I’ve always been a believer that the best business ideas aren’t found in a “eureka” moment – they are hidden in plain sight within the data.
While researching the Chrome extension market, I decided to stop guessing and start analyzing. I took a deep dive into over 246,000 extensions to see what’s actually happening in the ecosystem. What I found was a massive, looming shift that most people are overlooking: the Manifest V2 (MV2) deprecation.
The Opportunity
Right now, Google is phasing out MV2. My analysis showed that over 34,000 extensions – which collectively account for more than 400 million installs are at risk of breaking because they haven’t migrated to Manifest V3.
This isn’t just a technical update; it’s a massive market gap. Thousands of proven ideas with built-in audiences are about to become “abandoned.”
Key Findings from the Data:
- The “Stale” Goldmine: A huge percentage of extensions with 100k+ users haven’t been updated in over two years. They are proven concepts waiting for a modern competitor.
- Permission Bloat: Many successful extensions are using high-risk permissions that users are increasingly wary of. There is a “privacy-first” niche waiting to be filled in almost every category.
- Underserved Categories: While productivity is crowded, niches like “Developer Tools” and “Privacy” have high user demand but lower competition for MV3-compliant tools.
I built ExtensionDB to turn this massive spreadsheet into a searchable tool for other indie hackers. Instead of spending weeks on research, you can filter by manifest version, user count, and last-updated date to find your next project in seconds.
The data is clear: the best time to build a Chrome extension isn’t “someday” – it’s right now, before these 400 million users lose the tools they rely on.
