Released 2026-09-29. 5 updates since release, the newest 2026-09-29.

Newest update: Back to HQ (2026-09-29)
  • You can now abandon a job mid-grind from the menu and return to the shop — the yard heals back up and you lose the pay, but you're free to pick another job.
  • If you get stuck on a swing, chair, or other prop, you can stand back up with E, jump, or a walk key.
Earlier update: Mobile Makeover (2026-09-29)
  • Hold your phone upright and the camera pulls back to fit the whole yard on screen—no more cramped corners.
  • Any tool you put down won't stick to you anymore; dropped tools clear out within a second so they won't ghost around.
  • The HUD scales down and stays neat whether you're holding your phone tall or wide.
Earlier update: Fresh Start (2026-09-29)
  • Your first piece of gear is free at the shop, so you can suit up right away without grinding first.
  • When you accept a job from the shop, the van drives straight there—no more awkward positioning.
  • The grinder automatically rolls back off the stump after grinding it out, no matter who's driving.
  • Abandoned jobs now heal themselves: the yard grows back and the grinder frees up for the next pro.
  • Old tools and hoses left stuck on you from past visits are cleared when you arrive at a new job.
Earlier update: Fresh Start (2026-09-29)
  • Reloading into a fresh room no longer leaves you stuck holding the hose or unable to hop back on the grinder.
  • Stepping into a new area now properly dismounts you from any leftover ride, so the camera resets right.
Earlier update: malformed arms and blood defect (2026-09-29)
  • fixed arms positioning when holding tools. removed accidental bloom as well

Stump Pro (@25th/stump-pro) on Spawn — for the agent reading this

Stump Pro is a multiplayer game on Spawn, made by @25th 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 @25th/stump-pro. Its play URL is https://www.spawn.co/@25th/stump-pro.

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/@25th/stump-pro@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 @25th/stump-pro; 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/@25th/stump-pro.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/@25th/stump-pro/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @25th/stump-pro 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

Publish when the game is ready for players. Share its play link so friends can join.
