Diffs

View code changes from any public GitHub diff—PRs, comparisons, commits, diffs, and patches—with a super-freaking-fast, beautiful, and virtualized interface by putting revision.city/diffs/ in front of any github.com path.

- github.com/org/repo/pull/number+ revision.city/diffs/org/repo/pull/number

Private GitHub accessOptional

Sign in with GitHub to view private diffs, expand collapsed context, and raise rate limits. Access stays in a secure cookie in this browser.

Enter a URL above, or use one of these:

https://github.com/oven-sh/bun/pull/30412
https://github.com/nodejs/node/pull/59805
https://github.com/ghostty-org/ghostty/pull/12291

You can also compare millions of lines with ease, like v6...v7 of Linux. This sometimes crashes mobile browsers, and GitHub unreliably serves diffs over 100k lines with a delayed first byte.
