    Open sourceSelf-hostableWindows, macOS, Linux, Self-hosted

    79.8

    score / 100

    Why switch from Jujutsu (jj)

    Single-binary DVCS that bundles a wiki, tickets and web UI, if you don't need Git compatibility.

    Pros

    • Bug tracker, wiki, forum and web UI built into the repository
    • Single executable and SQLite storage make install and backup easy
    • Light enough to self-host on a cheap VPS or Raspberry Pi
    • Permissive 2-clause BSD licence

    Cons

    • Small community and few third-party tools or integrations
    • Mainstream code hosts only support it through a Git mirror
    • Deliberately limits history rewriting, which Git users may miss

  2. Mercurial logo

    2. Mercurial

    Best for: Teams that want distributed version control with a simpler, safer command line than Git

    Open sourceWindows, macOS, Linux

    68.8

    score / 100

    Why switch from Jujutsu (jj)

    Mature distributed VCS with a similarly friendly command set and extensions like changeset evolution.

    Pros

    • Consistent, smaller command set that is easier to learn
    • Powerful features stay opt-in through extensions
    • Full local history makes most operations fast and offline
    • Free software under the GPLv2 or later

    Cons

    • GitHub and GitLab.com don't host Mercurial repositories
    • Far smaller ecosystem of GUIs, integrations and tutorials than Git
    • Fewer developers already know it, so onboarding takes more effort

  3. Pi

    3. Pijul

    Best for: Developers curious about patch-based version control with cleaner merges than three-way merge

    Open sourceLinux, macOS, Windows

    42.3

    score / 100

    Why switch from Jujutsu (jj)

    Patch-based model where conflicts are first-class and resolutions never need redoing.

    Pros

    • Changes commute, so cherry-picks and merges stay consistent
    • Resolved conflicts stay resolved across branches
    • Partial clones of large repositories
    • Free software under GPL 2.0 or later

    Cons

    • Still a 1.0 beta release
    • Small ecosystem: few GUIs, hosts or CI integrations compared with Git
    • No official Windows binaries; installation is mainly through Cargo
