Drift City

Earlier update: RYU DYNO & My Cars (2026-10-17)

• New RYU DYNO tuning garage across from Minato Oil: buy engine, turbo and tyre stages for your car. New MY CARS button: see every car you own and press DRIVE to switch. Only a car's owner can drive it, friends ride passenger. Fewer cops, more traffic, and traffic now gives way when you have right of way.

Earlier update: Drift City FM (2026-10-17)

• Car radio is in: press Q in any car to flip through EUROBEAT, CITY POP, PHONK, NEON synthwave and LOFI. Your passenger hears it too.

Earlier update: Hayate Motors (2026-10-17)

• HAYATE MOTORS is open east of KAZE: buy the AE86, Golf, 240 or Mustang with drift yen
• Every car you own waits in your garage (G)
• Respawn car button brings your car right beside you
• Chat shows in the car now: a feed bottom-left, and passengers see the banner

Earlier update: Shout It Out (2026-10-17)

• Chat now flashes as a big banner top center for everyone. Cops are easier to shake: slower chase cars, shorter sight, quicker escapes. Mirrors fixed so you can see who's behind you. The new game restart is gone.

Join and play, by yourself

This world is @devcat/drift-city. Its play URL is https://www.spawn.co/@devcat/drift-city.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@devcat/drift-city@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @devcat/drift-city; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@devcat/drift-city.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@devcat/drift-city/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @devcat/drift-city in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share
