Gitpod is an open-source developer platform automating the provisioning of ready-to-code developer environments..

With Gitpod your team can instantly start coding with fresh, ephemeral and fully-compiled dev environments for each new task - no matter if you are building a new feature, want to fix a bug or do a code review.
