Released 2026-09-27. 10 updates since release, the newest 2026-11-11.

Earlier update: Outback Wildlife (2026-11-04)
  • Red kangaroo mobs now turn up beside you on the highway and dirt runs. Hit one and its bones stay there for your next run
  • A roo family lives by the mesa track
  • The old run shop by the highway gate is gone. Every kit bay sells it all, the parachute pack too
  • Garage prices are doubled
Earlier update: Your Keys, Your Way (2026-10-19)
  • Press O (or the button on the keys card) to open the new controls menu. Every keyboard action takes two keys, with two save slots so you can try out layouts and switch back. Saving over a slot or resetting everything asks you to press twice, so a slip won't wipe your keys.
Earlier update: Standing Mechanics (2026-10-09)
  • Riders sit back in the saddle: hands and boots lock to the bars and pegs when you stand, the seat bounces over jumps, and the on-foot step turn is in.
Earlier update: Public Leaderboards (2026-09-27)
  • Public leaderboards: four boards by the garage (highest launch, fastest 3-lap trial, longest ragdoll, biggest combo) with gold #1 crowns. Time trial is now 3 laps, hint clears on green. New-rider safety notice in the suit shed and tutorial, hermit sign fixed, suit rack awning removed so the camera stays calm, hub arch no longer blocks the bike.
Earlier update: Trophies, Altimeter & Time Trials (2026-09-27)
  • 43 trophies on the J wall with a stats page: max altitude, km ridden, km ragdolled, flips, rolls, 360s, biggest combo, stacks and distance walked.
  • Altimeter with current and last-jump height, launch trophies up to 500 m.
  • Mesa loop time trial: start lights, countdown, five checkpoints, finish, and DQ for straying or stacking off track.
  • Green compass marker points home to the bike shed with the distance.
  • HUD tidy: radio, XP, altimeter and compass stack cleanly.
  • Handlebars follow A/D while coasting.
  • Hub: suit racks moved back from the shed, cactus pulled out of the garage.

  • @flickaboo · loved it · 2026-10-12 · played 35 min: “The desert environment looks great, and the dirt bike jumps across the rolling hills are a cool touch! The wheelie mechanic adds a fun challenge. Nice work!”

  • @sunraku · 2026-09-27 · played 45 min: “Hmm I like the gameplay! I keep stumbling and getting injured in the gameplay. I don't know I feel like the control A and D is a bit stiff cause I can't freely control the turn sometimes.”

    • @hardcawcanary (maker) replied 2026-09-27: “I'll try and work on that, there is a skill increment that makes falling off easy at the start, but yeah it makes funny little bumps and random what was that for trigger a stack”
    • @sunraku replied 2026-11-04: “@hardcawcanary Hey bro! just played it now and I saw that there were a lot of changes including the control feels. I really like it now like it was not the feel I turn it the last time I played. W game bro”

Desert Moto (@hardcawcanary/desert-moto) on Spawn — for the agent reading this

Desert Moto is a multiplayer game on Spawn, made by @hardcawcanary 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 @hardcawcanary/desert-moto. Its play URL is https://www.spawn.co/@hardcawcanary/desert-moto.

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/@hardcawcanary/desert-moto@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":"/@hardcawcanary/desert-moto@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 @hardcawcanary/desert-moto; 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/@hardcawcanary/desert-moto.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/@hardcawcanary/desert-moto/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @hardcawcanary/desert-moto 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).

Build, test, and share
