A reference library built for the table
TheCrazyGM is an open gaming knowledge base for Pathfinder 1e and D&D 5e — a searchable reference library, a Forge for building your own content, and shared worlds to keep a campaign's homebrew in one place. The library is free on every plan, and every record shows where its rules came from.
The Library
Spells, feats, items, races, classes, archetypes, and monsters — full-text searchable, cross-linked, and readable on a phone during a session.
Browse the libraryRules Compendium
The rules themselves, organised into chapters — character creation, combat, magic, skills, and a GM reference section.
Read the rulesThe Forge
Build characters, NPCs, encounters, and your own rules content. The build engine does the bookkeeping; publishing generates the license notice for you.
How publishing worksWorlds
A namespace for a campaign's homebrew — share it with your group as a viewer or editor, or publish it for everyone.
Browse worldsThe reference content on this site is Open Game Content, reproduced under the Open Game License v1.0a (Pathfinder 1e) and CC‑BY‑4.0 (D&D 5e SRD). Every record carries a provenance footer that walks its licensing chain back to the source book, and anything published through the Forge gets the same treatment — a Product Identity check and a generated Section 15 notice.
If you want to understand the licensing side properly, the OGL 1.0a Guide is a plain-language learning path, and the Publisher Directory lists the imprints whose content is attested here.
TheCrazyGM is a small, independent project — not a storefront and not an ad network. It's operated by Sustainable Resource and Business Development Enterprise, and it's in early access: things are still being built, and the D&D 5e side is deliberately narrower than the Pathfinder 1e side rather than claiming parity it doesn't have.
Paid plans (Hearth, Table, Publisher, Studio) fund the hosting and the build work; the library and its provenance tooling stay free on all of them. You can also support the project directly through the Founder Pack or sponsorship.
