Do you support Bitbucket or GitLab?

Currently we support authentication with GitHub and Bitbucket. Please vote on relevant Feature Request if you want to show support for other version control systems.

What if I don’t want to include so many orgs when I am authorizing CircleCI?

You can change the org access using OAuth App Restrictions on GitHub, see the GitHub Help OAuth documentation for instructions.

I can’t give CircleCI the access to all my private repositories. What do I do?

GitHub has only recently added the fine-grained permissions options, and we are still working on supporting them.

In the meantime, the suggested workaround is to create an additional user on GitHub with a limited set of permissions and use that account to perform the builds on CircleCI.

To limit CircleCI from accessing your private repositories, select Public Repos Only from the Start with GitHub menu on the Sign Up page and on every subsequent login.

CircleCI does not yet support limiting access to only public Bitbucket repositories.

How does the GitHub Public Repos Only option work on CircleCI?

The Public Repos Only option uses scopes to specify access for the CircleCI app. CircleCI uses the repo scope by default which includes public and private repository access. CircleCI requests the public_repo scope for access to only public repos. See the GitHub Developer Documentation for more details about the GitHub scopes implementation and use.

Is there a way for me to limit access if I have already provided it?

Yes, limit access by logging out of the CircleCI app and logging back in with the Public Repos Only option. Note: Builds made when you had private access and followed private repos will appear, but any actions will fail because your current user would not have view or edit access.

If you created a separate account for this purpose previously, you can now sign up using the privileged account without providing access to private GitHub repositories by selecting Public Repos Only from the drop-down menu on the GitHub Start button.

I updated my email address on GitHub, and it does not show up on CircleCI

We refresh GitHub information once a day to stay within GitHub’s API limits, so check your profile page later – it will be right there.

Billing & Plans

Can I build more than one project if I only have one container?

Absolutely. In this case the builds will run one at a time, one after another.

How do I stop CircleCI from building a project?

If you get everyone who follows the project on CircleCI to unfollow it, we will automatically stop building it.


Can I get notifications to team chat applications?

CircleCI supports Slack, HipChat, Campfire, Flowdock and IRC notifications; you configure these notifications from your project’s Project Settings > Notifications page.

Can I send Slack / HipChat / IRC notifications for specific branches only?

There is experimental support for per branch chat notifications.

Discover CircleCI’s Public IP addresses

Currently CircleCI runs on multiple AWS Regions and utilizes many different servers to perform the builds. As such there isn’t a single IP, or even a small range of IPs, that could be used to help identify that an incoming request is from a build of your project.

Even if the IP range was known it would not be safe to trust the IP address as we have thousands of builds running at any one time so multiple project’s builds could all be making requests from the same IP address.


How can I delete my project?

You just need to unfollow the project in the project setting page. Once the last follower has stopped following the project, CircleCI will stop building. Please contact us us if you want to purge the project data from our database.
