A tiny WXT + React browser extension that shows the very first commit of the current GitHub repository in a git-log styled popup. Built for fun and curiosity—like git blame, but even less useful. Hence: git blade.
Compatible with: All Chromium-based browsers (Chrome, Brave, Edge, etc.) and Firefox-based browsers (Firefox, Zen, etc.)
When learning from a project, I often read the official README and docs. Sometimes I also want to know who made the first commit and what that initial commit looked like. This extension answers that in one click.
- Detects if the active tab is a GitHub repository
- Finds the repo's default branch and fetches the very first commit
- Displays commit in terminal-like git log style (hash, author, date, message)
Requirements: Node 18+.
Install dependencies and start in Chrome dev mode:
npm i
npm run devFirefox dev mode:
npm run dev:firefoxProduction builds:
npm run build # Chrome (mv3)
npm run build:firefox # FirefoxFollowing WXT publishing guidance:
npm run zip # Chrome/Edge ZIP
npm run zip:firefox # Firefox ZIP + sources ZIPWXT will generate files in .output/. For Firefox, a sources ZIP is also created which reviewers use to rebuild our extension. Ensure the sources ZIP can be built on its own:
npm i
npm run zip:firefoxactiveTab– to read the current tab URL and detect GitHub.
No background networking beyond GitHub’s public API.
- Private repos are not handled (requires auth; out of scope for first release)
- Extremely large repos may take a moment to resolve the first commit
- GitHub API rate limiting can temporarily block requests
- WXT (MV3 build, zips, and submit tooling)
- React 18, TypeScript 5
