As answered by people managing Nullstack and CardHunt.
CardHunt's answer:
CardHunt scans eBay for Pokémon cards with PSA 10 upside, checks that each listing is still for sale, and estimates the centering from the listing photos before you click. Every find shows the chance of a PSA 10 (from the PSA population report) and the expected profit after grading, shipping and selling fees, and it flags the traps: cards that look like a big win on paper but lose money on average.
CardHunt's answer:
Most tools show either a price or a PSA population count. CardHunt combines both with live eBay listings: the chance of a PSA 10, the expected profit after grading, shipping and selling fees, a centering estimate from the photos, and the total cost including shipping and import to your country, so you can decide before you buy. These are estimates, not guarantees: the PSA population report only counts cards people chose to submit, and centering is an estimate from photos, not a grade.
CardHunt's answer:
Pokémon card collectors and flippers who buy raw cards on eBay to send to PSA, and want to know which listings are actually worth grading before they spend money on the card and the grading fee.
CardHunt's answer:
CardHunt is built solo by Stefan in the Netherlands. Judging a raw Pokémon card for grading is hard because you need the price, the PSA population data and the card's condition at the same time, and the good listings sell fast. CardHunt does that math for every eBay listing, checks that it is still for sale and estimates the centering from the photos, so you only spend your time on cards that can actually pay off.
CardHunt's answer:
Next.js and React with TypeScript on the frontend (hosted on Vercel), a Python FastAPI backend (hosted on Railway), PostgreSQL on Supabase, Clerk for sign-in, the eBay APIs for live listings, and computer vision to estimate centering from listing photos. Prices and PSA population data come from third-party data providers.
