How developers work

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

Plan and manage projects from your repositories. Product managers, project maintainers, and engineers can coordinate early, stay aligned, and get more done.

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.

Community management

The human side of software

Behind every project is a group of living, breathing humans, which makes building software as much about managing people as it is about code. Whether you’re on a team of two or two thousand, we can help support your people.

Manage and grow teams

Help people get organized with GitHub Teams, level up access with administrative and user roles, or grow your project with repository invitations.

Keep conversations on topic

It’s easy to get off topic when lots of people are involved. Moderation tools, like Pull Request and Issue Locking, help your team stay focused on code. And if you maintain an open source project, user blocking ensures your community stays healthy.

See who’s behind the project

Show what’s behind the green squares on your GitHub profile with your public activity and proudest moments. Pin your favorite projects to your profile or browse others’ timelines to see what projects they’ve shaped.

Code hosting

All your code in one place

GitHub is one of the largest code hosts in the world with over 52 million projects. Private, public, or open source, all repositories are equipped with tools to help you host, version, and release code.
