TCGer is a trading card game discovery and shopping platform that helps collectors find specific cards and the shops selling them. Its service brings together listings from independent stores, letting users browse cards by title, game, and shop, and compare available market listings. The site features recent and upcoming set information, including release dates and card counts, alongside indicators of stock availability.

Shoppers can explore a broad range of games, such as Pokémon, Magic: The Gathering, One Piece, Yu-Gi-Oh!, Disney Lorcana, Digimon, Flesh and Blood, and Weiss Schwarz. Individual card pages show details such as the associated set, price, and number of shops with listings; for example, the homepage highlights Crobat V from Shining Fates. TCGer also helps users locate participating shops, with store details such as location and listing count, and notes when pickup is available.

Account features include signing in, maintaining a collection, and creating a want list, supporting collectors as they track cards and work toward completing their collections
