Tabletop RPG systems and books, catalogued by the people who play them.

GrimoireCodexDB is a free, community-maintained database of tabletop roleplaying games: their systems, books, series, publishers and creators. It supplies book and system details to Grimoire, the self-hosted TTRPG library manager.

Anyone can browse the Codex or use its API without an account. Contributors sign in with Discord, GitHub or Google; we use their name, email address and profile picture only to set up their account and credit their edits. Every change is reviewed and kept in history.
