What is Chrome Goldmine?
Discontinued browser add-ons with existing historical user counts populate the Chrome Goldmine database, giving software builders ready-made concepts to code and monetize. Each row in the Notion workspace maps out a specific tool that previously gathered an audience before shutting down due to Manifest V3 migrations, developer abandonment, or policy shifts. Instead of guessing market demand, solo founders can inspect real performance numbers collected across numerous software categories.
9,656 entries with revenue estimates and user figures
Every project listing documents concrete performance metrics rather than vague concepts. Records display historical user counts ranging from thousands to over 90,000 installs, alongside estimated monthly and annual revenue figures starting under ten thousand dollars and scaling past one hundred thousand. Rebuild difficulty ratings categorize each idea by technical complexity, helping solo developers match projects to their coding skills and available development hours.
12-point reports, competitor analysis, and CSV downloads
Beyond basic user metrics, entries feature 12-point reports detailing why each tool died, current market competitors, key selling points, and step-by-step rebuild plans. Power users can export the raw data as a full CSV file for custom filtering and sorting. Quarterly updates add new discontinued extensions to the workspace, and purchases include lifetime access to future database additions without recurring monthly fees or subscriptions.
