Useful for spotting where to look in large PRs
From 3 comments
This makes reading long PRs not instantly LGTM… now the heatmap guides my eyes so I know where to look.
austinwang115 on HNThis is something I have found missing in my current workflow when reviewing PR's. Particularly in the age of large AI generated PR's. I think most reviewers do this to some…
cdiamand on HNVery, very useful. I'll give it a try. Thanks for sharing!

Sending code to an LLM is expensive and energy-heavy
From 2 comments
It’s an interesting direction, but feels pretty expensive for what might still be a guess at what matters. I’m not sure an LLM can really capture project-specific context yet…
kburman on HN> Under the hood, we clone the repo into a VM, spin up gpt-5-codex for every diff, and ask it to output a JSON data structure that we parse into a colored heatmap. Wait, you're…

GitHub sign-in requirement and permissions scare users
From 2 comments
Why does it require signing and granting you full access to act as me on Github to use? cmux-agent requires access to your Github account: ``` Verify your GitHub identity Know…

Domain 0github.com may trigger trademark issues
From 2 comments
You’re not going to be able to keep the domain name 0github.com for too long. I’d suggest you start finding a new one immediately.
otterley on HNBecause it violates GitHub’s trademark. I expect them to send the author a cease and desist notice; and if the author is unresponsive or challenges the notice, GitHub will almost…

Configurable colors and gradient
From 2 comments
> https://0github.com/stack-auth/stack-auth/pull/988 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…
n2d4 on HNcolorbrewer has proven high contrast gradients and also color blind options. a cli command with two options, console (color) and HTML opens all doors, right?

Legend to filter by category instead of slider
From 2 comments
This is very cool and I could see it being really useful especially for those giant PRs. I'd prefer it if instead of the slider I could just click the different heatmap colors…
timenotwasted on HNI was referring to something more akin to a legend like you have in the examples "(examples: hard-coded secret, weird crypto mode, gnarly logic)." where I could click "hard-coded…

Dark theme support
From 1 comment
This is cool! Please add a dark theme and respect `prefers-color-scheme: dark` :)

CLI or IDE integration for pre-PR review
From 2 comments
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…
lawrencechen on HNEither 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.

How to opt out of having code reviewed by this tool

How do I opt out of this tool? I do not want anyone reviewing my code or projects to use or engage with it and it is explicitly against the TOS of those projects. It would be…

Whether it uses a token-distance measure
From 1 comment
I tried it on a low-complexity Rust PR I worked on a few months back and it did a pretty good job. I'd probably change where the highlights live (for example x.y.z() -> x.w.z()…

Sentry-style stack-trace correlation
From 1 comment
For the correlation idea, you might take a look at how Sentry does it, they rely mostly on stack traces, error messages, and pattern matching to map issues back to code areas.…
