CardCoder Studios is a collective of gaming websites and tools built by Alan O’Connor, who has been running trading card game websites since 2016. Its platforms serve communities around Pokémon, Digimon, One Piece, Sorcery: Contested Realm, Hearthstone, and other games, with additional sites marked as coming soon. The collective focuses on helping players do more than browse card lists.

Depending on the game and site, its services include searchable card databases, rules-aware deck builders, collection managers, pack-opening simulators, cube drafting, articles, and community forums. Advanced search tools let users filter cards by details such as name, effect, rarity, set, stats, color, and type. Deck tools support importing and exporting lists, sharing deck pages, and exploring opening hands.

Pokémon and Digimon players can also use Battle Table, a manual tabletop simulator offering solo and bot practice, online matches, chat, spectators, event logs, and replays. CardCoder Studios provides a Discord bot for card lookups across several games, with configurable server defaults, and game-focused guides and resources through its network
