Sprint.ly is agnostic as to which source control management (SCM) software you are using. We prefer the potent combination of Git and GitHub ourselves, but we understand that's not for everyone. You can get all of the benefits of SCM integration by creating a post-commit hook on your local repository that sends an HTTP POST that looks like a GitHub post-receive hook to your product's post-receive URL.
Additionally, we support both Beanstalk and bitbucket out of the box.
