About
Chrome Goldmine is a research database for indie makers and solo builders looking to rebuild profitable Chrome extensions. It contains 9,656 expired extensions, each with historical user counts, rebuild difficulty ratings, revenue estimates (ranging from under $10K to over $100K annually), competitor analysis, and step-by-step implementation guides. The data updates quarterly.
Each extension listing shows why it stopped working (Manifest V3 incompatibility or abandonment), estimated monthly revenue potential, and the category it served. You can filter by difficulty, category, and revenue range. The database comes as a Notion workspace and CSV file for one-time access.
The site also publishes guides on finding, validating, building and monetizing rebuilt extensions, with deep dives into specific niches like Pomodoro timers, dark mode tools, and Gmail integrations.
Chrome Goldmine stands apart by focusing exclusively on expired Chrome extensions with proven demand. Rather than speculating on new ideas, each of the 9,656 listings represents an extension that people already installed, then abandoned. You get historical user counts, rebuild difficulty ratings, revenue estimates, competitor analysis, and a step-by-step rebuild plan for each one. The database updates quarterly and comes as a one-time purchase with a Notion workspace and CSV export, no subscription required.
- Problem
- Finding a profitable Chrome extension idea means guessing which gaps exist or building something nobody wants.
- Solution
- Chrome Goldmine shows 9,656 extensions people already installed and used, then stopped working. You rebuild with an existing audience and revenue potential.
