# The TCG OS > One platform for every trading card game. Collectors track, value and complete > their collections for free; vendors run a single inventory spine across physical > shop, online store, our marketplace, eBay and card shows. Four games are live > today — Pokémon, Magic: The Gathering, Yu-Gi-Oh! and One Piece (160,000+ cards > across 1,800+ sets) — with more on the way. The full set library and card pricing > are open to everyone with no login. ## What it is The TCG OS (https://www.thetcgos.com) serves two audiences: - **Collectors** — catalogue what you own, dive into per-game lore (Pokédex entries, oracle text, rulings), track set completion, watch live portfolio value, cost basis and top movers, and buy cards directly from the live inventory of vetted, approved vendors in our marketplace (every seller reviewed before they can list, so you always know who you are buying from). Free. Card prices display in GBP today; US card-level pricing is rolling out. - **Vendors** — the differentiator is omnichannel inventory: one stock spine that feeds five sales channels (physical shop, the vendor's own online store, our marketplace, eBay and card shows). A sale on any channel instantly decrements every other, so there is no overselling and no double-listing. ## Pricing - Collectors: free. - Vendors: a single base tier — £25/month (UK) or $29/month (US). These are deliberate, natively-set prices, not FX conversions. - Every new vendor gets **3 months free with no credit card required**; payment details are only requested if they continue after the trial. ## Feature status (honest) Live today: a four-game catalogue (Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece) with set library + pricing, collection tracking, valuation, vendor inventory spine, omni-channel management (one stock spine across physical shop, online store, our marketplace, eBay and in-person shows — sell on any channel and every other updates in real time), a managed marketplace storefront that puts vendor inventory in front of collectors, eBay listing sync, show selling, and deals & trade-ins. On the roadmap: more games (Disney Lorcana, Star Wars Unlimited, Digimon). US card-level pricing is pending currency-provenance confirmation. ## Key pages - Marketing home: https://www.thetcgos.com/ - Set library by game (free, no login): - Pokémon: https://www.thetcgos.com/g/pokemon/sets - Magic: The Gathering: https://www.thetcgos.com/g/mtg/sets - Yu-Gi-Oh!: https://www.thetcgos.com/g/yugioh/sets - One Piece: https://www.thetcgos.com/g/onepiece/sets - Sitemap: https://www.thetcgos.com/sitemap.xml ## Notes Not affiliated with Nintendo, Creatures, GAME FREAK or any trading-card publisher.
