DCSS is a venerable open source roguelike. Seeded games are an opt-in variant and there's a small community around sharing "interesting" seeds or ones particularly suited to certain builds or playstyles.

This runs dcss's dungeon gen and dumps seed data via a patched lua script. It's not meant to be a full enumeration of seeds, nor a complete dump of any particular seed. Just a way to find some interesting ones. I have about 1.3m for the most recent major version and you can add any valid seed to the corpus.

And seeds are strictly PER VERSION so if you want to play one on webtiles make sure's it's serving one of the versions I have seeds for and not trunk.

It grew out of a tool I'd been dragging around for years and finally decided to put a web interface over.

OCaml, sqlite, htmx alright alright.
