Jj guide

Version control, stacked changes, and git-compatible history from the terminal. Built by Jujutsu.

Open CLI packages the install path, verify step, and safe-start workflow so this tool can move from “interesting CLI” to something you can actually use. It also integrates with skills.sh so each CLI comes with the right companion skills, not just a binary and a docs link.

When to apply

  • version control, stacked changes, and git-compatible history from the terminal.
  • You need git workflows in both local dev and CI.
  • You need version control.
  • You need stacked changes.
  • You need git-compatible history.
