Self-Hosting with Private Archidekt Decks

Archidekt does not support OAuth, so private deck access requires your credentials. Create a .env file:

cp .env.example .env
# Edit .env with your Archidekt username and password

Important: Never deploy credentials on a shared/public server. Private deck access is for self-hosted instances only.

Data Sources

• Scryfall — Card data and prices (updated daily from TCGPlayer, Cardmarket, Cardhoarder)
• EDHRec — Commander metagame data and recommendations
• Archidekt — Deck building and storage
