Released 2026-11-07. 8 updates since release, the newest 2026-11-09.

Newest update: Garage Upgrades (2026-11-09)

The garage frees your mouse between rounds, so you can click to buy upgrades. Parts now belong to the ride you bought them for, and they come back when you drive that ride again.

Earlier update: Big Air on County Road (2026-11-09)

County Road's jumps are way bigger: the Hollis Hump is almost twice as tall, the launch kicker is taller, and the whoops throw you higher. The new name is on the logo and the trackside banners. On a sideways phone, the HUD no longer covers the stick and buttons.

Earlier update: County Road gets wild (2026-11-09)

County Road now has three whoops on the north straight, a smashable hay-bale chicane on the east straight, and the Hollis Hump jump between tire stacks. New ground also loads much faster.

Earlier update: Poseidon Falls (2026-11-08)

A new gorge runs past Poseidon on Hogback Eight, with a waterfall pouring from under the statue. Hogback's crossing now sits on a hill crest. The Poseidon Motors sign faces the track.

Earlier update: Hollis County Tune-Up (2026-11-07)

Reset cars come back a bit behind on the track, away from oncoming traffic
No more cloud shadows on the green hills
A Strange Orange Tongue concert billboard by County Road
A simpler opening: the title over golden sky, then the cars roll in

@kaya · loved it · 2026-11-08 · played 11 min · 1 heart: “realized that in this game, slow and steady wins the race, and a lil bit of dirty tactics too. pushing enemies off was probably the best strategy just so i could keep the lead lmao. steering was quite hard in this game though, and it gets out of--”
- @kaya replied 2026-11-08: “control real fast, especially when youre trying to make a turn. slowing down does the trick though!”
@makeriffic · loved it · 2026-11-07 · played 10 min · 1 heart: “Only managed to get to third place lol. This was fun and chaotic at the same time. I think the announcer/host just makes the game much more fun to play. I get there are many modes, right? on my second run the pit stop is not repairing damage anymore.”
@flickaboo · loved it · 2026-11-07 · played 9 min · 1 heart: “Really enjoyed this one! The controls and objective are easy to figure out, and the figure-8 track makes the races even more chaotic and fun. Crashing into other cars never gets old hahaha. Definitely would play again!”

Crunch-em-up Derby Racing is a multiplayer game on Spawn, made by @nickyp in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.

Join and play, by yourself

This world is @nickyp/crunch-em-up-derby-racing. Its play URL is https://www.spawn.co/@nickyp/crunch-em-up-derby-racing.

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, and a person's browser plays it with no sign-in. https://www.spawn.co/@nickyp/crunch-em-up-derby-racing@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@nickyp/crunch-em-up-derby-racing@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @nickyp/crunch-em-up-derby-racing; 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/@nickyp/crunch-em-up-derby-racing.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/@nickyp/crunch-em-up-derby-racing/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @nickyp/crunch-em-up-derby-racing 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, a video (.mp4) — 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).
