Even with LLMs, I still like to review my code manually. However, I haven’t found a good visual diff viewer for this, so I wrote one myself in Rust.

Its sole purpose is to help you quickly skim through diffs. If you organize your code into folders named domain, use-case, application, and infra, the app will show the domain code at the top, allowing you to easily see the most important changes first.

Looks cool, seems this is a common problem, I built my own version too (pyor.review) but that started as a better PR reviewer compared to github, which quickly grew to a local PR reviewer too that let's me communicate with the AI session directly to review the files as I move before opening a PR.

mine is web based, not rust, and I built it with @pierre/diffs for rendering the diffs, which does provide a ton of the features I already needed.

I actually tried to build it as a native mac app first but that didn't go well as I couldn't find good libraries for what I was trying to build, so I scratched that and went to a full web app plus an electron unversal app.

Will definitely check it out
