Overdraw visualizer recommended in docs is no longer available

However, the repo hasn’t been updated in 3+ years, and when you click the link to their Chrome extension page, it’s broken.

  3. Are the docs in an open source repo I can open an issue on, or submit a pull request to?

The docs are open sourced. The repo is here:

You can see if Pixel Overdraw still works
