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

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Theme 1 – Documentation & visibility matter

"Please put up this or another screenshot as the first thing you see in the README - please!" – yboris

Theme 2 – Real‑world reasons to rewrite commit metadata

"Yes, for instance it could be useful if someone’s been accidentally committing with a bogus email address." – xp84
(also cited by simonw: “Sometimes I split a Git repo into two, and I want to preserve the commit history (authors and dates) on the files ….”)

Theme 3 – Tool usefulness vs. LLM‑driven expectations

"A tool like this never sees the light of day without an LLM. Git is complicated and use case for this is rather niche." – MattGaiser

These three themes capture the most‑frequent topics in the discussion: the need for clear visual documentation, concrete use‑cases for editing author/date metadata, and the broader conversation about when such tools are worthwhile and how they relate to LLM‑assisted development.

🚀 Project Ideas

CommitCraft: Interactive Git Metadata Table Editor

Summary

  • A cross‑platform Tauri desktop app that visualizes a repository’s commits in an editable table, lets users edit author, date, and message with regex find‑replace, and creates a backup branch before rewriting.
  • Provides a safe, UI‑driven bulk commit‑metadata editing experience that lowers the barrier for developers needing to fix authorship or dates.

Details

Key Value
Target Audience Developers who need to clean up commit authorship, dates, or messages across many commits (e.g., fixing bogus emails, reconstructing history)
Core Feature Interactive table view with inline editing, regex‑based bulk replacement, automatic backup branch, safe rewrite via git commit-tree
Tech Stack Tauri + Rust + React UI + git2-rs library
Difficulty Medium
Monetization Revenue-ready: Freemium with optional paid backup‑retention add‑on

Notes

  • Directly answers the HN demand for a screenshot‑first, user‑friendly interface; the table UI mirrors the original project’s appeal.
  • Addresses concerns about “cutting with a knife” by offering precise, reversible edits and clear backup steps.

GitFlowStudio: VS Code Extension for Bulk Commit Edits

Summary

  • A VS Code extension that adds a dedicated view pane to edit commit author, date, and message fields directly within the editor, supporting bulk regex replacements and preview diffs.
  • Delivers seamless IDE integration for developers who prefer to stay inside VS Code while performing bulk commit metadata fixes.

Details

Key Value
Target Audience Developers who work primarily in VS Code and need occasional bulk commit metadata adjustments
Core Feature In‑editor table editor with undo/redo, backup branch creation, regex replace, real‑time git preview
Tech Stack TypeScript + VS Code Extension API
Difficulty Low
Monetization Hobby

Notes

  • Eliminates the “unreadable on iPad Safari” friction by staying fully desktop‑centric and offering immediate visual feedback.
  • Leverages VS Code’s popularity to make the tool instantly discoverable for the target audience.

WebGitEdit: Browser‑Based Safe Commit Metadata Rewriter

Summary

  • A lightweight web app (hosted on GitHub Pages) that connects to a user’s repository via the GitHub API, displays commits in an editable grid, enables bulk author/date/message edits with regex, and pushes changes safely after creating a backup branch.
  • Offers a no‑install, cross‑device UI that satisfies the HN request for mobile‑friendly and screenshot‑ready tools.

Details

Key Value
Target Audience Casual contributors, open‑source maintainers, and teams needing quick, cross‑device commit clean‑up without local installation
Core Feature Responsive grid UI with inline editing, regex bulk replace, automatic backup branch, serverless commit rewrite using git-filter-repo
Tech Stack React + Vite + GitHub REST API + Node.js serverless function
Difficulty Medium
Monetization Revenue-ready: Subscription per private repository (e.g., $5/mo)

Notes

  • Provides the screenshots and mobile responsiveness that HN commenters asked for, making the tool instantly trustworthy.
  • Enables discussion around safe, web‑based Git manipulation and could inspire further UI‑driven Git utilities.
