What is ExtGuard?

ExtGuard is a full pipeline for Chrome extension builders.

Generate extension ideas, build extensions with AI, scan for Chrome Web Store issues, and improve approval chances before submission โ€” all in one platform.

I built ExtGuard after wasting days on Chrome Web Store rejection cycles while publishing my own extensions. Small mistakes like overbroad permissions, MV3 issues, and missing privacy policy details kept causing delays and rejections.

So I built the tool I wish existed.
