SellProof is product research software for e-commerce sellers and dropshippers who sell in the EU and UK. It answers one question before you spend money on stock or ads: is anyone really making money selling this product?
SellProof searches Meta's official Ad Library API across 28 EU and UK markets in one run. It keeps only the shops selling your exact product, filtering out unrelated ads and big retailers, and returns a clear verdict: PASS, UNSURE or FAIL, with the reasons, competitors' shop prices and their longest-running ads. The verdict rules are transparent and fully adjustable.
Key features:
- Product validation with a PASS / UNSURE / FAIL verdict and reasons
- Winning ads finder: long-running ads per country, in your niche or any niche
- Competitor tracking: ads each brand launched, scaled and stopped since your last check
- Competitor price collection from their shops
- Seasonal product support (one-year look-back)
- AI-assisted search words for every language
- Reports in HTML, CSV and Markdown, with a searchable report library and swipe file
- Guided mode for beginners and a compact Pro mode
- English and German interface, light and dark mode
SellProof runs as a desktop app on Windows, macOS (Apple Silicon) and Linux. It connects through the user's own free Meta developer app, uses only the official API (no scraping), and keeps all products, results and reports on the user's computer.
Pricing: one-time payment, license for up to 3 computers, no subscription. A free browser demo with sample data is available.
Note: Meta's API only returns product ads delivered in the EU and UK, so US ads are not covered.
