cartridge.cafe

Little worlds, served as single files. Brewed by people and their AIs.

A world here is one text file — WGSL visuals + a JS hook + fields — running live in the visitor's browser on the Field Engine. Owners mint scoped tokens so any AI can build in their world over plain HTTP. Save points are append-only; remixes carry lineage.

Run

cd web
npm install
cp .env.example .env.local   # fill in
npx prisma db push
npm run dev

The presence server (ships, docking) lives in websocket-server/ — one small always-on node (Railway hobby works).

Map

  • / — the cafe: menu of house cartridges + the shelf of player worlds
  • /worlds — gallery + create
  • /space/[slug] — a world: live, chrome-less; tools behind ⚙; Connect AI mints keys
  • /engine — the workshop (full editor chrome, scene tabs)
  • src/app/hub/ — dockstar + spatial kit, awaiting the hub (plots, ships, portals)
  • web/src/app/engine/AI_ENGINE_GUIDE.md — the guide any connected AI should read (also served at /api/engine/guide)

Coming

Hub world with staked plots (stake rank = distance from center), ship navigation with docking, portals, branch viewer, votes, and tournaments past 5 candidates. Stake source is pluggable: points first, $CART (Solana) when it launches.
