0github.com is a diff viewer that adds heat maps for GitHub code reviews.
When programming, diff tools that display differences in source code are indispensable. In particular, linking them with version control tools to check the differences between versions not only helps you understand the changes between versions, but is also often useful for discovering bugs, making them a standard usage. ' 0github.com ' can extract and compare code differences from
Heatmap diff viewer for code reviews
https://0github.com/
0github.com is unique in that it features a 'heat map' that displays code differences by color according to the level of attention required. While a typical PR review bot focuses on whether a code fragment is a bug, 0github.com also checks whether the fragment is OK, even if it seems problematic:
- Is confidential information such as private keys
-Any deprecated encryption methods being used?
・Is the logic strange?
Regarding internal operation, the target repository is cloned into a VM and processed with GPT-5-Codex for each difference. Therefore, the target repository must be public. To use it, simply replace the domain name 'github.com' in the GitHub pull request URL with '0github.com' to access it. A sample link is available on the site, so let's start by accessing GitHub.
fp8 amd cstyle by b1tg · Pull Request #12999 · tinygrad/tinygrad · GitHub
https://github.com/tinygrad/tinygrad/pull/12999
Now that we have confirmed that the pull request actually exists, let’s replace the URL and access “0github.com.”

https://0github.com/tinygrad/tinygrad/pull/12999
When you access the page, 'Loading' will be displayed for a few seconds.
The screen displayed as '0github.com'.
On the left side of the screen there is a slider called 'Should review threshold.' If you move it to the left, areas with low scores will also be displayed in the heat map, and if you move it to the right, only areas with high scores will be displayed.
If you hover your mouse cursor over an area displayed in the heat map, a hint will appear showing you the specific problem. For example, the following suggestion seems to be asking, 'A variable has been renamed, but is this a problem?'
The corresponding section is shown below. The issue states that 'the renamed variable is being used.' Combined with the previous issue, it seems like there's no problem, but you should be careful to make sure the variable before the rename isn't being used elsewhere.
The following issue seems to have a fairly high score based on the color of the heatmap. The issue states that 'hard-coded slices are at risk of vulnerability.' Indeed, you should be careful to ensure that input is processed correctly and that attempts to process unexpected input do not cause vulnerabilities.
The following also received a high score. The error stated, 'The property being accessed has changed from src[0].dtype to srg[2].' I wonder if this was the change the developer intended.
The following also has a high score. The issue is that 'a tuple is accessed using the hard-coded
The following comment states, 'It's strange that private functions are at the module level.' It's difficult to determine if the comment is correct just by looking at the part that's pointed out, but since it seems that the comment was made after examining the entire module, it seems that code reviews should also be done at the module level.
As we've seen briefly, we can confirm that areas with high scores on GitHub's heatmap are areas that require careful code review. Because the heatmap reflects even small differences that a human would miss, it helps reduce the risk of inadvertently introducing defects that slipped through code review into the production environment.
