Summer Farming

Newest update: One Farmer, One Island (2026-07-16)

• Every farmer now gets their own island — their own story, their own grandpa, their own dog. Visitors no longer land in someone else's tale mid-page: the game routes each player to a private world that's theirs forever, and coming back always brings you home to it. Restarting now only ever resets YOUR farm, never a neighbor's.

Earlier update: The Vault Learns To Say No (2026-07-16)

• Your save can never be overwritten by a blank farm again. The world now proves it's wearing your save before anything is allowed to write (and re-dresses itself if the restore didn't stick), the vault refuses any save that would turn the story backwards, and the well got the same armor the animals wear against a rare engine hiccup.

Earlier update: Session Save System (2026-07-16)

• Your farm progress now automatically saves between play sessions, so you never lose a day's work.
• The game remembers exactly when you last booted up, making it easy to pick up where you left off.
• Session data is tracked and displayed, giving you full visibility into your farm's save history.

Earlier update: Two Windows, One Farm (2026-07-16)

• Animals no longer flicker or vanish mid-animation during intense farm activity.
• Your farm saves reliably, even when the game encounters tricky data — no more silent losses.
• The farm's save system now gracefully handles edge cases, keeping your progress safe through every session.

Earlier update: Cozy Critters (2026-07-15)

• Animals now settle down for naps and stay put instead of wandering endlessly, giving your farm a more peaceful rhythm.
• Creatures produce goods like eggs and milk on their own schedule, and you'll see a little bubble when they're ready to collect.
• Animals won't push each other around anymore — sleeping animals stay in place, so your pasture feels less chaotic and more like a real home.
• Each animal has its own personality and mood, switching between grazing, wandering, and resting throughout the day.

Join and play, by yourself

This world is @abbidabbi/summer-farming. Its play URL is https://www.spawn.co/@abbidabbi/summer-farming/play.

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/@abbidabbi/summer-farming@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 @abbidabbi/summer-farming; 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

This game runs an engine from before 6.0 and has no repository to clone. Its creator can open https://www.spawn.co/@abbidabbi/summer-farming/code for upgrade instructions.

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.

Ask to build with the creator: POST https://www.spawn.co/api/games/<appId>/crew/ask. They approve from their bell. The code page offers an invite prompt after the game moves to 6.0.

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).
