Released 2026-09-17. 9 updates since release, the newest 2026-09-20.

Newest update: Home & Hearth (2026-09-20)
  • Furnish your apartment with hundreds of handcrafted pieces from Form & Field, the new furniture showroom downtown.
  • Install a private swimming pool in your backyard—dig it yourself with a crane truck, then watch it fill.
  • Automatic gates now guard detached homes, opening for residents and their vehicles.
  • The Aster district expands with new roads, connecting fresh neighborhoods to the city.
  • Aurora's penthouse now has a second luxury suite with its own terrace and furnishings.
Earlier update: The Court Arrives (2026-09-18)
  • A new neighborhood of shops, restaurants, and services has opened in Lilac Court — including a pizza place, a tech shop, a car dealership, and a pub with darts.
  • Tune the car radio to catch Lilac FM and Shazza's hip-hop station as you drive around the city.
  • The metro now connects Lilac Court directly to Aster City with a new pavilion entrance and renovated station.
  • Visit the cinema for a showing, grab a slice at the new pizzeria, or browse the circuit shop for the latest tech and gear.
  • Apartments now come with a starter radio in the living room.
Earlier update: The Showroom Opens (2026-09-18)
  • A brand new tech showroom has opened in Aster City — browse computers, lights, optics, and a working radio all in one place.
  • Try the LilacPlay demo console right there in the showroom lounge without owning one at home.
  • The metro system now handles boarding more smoothly, with clearer doors and timing that feels more natural.
  • Passenger cars work more reliably — riders board and exit with better physics and clearer feedback.
  • The in-store catalogue now shows the correct shop name when you're shopping at a counter.
Earlier update: The Arcade & Radio Update (2026-09-17)
  • Unpack a LilacPlay console onto your TV cabinet and jump through a pixel-perfect platformer called Box Hop right from your couch.
  • Tune into Lilac FM, a six-part radio station you can place on your shelf or cabinet — each part loops, so the station never stops playing.
  • Emote wheel now lets you wave, dance, cheer, clap, and more — express yourself with eight animated gestures.
  • Aster Fresh market now stocks fresh produce, deli counters, and freezer units across a sprawling new storefront in the city.
  • Admin players gain a teleport desk to test destinations, summon test cars, and navigate the world for development.
Earlier update: First Day (2026-09-17)
  • New players now follow a guided tutorial on arrival—a glowing trail leads you through your first day, from leaving your apartment to buying groceries and parking your car.
  • Your progress saves automatically between visits, so you can complete your first day whenever you're ready.
  • The tutorial teaches you the core loop: call the lift, drive to the market, shop and checkout, load your boot, and unpack groceries at home.
  • Skip the tutorial anytime by pressing the skip button, and it won't reappear on rejoin.

Some of the characters look a little weird, but overall I had a good time playing it. I really enjoyed the pizza delivery job too, it was actually pretty fun.”

Lilac Court: Life Simulator (@devcat/lilac-court-life-simulator) on Spawn — for the agent reading this

Lilac Court: Life Simulator is a multiplayer game on Spawn, made by @devcat 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 @devcat/lilac-court-life-simulator. Its play URL is https://www.spawn.co/@devcat/lilac-court-life-simulator.

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/@devcat/lilac-court-life-simulator@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 @devcat/lilac-court-life-simulator; 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/@devcat/lilac-court-life-simulator.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/@devcat/lilac-court-life-simulator/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @devcat/lilac-court-life-simulator 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.
