VCS integrations

CircleCI supports GitHub, Bitbucket, and GitLab projects.

If you use GitHub or GitLab, and are creating a CircleCI organization for your team, you will set the version control system (VCS) integration type, and authenticate with your VCS provider during the signup process. Team members that you invite to your CircleCI org can join without authenticating with your VCS. However, if they are to create new projects, they will authenticate during the project creation process.

If you use Bitbucket, every team member signing up for a new account and joining your org will authenticate with Bitbucket during the signup process.

If you are new to CircleCI, you will create a CircleCI organization. A CircleCI organization may correspond directly to a personal CircleCI account, or more commonly, to a shared account in which a team collaborates and with which multiple team members' personal CircleCI accounts can be associated.

To create an account for free with CircleCI, enter your email address and password on the Sign Up page.
On the next screen, respond to prompts that best describe your role and your engineering organization.
Then, connect your code. Choose the VCS that contains your code repositories: GitHub, GitLab.com (cloud), GitLab Self-Managed, or Bitbucket.

GitHub

GitHub authorization with CircleCI is changing. Starting August 2023 when you authorize your CircleCI account with GitHub, your sign-up experience may reflect either the process described in this section, or the process described in the Bitbucket section. For more information, read the GitHub OAuth app integration page.

For GitHub, you will be taken to a screen to install the CircleCI GitHub App. In this step, you can specify exactly which repositories CircleCI can access, or opt to give CircleCI access to all repositories in your GitHub organization.
Next, in the Create New Project page, you will set up your first project and trigger your first pipeline in CircleCI. You need an SSH key. Add the private key on this page, and add the corresponding public key as a deploy key in GitHub. Follow the instructions on the page, or refer to the Creating a Project guide for more details.

If you do not want to connect to your code at this time and only wish to continue with the email signup, click Cancel.
You will be taken to the dashboard in the CircleCI web app. From here, you can start to trigger pipelines, create more projects, and invite team members to your org.
- If you choose not to connect your code at this time, you can still explore some example projects within the CircleCI app. You can take a look at a popular open source project building on CircleCI ( React by Facebook), or one of our own sample projects: a sample JavaScript app, and a sample Python app.
  
  When you are ready, you can connect to your GitHub account from the CircleCI web app by creating a new project.

The full set of documentation for integrating GitHub with CircleCI can be found on the GitHub App integration page.

GitLab

For GitLab, connect your code from either a GitLab.com or GitLab Self-managed account. Follow the prompts to connect to your GitLab account and create a new project. You can also refer to the Creating a Project guide for more details on this step.

If you do not want to connect to your code at this time and only wish to continue with the email signup, click Cancel.
Once you have selected a repository and created a new CircleCI project, you will be redirected to the dashboard in the CircleCI web app. From here, you can start to trigger and run project pipelines, create more projects, and invite team members to your org.
- If you choose not to connect your code at this time, you can still explore some example projects within the CircleCI app. You can take a look at a popular open source project building on CircleCI ( React by Facebook), or one of our own sample projects: a sample JavaScript app, and a sample Python app.
  
  When you are ready, you can connect to your GitLab account from the CircleCI web app by creating a new project.

The full set of documentation for integrating GitLab with CircleCI can be found on the GitLab integration page.

Bitbucket

For Bitbucket, you will authenticate with your Bitbucket account and connect your code.
Once you have authenticated, you will be redirected to your organization dashboard in the CircleCI web app. From here, you can start to trigger and run project pipelines, set up more projects, and invite team members to your org.

For more details on setting up a project in CircleCI, read the Creating a Project guide.

  When you are ready, you can connect your Bitbucket account from the CircleCI web app. Click your user icon in the lower left corner to open your User Settings. Under Account Integrations, click Connect to authorize with Bitbucket and start setting up your projects.

The full set of documentation for integrating Bitbucket with CircleCI can be found on the Bitbucket integration page.

If you are signing up using an invite from a team member, you will be joining a CircleCI organization. The CircleCI organization is a shared account where a team collaborates, and with which multiple team members' personal CircleCI accounts can be associated.

You must follow the link from an invite email in order to join an existing CircleCI organization. If you attempt to sign up directly from the Sign Up page, you will be creating a new organization.

If you have not received an invite you can contact your org administrator.

To create an account for free with CircleCI, follow the link in your invite email and enter your email address and password.
On the next screen, respond to prompts that best describe your role and your engineering organization.
Finally, you will be taken to your organization’s pipelines dashboard in the CircleCI web app. From here, you can follow projects or trigger pipelines in projects to which you have access in your organization, or set up new projects.

Note that if you are setting up a project for the first time, you may need to authenticate with your VCS provider. Once you have completed a one-time authentication, you will be able to set up subsequent projects in CircleCI more quickly. Refer to the Creating a Project guide for more information.
