FREQUENTLY ASKED
QUESTIONS

Is this just a CSV list?+

No, it's a complete research system. The CSV is included for quick reference, but the real power is in the interactive Notion workspace. It includes MV3 impact scores, rebuild difficulty estimates, revenue projections, case studies, action plans, and filtered views. Think of it as a "rebuild playbook" for 9,656 extensions, not just a list.

What does "Competitor Analysis & Key Selling Points" include?+

For each extension, we identify existing alternatives still active in the Chrome Web Store and highlight their strengths and weaknesses. We also extract the original extension's key selling points from its description and user reviews, giving you a clear picture of where you can differentiate.

How accurate are the revenue figures?+

They are conservative monthly ranges from category benchmarks (typical conversion and pricing for that niche), not the original extension's earnings and not a promise. We show historical users as the hard number. If a listing cannot support a sober range, we say so. 30-day refund if the data isn't useful.

Can I see the data before I pay?+

Yes. The table above is a live 20-row sample with the same filters you'll use in Notion, and one full 12-point report is openable for free. The remaining 9,636 listings unlock after checkout.

Do I need to know how to code?+

No. The database includes rebuild difficulty scores (Low / Medium / High) to help you find extensions that match your skill level. Many "Low" difficulty extensions can be built with no-code tools or AI coding assistants. The Quick Start Guide covers both technical and no-code paths.

How often is the database updated?+

The database is updated quarterly. New expired extensions are added, and existing entries are refreshed with updated competitor data. All updates are delivered automatically — you pay once and receive every future update at no extra cost.

What is your refund policy?+

We offer a 30-day, no-questions-asked refund policy. If you're not satisfied with the database for any reason, simply email us within 30 days of purchase and we'll process a full refund immediately.
