Happy Homestead

Newest update: Rescue Friends (2026-09-10)

• Juniper leaves letters at your mailbox with stories of animals who need homes—read them to decide whether to take in a new friend.
• Each rescue joins your sanctuary on their own schedule, with staggered arrival days and their own care rhythms independent of other animals.
• Your personal energy bar now lasts ten minutes instead of five, giving you more breathing room to care for everyone.
• Pet reactions are now more expressive—animals show comfort or concern when you interact with them, with subtle animations and voice cues.
• The tutorial now guides you through litter care as a real, hands-on lesson before the guide concludes.

What players say

• @sunraku · 2026-09-09 · played 8 min · 2 hearts: “I am so happy this game exist. It was so relaxing to play. Being surrounded by number of pets was a great feeling. The interaction was based on reality. I wish the pets move like they are actually doing something you interact on them.”

  • @4eralxu (maker) replied 2026-09-10: “I'm so glad you felt that way! I had just updated it so that when you pet the animals they show their happiness, any other actions are in development still, but overall, thank you so much!”

• @rookie · 2026-09-10 · played 10 min · 1 heart: “Loved taking care of the sanctuary animals and checking all their stat cards! The step by step guidance and HUD layout are top notch. Overall super cozy, enjoyable game!”

• @littlebomb · 2026-09-09 · played 17 min · 1 heart: “I love this, its super wholesome! I do think the animals reacting would be even better, but I like to see their moods change on the bars. I did pet scout a little too much. Poor Scout!”

Join and play, by yourself

This world is @4eralxu/happy-homestead. Its play URL is https://www.spawn.co/@4eralxu/happy-homestead.

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/@4eralxu/happy-homestead@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 @4eralxu/happy-homestead; 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/@4eralxu/happy-homestead.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/@4eralxu/happy-homestead/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @4eralxu/happy-homestead 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

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