Fullset is a fan-made online platform for organizing and tracking trading card collections. Designed for collectors, it currently supports Yu-Gi-Oh!, Pokémon, Magic: The Gathering, and Riftbound, with additional trading card games planned. The service presents collections in a binder-style layout, helping users monitor completed sets, identify missing cards, and follow their progress through dynamic completion indicators.

Fullset also offers a price calculator that estimates a collection’s value and provides detailed summaries, including its most valuable cards and values by set. Collectors can add graded cards and sealed products to their profiles, keeping a broader record of their items and making selected highlights easy to share with the community. Other available tools include a deck builder, CSV import and export, and premium features; some options, such as additional item categories, are marked as forthcoming.

Accessible on computers, phones, and tablets, Fullset is built to let users manage their collections across screen sizes. It provides account registration and community access through Discord.
