How developers work
Support your workflow with lightweight tools and features. Then work how you work best—we'll follow your lead.
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.
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.
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.
Only merge the highest quality code. You can configure repositories to require status checks, reducing both human error and administrative overhead.
Share your work
Want to use GitHub to work on a side project? See how to get started and make your next idea happen.
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.
Reference every Issue and Pull Request in a card, a drag-and-droppable snapshot of the work your teams do in your repository.
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.
Add a milestone to your Issue or Pull Request to organize and track progress on groups of issues or pull requests in a repository.
Assign an Issue or a Pull Request to one or more teammates to make it clear who is doing what work.
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.
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.
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.
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.
