GitFlow

GitFlow is an online tool for learning Git through hands-on lessons and scenarios. It is built for engineers who ship code, and it focuses on practicing Git in a simulated terminal without affecting a real repository.

The service presents 116 lessons across 11 tracks and 62 scenarios, with more than 35 Git commands. Its curriculum includes foundations, branching and merging, inspection and debugging, undo and recovery, remote use with GitHub, release and operations workflows, advanced techniques, daily workflows, Git internals, teamwork and code review, and forensics and investigation. The site highlights practical situations such as merge conflicts, rebase recovery, and force-push recovery. In the sandbox, users can stage, commit, branch, merge, rebase, revert, inspect reflog, stash, and cherry-pick, while real Git semantics run against an in-browser repository. The commit graph also updates in real time.

GitFlow is delivered in the browser and described as a real terminal with no real damage. It offers a lesson flow, a scenarios browser, a leaderboard, and sign-in / account features. The site states that it is free.
