Sapling SCM is a cross-platform, Git-compatible source control system from Meta, built in Rust, comprising the `sl` CLI, the Mononoke server, and the EdenFS virtual filesystem. It is designed for extreme scalability to monorepos with millions of files and commits while offering a user-friendly interface including an Interactive Smartlog web UI and VS Code integration.

Use cases

  • clone and work with existing Git repositories on GitHub
  • manage commits in a massive monorepo with millions of files
  • stack and iterate on commits without branch hassle
  • visualize and interact with repository history via a web UI
  • speed up checkouts in large repositories with a virtual filesystem

When to choose

  • you work in or with very large monorepos where Git performance degrades
  • you want a friendlier UX for stacked commits and history navigation
  • you want a Git-compatible client for GitHub workflows
  • you want an interactive smartlog UI or VS Code integration

When to avoid

  • you need the server-side (Mononoke) or EdenFS components in production - they are not yet supported publicly
  • your team is fully invested in standard Git tooling and ecosystem integrations
  • you need a GPL-2.0-licensed tool in a context where that license is a problem
