GitUI vs Mercurial

GitUI provides a Git GUI-style workflow inside a terminal, controlled with the keyboard and supported by context-based help. Users can inspect changes and commit, amend, stage, unstage, revert, or reset at file, hunk, or line level. It also supports saving, applying, popping, dropping, and inspecting stashes. Branch tools cover creation, renaming, deletion, checkout, and remote branches, alongside pushing and fetching. Users can browse or search the commit log, inspect committed diffs, and work with submodules. Commit workflows support several Git hooks; GPG commit signing is listed with shortcomings. GitUI is free under the MIT License, which includes an as-is warranty disclaimer. Listed platforms are Android, Linux, macOS, and Windows, with desktop platform support listed for Linux, macOS, and Windows. The project README describes GitUI as beta and notes that bugs or missing features may occur, while also describing it as reasonably stable for personal use. It does not fully replace the Git shell, lacks sparse repository support, and requires explicit configuration of an HTTPS credential helper.

Mercurial is a free, distributed source control system for managing development history. Each developer keeps a full local copy of that history, so work can continue without a network connection or central server. It is designed for projects of any size and supports diffs, commits, branching, and merging. The software runs on Windows, macOS, and Linux; binary releases are also listed for Solaris 11 Express and other platforms. Installation options include system packages, Windows winget, Homebrew, PyPI tools, and source builds. Python extensions can add or change commands and access core functionality. Official extensions cover tasks such as Git command mapping, email notifications, and external diff tools. Mercurial supports sparse checkout and nested repositories; large-file handling is available through an extension. It is licensed under the GNU GPL version 2 or later. One security caveat: carefully constructed Git subrepositories can pose a clone-time code-execution risk, so they are disabled by default.
