typography, Kobalte gives you the behavior you need while leaving the visual design in your hands.
Pros
- Accessibility: Supports keyboard navigation, focus management, and ARIA attributes.
- Full styling control: Components come without predefined visual styles.
- SolidJS focused: Designed specifically for the SolidJS ecosystem.
- Composable: You can combine component parts and customize their behavior.
Cons
- More styling work: You need to write your own CSS or use a styling framework.
- Takes some learning: Understanding the component structure may take time at first.
- Not ready-made visually: You will not get a polished interface immediately after installation.
Best for: Developers who want accessible components and complete control over their application's design.
2. Ark UI
Website: ark-ui.com
Ark UI is a headless component library that supports multiple frameworks, including SolidJS, React, Vue, and Svelte.
It provides accessible components for building interactive interfaces. Examples include dialogs, accordions, menus, sliders, tabs, and date pickers.
Like Kobalte, Ark UI does not force a default visual design on your application. Instead, it provides the behavior and structure needed to build your own components.
Why choose Ark UI?
Ark UI is worth considering if you want to build a custom design system that could work across different frontend frameworks.
For example, a team working with both SolidJS and React may find it useful to have a similar component API across projects.
It is also a good option when accessibility and complex interactions are important.
Pros
- Multi-framework support: Works with SolidJS and several other popular frameworks.
- Accessibility built in: Helps handle keyboard interactions and accessible component behavior.
- Highly customizable: You can style components to match your design.
- Handles complex interactions: State-machine-based behavior helps manage different UI states.
Cons
- Requires custom styling: You need to build the visual design yourself.
- Can feel complex: Some components have multiple parts and configuration options.
- Framework differences matter: You must use the SolidJS version and its corresponding documentation in a SolidJS project.
Best for: Developers who need accessible, customizable components and want a similar UI development approach across multiple frameworks.
3. RockSolid
Website: rocksolidjs.com
RockSolid is an emerging UI component library for SolidJS that focuses on reusable components and styling with Tailwind CSS.
It aims to help developers build modern interfaces using reusable components and theme settings.
It also focuses on accessibility and supports both LTR (left-to-right) and RTL (right-to-left) layouts, making it useful for applications that support multiple languages and writing directions.
Why choose RockSolid?
RockSolid is a good option if you want to build interfaces quickly without giving up control over the design.
For example, you can start with an existing button, card, or other UI component and customize its appearance to fit your application's theme.
This approach can save time compared to building every component and its styles from scratch.
Pros
- Ready-made styling: Helps you build an interface without styling every component from scratch.
- Accessibility: Provides accessibility-focused UI components.
- Consistent UI: Helps maintain a consistent look across your application.
- Theme customization: Offers theme settings for creating a consistent look.
- TypeScript support: Useful for type-safe component development.
- Dark mode support: Helps when building applications with light and dark themes.
Cons
- Learning curve: You may need time to understand its components and styling options.
- Custom design work: Some designs may require additional styling.
- Tailwind dependency: You need to be comfortable with Tailwind CSS and its setup.
Best for: Developers who want ready-made SolidJS components with the flexibility to customize their styling.
4. Corvu
Website: corvu.dev
Corvu is a collection of unstyled, accessible, and customizable UI primitives built specifically for SolidJS.
It includes components such as dialogs, accordions, drawers, popovers, tooltips, calendars, and resizable panels.
Corvu focuses on giving developers the building blocks needed to create interactive interfaces without forcing them to use a particular visual style.
It also supports server-side rendering (SSR), making it useful for applications that render content on the server.
Why choose Corvu?
Corvu is a strong option if you want components that fit naturally into SolidJS and give you control over both styling and behavior.
For example, if you are building a custom dashboard with animated drawers, dialogs, or resizable layouts, Corvu provides useful primitives without requiring you to build everything from scratch.
Pros
- Accessible components: Supports accessibility patterns for interactive elements.
- Customizable: You can control the appearance and adapt components to your design.
- Useful component selection: Includes dialogs, drawers, calendars, and other interactive elements.
- SSR support: Can be used in server-rendered applications.
Cons
- Requires styling: Components are unstyled, so you need to create your own design.
- Requires understanding component behavior: More advanced interactions may need additional setup.
- Not a complete visual design system: You will need to establish your own colors, spacing, typography, and component styles.
Best for: SolidJS developers who want lightweight, accessible building blocks for custom interactive interfaces.
5. Flowbite
Website: flowbite.com
Flowbite is a UI component library built around Tailwind CSS. It provides reusable interface elements such as buttons, navbars, dropdowns, modals, accordions, and date pickers.
Flowbite is especially useful if you want to build a website quickly using ready-made components and Tailwind utility classes.
However, there is an important detail for SolidJS developers: Flowbite's core component library is not a native SolidJS component library in the same way Kobalte and Rocksolid are. Its official SolidJS guide shows how to use Flowbite's CSS and JavaScript-based components with a SolidJS project.
You should check each component's compatibility with SolidJS before relying on it for interactive features.
Why choose Flowbite?
Flowbite is a good option if you already use Tailwind CSS and want to build common website interfaces quickly.
For example, you can use its component styles to create a landing page, navigation bar, or marketing website without designing every element yourself.
Pros
- Ready-made components: Saves time when building common UI elements.
- Tailwind CSS based: Works naturally with Tailwind styling workflows.
- Useful for websites: Includes components for navigation, forms, modals, and more.
- Faster UI development: Reduces the need to create common styles from scratch.
- Official SolidJS guide: Provides a starting point for integrating Flowbite with SolidJS.
Cons
- Not fully native to SolidJS: Interactive components may need extra integration work.
- JavaScript compatibility: You may need to handle component initialization and lifecycle behavior carefully.
- Tailwind CSS required: You need to configure Tailwind CSS correctly.
- Component behavior needs testing: Check accessibility, keyboard support, and state synchronization in your SolidJS application.
Best for: Developers who already use Tailwind CSS and want ready-made styles for websites, especially when they are comfortable handling integration details.
