Best Chrome Extensions to boost GitHub

Today, most of us spend most of our time on web browsers rather than desktop apps. Thus, to improvise the browsing experience and optimize overall productivity, Google Chrome extensions have come to the rescue.

Chrome extensions are software packages that introduce additional functionalities to your Chrome browser. They enable you to personalize your web-browsing experience by adding features with a single mouse click. They assist you in making effective use of the internet by allowing you to focus on your work, save money, become more efficient, and keep your personal information safe.

These packages let you execute specific tasks in the Chrome browser, such as taking a snapshot of a webpage or studying keyword volume. Commonly, HTML, CSS, and JavaScript are used by developers to create these extensions.

Here are a few examples of the kind of functionality that a Google Chrome extension can add to Chrome:

  • Blocking advertisements from being displayed
  • Optimize Chrome's memory usage so that it runs more effectively
  • Creating to-do lists or taking notes with Chrome
  • Managing passwords
  • Facilitating the copying of text from a website
  • Securing your web browser while protecting your privacy

As you can see, these extensions provide a wide range of additional functionality to help you execute activities more efficiently or get more out of the websites you frequently use. Since GitHub is one of the most comprehensive platforms for developers, this roundup will cover some of the best and most useful GitHub Chrome extensions for developers and designers to employ.

Awesome Autocomplete for GitHub

Add instant search capabilities to GitHub's search bar.

Awesome Autocomplete for GitHub, as the name suggests, is a discreet and straightforward Chrome extension that helps to enhance GitHub's search bar, letting you search through repositories and people from the massive bulk of GitHub's database with speed faster than ever.

This extension provides a developer-friendly database search SaaS API built and powered by Algolia that allows any website or mobile application to give its end-users a quick and relevant search (auto-completion & recommendation) on the following:

  • top public repositories
  • most recent active users

You may use this extension to search via your private repositories; however, the default configuration disables Algolia; thus, it is done in your browser using vanilla JS search. To utilize Algolia search, which gives typo-tolerant and relevance-improved results, you must connect this app to GitHub using GitHub OAuth. Furthermore, you can search through issues once you have connected them with GitHub.

Awesome Autocomplete for GitHub

This extension continually pulls data about active repositories and users from the GitHub Archive dataset and saves it in two separate Algolia indices - 'users' and 'repositories.' When a user starts a search, the results are received using Algolia's JavaScript API client and presented on the UI which leverages Twitter's typeahead.js library to display the auto-completion menu.

Version 1.6.0 can also find GitHub repositories directly from the address bar by typing aa<space>. However, the address bar auto-completion feature does not work on Safari.

Next-level code navigation for GitHub.

CodeWing is a Chrome extension that helps you with next-level code navigation in repositories containing code in Python, Java, and Go on GitHub. The browser extension is entirely open-source, with the complete source code available on GitHub; however, the server is a closed source. Also, it completely ignores the private repositories and only sends code locations to the server, thus, keeping them safe and secure.

Primary features of this extension include:

  • Hover Docs: Hover your cursor over any variable, function, or class to see its documentation in a syntax-highlighted tooltip.

Hover Docs

  • Jump to the variable definition: Clicking on any variable, function, or class lets you jump to its definition within a file or a pull request. The best thing here is that CodeWing works on pull requests, file views, diff views, and blame views, too, rather than GitHub, which only works on file views for branch tips.

  • Understands more language constructs: Only functions are recognized by GitHub, whereas CodeWing also detects local variables, functions, classes, fields, parameters, and so on.

Links together, what belongs together.

OctoLinker is a GitHub browser extension that converts language-specific statements such as include, require, or import into links. It is packed with the capability to connect dependencies defined in files such as package.json, composer.json, Gemfile, or requirements.txt to their corresponding GitHub project page.

It reads the source code you're presently viewing in the browser or, in some situations, over the GitHub API; thus, there will never be any source code transferred to a server, and the source code will always remain in your browser only.


It helps you effectively find a file within your code by calling a plugin based on the file type, which then executes a regular expression on the source code to detect import statements. Meanwhile, it uses GitHub tree API in your browser to resolve related file references. Similarly, it uses the OctoLinker API to resolve the external dependencies using the dependency's name and the registry type.

Furthermore, it links to the official API docs to facilitate faster development. Moreover, OctoLinker will inject links if it detects a file type from a code snippet in a Markdown file, Issue, or Pull Request or comment, thus, helping in faster code reviews.

OctoLinker helps you avail all of these functionalities for the public as well as private repositories, although it would require a GitHub access token to access your private repositories. No worries, though—the token isn't sent to the server; instead, it remains in your browser, ensuring a safe and secure browsing experience.

Add code intelligence to GitHub

Sourcegraph is a free and open-source Chrome extension that adds code navigation and intelligence to GitHub, GitHub Enterprise, GitLab, Bitbucket Server, and Phabricator. It supports over 20 programming languages and includes hovering with documentation and type information, variable or function definition, and locating imports and dependencies.

Sourcegraph services

It also supports interfaces with third-party services such as Codecov coverage overlays, open-in-editor buttons, and many others. It also includes extensive browser extension documentation to help you get the most out of it.


The self-hosted deployment is free for up to 10 users and supports additional code hosts. It provides a lot of team-oriented functionalities and even a free 30-day trial of enterprise-only features to help you build, write, reference, fix and deploy code faster. Meanwhile, Sourcegraph Cloud allows individuals to access their index of over 1 million open-source repositories easily but does not support enterprise features such as user management, SAML integration, and batch changes.

Lovely forks

Show notable forks of GitHub repositories under their names.

Lovely forks is a chrome add-on built to bring your notice to notable forks (i.e., forks with the most stars) for GitHub projects. It helps to keep track of the community-appreciated fork by adding a subscription under the repository's name on the Github page of all projects with a link to that fork.

Lovely Forks

This could be extremely useful in cases where the original repositories are abandoned due to inactivity from the original author; however, the development continues on a fork. In these cases, this extension would help newcomers quickly discover such forks without wasting time on old, buggy versions of the projects.

I wanted to also add "GitHub Repository Size" extension to this great list. I use it to get an idea of the size of a repo before i go ahead and clone it onto my machine.

First recomandation is an archived project without any updates in more than two years. I guess that posts needs QA too, not only code.
