Diffinity 作者: Resonance Research

Diffinity highlights exactly-copied code blocks in GitHub pull requests, so you can identify refactored or moved code from genuinely new code at a glance.

When you view a PR, Diffinity scans the diff and highlights added lines that match code removed elsewhere in the same PR, so as a reviewer you can focus on what's actually new.

Features
- Two-pass matching: exact, and re-indented
- Theme-aware purple highlighting for GitHub light and dark modes
- Runs entirely in your browser, your code never leaves your device
- Fast: a typical PR is analyzed in well under a tenth of a second

Free & paid
Diffinity is free for your first 20 pull-request analyses. After that, a one-time license key unlocks unlimited use. The license key is the only data ever sent off your device, and only when you choose to activate it.
