Our Verdict

Best for

Engineering teams working in large repositories who want a stack-based alternative to Git's branching model.

Skip if

Your team is small and already comfortable with standard Git branch workflows.

What is Sapling?

Sapling is Meta's open-source source control system, designed to make version control simpler and more scalable than traditional Git workflows, especially at the size of Meta's own monorepo. It is compatible with existing Git repositories, so teams can clone and work with GitHub-hosted projects while using Sapling's own command set. A core difference from Git is its stack-based workflow: Sapling automatically tracks commit heads without requiring explicit branch creation, eliminating detached HEAD states, and lets developers navigate stacked commits with commands like sl next and sl prev. It also includes custom GitHub pull request integration, letting sl pr submit create a pull request for every commit in a local stack, plus a browser-based GUI (sl web) and a VS Code extension.
