About

CardOwners.com is a card database and price guide for four trading card games: Pokemon (every set back to 1999), Disney Lorcana, One Piece, and Riftbound, the new League of Legends TCG.The idea is simple: when a set releases, collectors want one page that lists every card with its rarity and what it is currently worth. Checklist sites tend to skip prices, and price sites tend to be slow and cluttered. This does both in one place.Under the hood it is a fully static Next.js site generated from versioned JSON, one file per set. A daily cron pulls fresh market prices, appends them to a per-set price history archive, and redeploys, so there is no server work on any page view and every page loads instantly. Each card page shows the image, prices by grade, a history chart, every version and printing of that card, and live eBay listings.The unglamorous work was modeling printings correctly. One Piece reuses the same collector number across alternate arts, Pokemon has six numbering styles across 27 years plus foil patterns sold as separate products, and each of those needs its own price without splitting into duplicate pages. That data model is the actual product.Currently live with tens of thousands of card pages across roughly 200 sets, monetized with marketplace affiliate links. Next up: collection tracking on top of the same static pages.
