The conversions
The monster mechanics in the current release are a GURPS fan conversion by Enraged Eggplant, from their collection Monsters (11 May 2024), used with their unrestricted permission. The permission statement is published below.
Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
Dungeons on Automatic added the review pass, the encounter maths, the art, and the GCS export. Every record carries its own credit line and conversion notes inside the data — open any monster on the bestiary page and expand Where this one came from to read them.
Licensing
Fan-authored GURPS monster statistics adapted and republished with unrestricted author permission; attribution retained.
The published library is released under CC BY 4.0. You may use these monsters at your table, in your own tools, and in things you publish, as long as you keep the attribution. The credit line above is the attribution; copy it as-is.

The art
Every portrait, token, and hex token in the bestiary is original art generated for this project with OpenAI image generation, in a single house style so the library looks like one book rather than a scrapbook. Hex tokens are derived from the top-down tokens and cut to each creature's stated footprint.
No publisher art, logo, or trade dress is hosted here or generated to imitate one. The images are yours to download and use with the monsters they belong to.
What is deliberately not here
Dungeons on Automatic is an unofficial game aid. Steve Jackson Games book text, published monster stat blocks, art, logos, and trade dress stay with their publisher and are never republished through this site.
Published monster packages must name their source basis at the record level, and each source family keeps its own provenance category rather than being merged into a vague bucket. Nothing reaches the public library without passing that review.
You should still own and use the books on your shelf. The source-book filtering in the desktop app exists so the generator stays inside the library you actually have.
The data itself
The whole library is one JSON file: monsters, stats, provenance, and asset URLs. If you want to build something on top of it, start here rather than scraping the page.
