Pkmn Master Set tracks your Pokémon card collection set by set and printing by printing — holo, reverse, 1st Edition — synced everywhere, organised into binders that match the ones on your shelf.
A tracker for collectors, and the card-data API it runs on — also yours to build with.
Per-printing collection tracking, digital binders with sharing, want-lists, multi-language data, and it installs on your phone. Free to use; Master Set Premium unlocks the power tools.
Every set, card and printing as clean JSON — or the whole catalog as one SQLite file. Self-documenting, AI-readable, tokens minted the moment you subscribe. For developers →
Everything you actually do with a collection, and nothing you don't.
A holo and its 1st Edition are different pieces of cardboard — each gets its own tick and count.
Pocket sizes, covers, page-by-page layout — then add the whole binder to your collection in one press.
Unguessable links anyone can open — trade lists, brag pages, want-lists. Free for everyone.
Browsing is free for everyone. Tracking is free with an account. Power tools are $2.99 — Master Set Premium.
