Decklists, built for players.
DeckDen is a home for your trading card game decks — build them, keep track of them, and show them off, all in one clean, fast place.
Why I built this
I'm a multi-game TCG player myself, and the thing I kept running into was that every game has its own separate deck tracker — one app for Yu-Gi-Oh!, another for Pokémon, another for whatever else you're into. None of them talk to each other, and none of them are built around the actual player. That never made much sense to me, because most TCG players I know don't just play one game — you've got a Pokémon deck for league, a Yu-Gi-Oh! deck for locals, and something else you're playing on the side.
So I wanted one place where the player comes first: a single profile that shows everything you play, across every game, tied to one username.
"Yo, check my UA deck on DeckDen" — that's the whole idea. One link, one username, your whole collection of decks across every game you play.
What DeckDen does
DeckDen lets you build and save decklists across multiple trading card games, search a live card database while you build, and publish decks publicly so other players can browse and get ideas from your builds. Every account gets a public profile page that collects the decks you've chosen to share — across every game you play, not just one.
How it works
- Create an account. Sign up with a username, email, and password — it takes seconds and it's free.
- Start a deck. Pick a game, name your deck, and choose a format and description if you'd like.
- Search and add cards. Look up cards by name and add them straight into your Main or Extra deck with live artwork.
- Share it, or keep it private. Make a deck public to show it off on your profile and in Browse Decks, or keep it just for you.
Supported games
DeckDen currently supports three games, each with its own card search hooked up to a real card database:
- Yu-Gi-Oh! — search backed by the YGOPRODeck database, with separate Main and Extra deck sections.
- Pokemon — search backed by the Pokémon TCG API.
- Union Arena — search backed by DeckDen's own growing card database.
Open source
DeckDen is an independent, ongoing project — built with Next.js and Tailwind CSS on the frontend, and FastAPI with PostgreSQL on the backend. The code is public on GitHub.
