As answered by people managing Layercode UseCSV and TCG-Completist.
TCG-Completist's answer:
It covers 11 trading card games in one account, runs entirely in the browser (no app to install) and is free without ads. The focus is completing sets: you see the missing cards with Cardmarket prices, what finishing a set costs, and you can scan cards with a phone or webcam. Cards are counted per language and finish (normal, foil, reverse).
TCG-Completist's answer:
Python (FastAPI), SQLite, vanilla JavaScript, hosted on a Hetzner Cloud server in Germany behind Caddy. Card data comes from public sources such as Scryfall and TCGdex; prices from the daily Cardmarket price list.
TCG-Completist's answer:
If you collect more than one game, you do not need a separate tool for each. You get set-by-set tracking, a camera scanner, deck building with format checks, a trading hub between members and price alerts in one place, in 8 languages. It is free, has no ads and needs no installation.
TCG-Completist's answer:
Collectors who want to complete sets, from casual players with a binder to people who collect several games. Many of them buy on Cardmarket and want to see at a glance what is missing and what it costs.
TCG-Completist's answer:
TCG-Completist is a one-person project started in August 2026 by a collector who wanted a simple way to see exactly which cards are missing from a set and what completing it costs. It grew from Magic to 11 games and is developed in the open with feedback from its members.
