Chrome Goldmine

Chrome Goldmine is a curated database of 9,656 expired Chrome extensions with revenue projections, rebuild difficulty scores, and competitor analysis, designed for indie hackers and solo developers seeking micro-SaaS opportunities.

What is Chrome Goldmine?

Chrome Goldmine provides an interactive Notion workspace and a full CSV export of 9,656 expired Chrome extensions. Each entry includes revenue estimates (based on user count and category benchmarks), a rebuild difficulty rating (Low / Medium / High), competitor analysis highlighting active alternatives and their gaps, and key selling points extracted from original descriptions and user reviews. The product is created by Raf Vantongerloo and is updated quarterly with new expired extensions.
