A Workspace is an environment that allows you to manage your Bitrise apps and the team members working on the apps. You can create multiple Workspaces, and you can be invited to Workspaces by other Bitrise users.
To be able to add apps and run builds, you either need a Workspace or you need to get added as an outside contributor to an app’s team.
Workspace membership is based on groups: Workspace owners can create groups and decide which members belong to which groups. A given group can be assigned to work on an app: all members of the same group will have the same level of access to the app.
Workspaces can take advantage of SAML Single Sign-On: we have guides for setting it up with several major identity providers.
