How developers work
Support your workflow with lightweight tools and features. Then work how you work best—we’ll follow your lead.
Code review
Seamless code review
Code review is the surest path to better code, and it’s fundamental to how GitHub works. Built-in review tools make code review an essential part of your team’s process.
Propose changes
Better code starts with a Pull Request, a living conversation about changes where you can talk through ideas, assign tasks, discuss details, and conduct reviews.
See the difference
Reviews happen faster when you know exactly what’s changed. Diffs compare versions of your source code side by side, highlighting the parts that are new, edited, or deleted.
Give clear feedback
Your teammates shouldn’t have to think too hard about what a thumbs up emoji means. Specify whether your comments are required changes or just a few suggestions.
Request reviews
If you’re on the other side of a review, you can request reviews from your peers to get the exact feedback you need.
Comment in context
Discussions happen in comment threads, right within your code. Bundle comments into one review, or reply to someone else’s inline to start a conversation.
Protect branches
Only merge the highest quality code. You can configure repositories to require status checks, reducing both human error and administrative overhead.

Project management
Manage your ideas
Coordinate early, stay aligned, and get more done with GitHub’s project management tools.

See your project’s big picture
See everything happening in your project and choose where to focus your team’s efforts with Projects, task boards that live right where they belong: close to your code.
Cards
Reference every Issue and Pull Request in a card, a drag-and-droppable snapshot of the work your teams do in your repository.
Notes
Capture early ideas that come up as part of your standup or team sync, without polluting your issues.
Track and assign tasks
Issues help you identify, assign, and keep track of tasks within your team. You can open an Issue to track a bug, discuss an idea with an @mention, or start distributing work.
Milestones
Add a milestone to your Issue or Pull Request to organize and track progress on groups of issues or pull requests in a repository.
Assignees
Assign an Issue or a Pull Request to one or more teammates to make it clear who is doing what work.
Integrations
The right tools for the job
Browse and buy apps from GitHub Marketplace with your GitHub account. Find the tools you like or discover new favorites—then start using them in minutes.

Discover new tools
A well-timed app can complement your workflow and help your team accomplish more. Hundreds of tools work with GitHub to help your team communicate, automate work, and have a better day.
Extend GitHub
Sometimes only a custom tool will do. Create your own tools with greater access to data than ever before using the GitHub GraphQL API—the same API we use to build GitHub.
Made for you, by us
We’re building developer tools, too. We hope they help you work on projects of any size and share ideas with your friends and coworkers. Try them out or help us build them.
Team management
The human side of software
Building software is as much about managing teams and communities as it is about code. Whether you’re on a team of two or two thousand, we’ve got the support your people need.
Manage and grow teams
Help people get organized with GitHub teams, level up access with administrative roles, and fine tune your permissions with nested teams.
Keep conversations on topic
Moderation tools, like issue and pull request locking, help your team stay focused on code. And if you maintain an open source project, user blocking reduces noises and ensures conversations are productive.
Set community guidelines
Set roles and expectations without starting from scratch. Customize common codes of conduct to create the perfect one for your project. Then choose a pre-written license right from your repository.
Open source guides
Our guides cover the fundamentals of open source maintenance—from starting a new project to introducing innersource to getting paid for all your hard work. Learn more about open source at GitHub or get ready to launch a project of your own.
Documentation
Documentation alongside your code
Quality documentation is a hallmark of any healthy software project. On GitHub, you can create well-maintained docs and make sure they receive the high level of care they deserve.
GitHub Pages
Host your documentation directly from your repositories with GitHub Pages. Use Jekyll as a static site generator and publish your Pages from the /docs folder on your master branch.
Wikis
Write documentation using the power of version control. Each wiki is its own repository, so every change is versioned and comparable. A text editor lets you easily add your docs in the text formatting language of your choice, like Textile or GitHub Flavored Markdown.
Say "Hello, world"
In need of a site for your project? You can also host static sites to promote a project or portfolio with GitHub Pages.
Code hosting
All your code in one place
GitHub is one of the largest code hosts in the world with over 100 million* projects. Private, public, or open source, all repositories are equipped with tools to help you host, version, and release code.
Host all your code
Repositories help you keep code in one place, even if you use SVN or work with large files using Git LFS.
With unlimited private repositories for individuals and teams, you can create or import as many projects as you’d like.
Make changes confidently
Make changes to your code in precise commits so you can quickly search every commit message in your revision history to find a change.
Use the blame view to trace changes and discover how your file, and your code base, has evolved.
Package and release code
When you’re ready to share, you can package your changes from a recently closed milestone or finished project into a new release.
Draft and publish release notes, publish pre-release versions, attached files, and link directly to the latest download.
Flexible hosting plans
Keep all of your code in one place, wherever you need to host it. Get the same experience whether you’re hosting GitHub in the cloud, on your servers, or on AWS or Azure.
