Secure development

Securing software, together

We all play a role in securing the world’s code—developers, maintainers, researchers, and security teams. On GitHub, development teams everywhere can work together to secure the world’s software supply chain, from fork to finish.

Get alerts about vulnerabilities in your code

We continuously scan security advisories for popular languages, and send Dependabot alerts to maintainers of affected repositories with details so they can remediate risks.

Automatically update vulnerabilities

We monitor your project dependencies and automatically open pull requests to update dependencies to the minimum version that resolves known vulnerabilities.

Stay on top of CVEs

Stay up to date with the latest Common Vulnerabilities and Exposures (CVEs), and learn how they affect you with the GitHub Advisory Database.

Find vulnerabilities that other tools miss

CodeQL is the industry’s leading semantic code analysis engine. Our revolutionary approach treats code as data to identify security vulnerabilities faster.

Eliminate variants

Never make the same mistake twice. Proactive vulnerability scanning prevents vulnerabilities from ever reaching production.

Keep your tokens safe

Accidentally committed a token to a public repository? We’ve got you. With support for 20 service providers we’ll take steps to keep you safe.

Protect your users

We provide the infrastructure security researchers and open source maintainers need to responsibly disclose security vulnerabilities.

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.

Hosting

All your code and documentation in one place

There are hundreds of millions of private, public, and open source repositories hosted on GitHub. Every repository is equipped with tools to help you host, version, and release code and documentation.

Code where you collaborate

Repositories keep code in one place and help your teams collaborate with the tools they love, even if you 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.

Compare features of our different GitHub subscriptions.

Documentation alongside your code

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.

Learn more about publishing documentation on GitHub Pages or wikis.

Project management

Manage your ideas

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

Learn about project management →

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.

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.
