Very fun to see my own PR on Hacker News!

This looks great. I'm probably gonna keep the threshold set to 0%, so a bit more gradient variety could be nice. Red-yellow-green maybe?

Also, can I use this on AI-generated code before creating a PR somehow? I find myself spending a lot of time reviewing Codex and Claude Code edits in my IDE.

Yeah we definitely want to make the gradient and colors configurable.

What form factor would make the most sense for you? Maybe a a cli command that renders the diff in cli or html?

colorbrewer has proven high contrast gradients and also color blind options.

a cli command with two options, console (color) and HTML opens all doors, right?

Either would work, I think. How I do it right now is that I let AI edit automatically, but then check the diff in Cursor before I stage my Git changes. May be different for others.

		Yeah, heatmapping the diff before creating a PR would need tighter IDE integration. We're working on cmux for this purpose. It's kinda an IDE, and it lives in the same repo: https://github.com/manaflow-ai/cmux. After we add the heatmap diff viewer into cmux, I expect that I'll be spending most of my time in between the heatmap diff and a browser preview: https://github.com/manaflow-ai/cmux/raw/main/docs/assets/cmu...

Perhaps more time that you would spend writing code yourself.
