Diffy: a cross-platform desktop code review app with a custom semantic diff engine
seatedro · x · 2026-10-22
Developer seatedro argues people stopped reviewing code because GitHub sucks — slow, ugly, and forcing you to manually parse cumbersome line diffs even on its good days.
His answer is diffy, a cross-platform desktop app that's fast and beautiful, built on a custom semantic diff algorithm (screenshot shows browsing 13,535 changed files in a Linux repo with function-level edits and rename detection). It aims to replace the GitHub web experience for PR review.
