• (2025-06-18) Георгий Александрович Куклин: lifesaver
• (2024-10-02) Mikhail Miatselski: The only way to debug webgl. Can't imagine learning without it. Also helpful while debugging opengl code compiled to wasm. Can't believe google is going to delete it from store
• (2024-09-09) Joseph Merdrignac: I learned a lot thanks this extension. Sadly it is no longer supported because of new Chrome policies. Can we do something to help?
• (2024-03-03) Sebastian Oscar Lopez: I'm in love with this debugger
• (2024-02-23) nerdError: Man this thing is SO GOOD. It literally saved performance of my games, because i was able to actually debug it and test things, instead of random guesses. DEVS, I LOVE YOU!
• (2024-01-22) Stephen: Doesn't work in any browser. Cant select a canvas. "Please, select a canvas in the list above" but doesn't ever populate that list, so its not usable as of Jan 2024.
• (2024-01-19) Roman Bodnarchuk: Broken layout, "Please, select a canvas in the list above." while there is no list. It is broken and not working.
• (2024-01-05) Ken Russell: Spector.js is the best-of-breed tool for understanding and debugging arbitrary WebGL applications. It's even useful when debugging issues in the browser itself - it helps narrow down the sequence of WebGL calls that lead to incorrect rendering. Thank you for creating this extension and maintaining it over so many years!
• (2024-01-02) John Wick: Hello, Can you add support for depth viewing?

• (2022-11-20) Jason Borejszo: Please update the extension to use the latest optimized API of the new chrome. The older deprecated calls in the latest chrome make the extension inoperable. Thank you for you work and this extension, it is one of my favorites. "A page or script is accessing at least one of navigator.userAgent, navigator.appVersion, and navigator.platform. Starting in Chrome 101, the amount of information available in the User Agent string will be reduced. To fix this issue, replace the usage of navigator.userAgent, navigator.appVersion, and navigator.platform with feature detection, progressive enhancement, or migrate to navigator.userAgentData." Because of this it no longer opens the new tab with model info... and thus the extension no longer works correctly.
