Seamless integration
with GitHub
Join more than 1 million developers already using CircleCI’s integration
with GitHub
to optimize your build and test automation.
If you are a GitHub user and not ready for private projects, choose public repos. We ask for read/write access to make your experience seamless on CircleCI. By signing up, you are agreeing to our SaaS Agreement and Privacy Policy.


No plugins to install
CircleCI mirrors your GitHub team permissions and privileges, which means you can start building right away.

View your test results in GitHub
CircleCI automatically runs your build and test processes whenever you commit code, and then displays the build status in your GitHub branch.

Choose the environment you need
Create a config.yml in your project’s root directory and CircleCI will read it each time it runs a build.

We are where you are
Communicate build statuses with the tools your teams already uses like Slack, IRC, and email.
