  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

    64.8

    score / 100

    Why switch from Fossil

    Another simple distributed system with a larger user base and an extension system.

    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. Jujutsu (jj) logo

    3. Jujutsu (jj)

    Best for: Developers who want a simpler, safer workflow while still pushing to Git hosts

    Open sourceWindows, macOS, Linux

    55.9

    score / 100

    Why switch from Fossil

    Modern distributed VCS with an operation log and undo for every command, storing history in plain Git repos.

    Pros

    • Works on existing Git repos, so teammates don't have to switch
    • Operation log makes any command undoable
    • Conflicts can be recorded and resolved later instead of blocking a rebase
    • Free and Apache 2.0 licensed

    Cons

    • Command-line only, with GUI support coming from third-party tools
    • No Git submodule or Git LFS support yet
    • New concepts take time to learn for long-time Git users
