The product
What git-knife is building
git-knife is an open-source desktop application for changing Git commit metadata in a table-like interface. It can edit commit messages, author and committer identity, and dates; it also offers bulk replacement across selected metadata fields. The project uses the system Git command-line tool rather than implementing Git itself, and its README describes previewing changes, creating a backup ref before a rewrite, warning about pushed history, and handling signed commits. Source and release materials are public, and the project provides native release assets for early users.
From the maker
A small desktop tool for the awkward parts of Git history repair
The v0.2.0 release was published August 12, 2026 and added branch selection without checkout plus signed-commit awareness. git-knife is still an early open-source project, but its explicit backup and preview mechanics make it more relevant than a generic Git GUI for founders and developers who need to correct local commit metadata without touching file content.
