DiffScope

Browse a GitHub release diff one file at a time.

Paste any GitHub compare URL and DiffScope fetches the diff, lists every changed file in a sidebar, and only shows the ones you select. Useful when a release spans dozens of files and you only care about a few.

Usage

Paste a GitHub compare URL:

https://github.com/owner/repo/compare/v1.0...v2.0.diff

Then check or uncheck files in the sidebar. Use the pattern box to select files by glob (src/**/*.cpp) or regex (/\.h$/).

Deploy

Single static HTML file — no build step.

1. Put index.html in a repo
2. Enable GitHub Pages (Settings → Pages → Deploy from branch)
3. Done

Notes

• GitHub doesn't allow browser fetches of .diff URLs directly, so requests are proxied through corsproxy.io. Only the raw diff text passes through — no credentials.
• For private repos, download the diff locally (curl ... > patch.diff) and paste the contents — or self-host a CORS proxy.
