We have open source self-hosted (Community Edition), open core self-hosted (Enterprise Edition), or hosted (GitLab.com). It's more like GitHub + Chat + CI + CD + Heroku + New Relic (early stages). Where Heroku forces you to use their platform, GitLab allows you to use any platform that runs Kubernetes.
