Show HN: Git-knife – edit commit messages, authors, and dates like a spreadsheet

Git-knife is a new GUI tool that enables IT organizations to safely edit git commit metadata (messages, authors, dates, and committer information) in bulk across repositories, filling a critical gap where existing tools either lack GUI interfaces or treat commit metadata as immutable. This addresses compliance, audit trail correction, and developer onboarding scenarios while maintaining data integrity through automatic backups and safety warnings before rewriting pushed history. For organizations managing large codebases or those requiring strict commit hygiene standards, this tool could significantly reduce the manual burden of history corrections and bulk author identity fixes.
