Released 2026-10-27. 4 updates since release, the newest 2026-10-27.
Newest update: Crew View (2026-10-27)
- Your crew now sees you sitting in the pilot seat while you fly, and the cabin camera screens show the live outside view to everyone aboard. Returning to Earth lights up your own launch pad with a ring, a beam and a YOUR PAD marker so you land in your own spot.
Earlier update: Cargo Hold (2026-10-27)
- Every ship's hold now has a cargo cabinet: store rocks, artifacts, fuel cans, patch kits and medkits, and take them back anytime. Sparrow holds 30, Kestrel 60, Albatross 120, and it moves with you when you upgrade. New Medkit (+40 health) in the shop's gear tab.
Earlier update: Two Aboard (2026-10-27)
- The Sparrow now carries two: a top bunk for a friend riding as crew, only the owner flies. New admin panel for the creator, labelled needs bars, real banking in flight, wings built into the hull, and tidal-wave work on Thalassa.
Earlier update: Tutorials and a putt-putt buggy (2026-10-27)
- New players get a skippable 6-step guide on arrival, and first-time pilots get skippable pilot training at the helm. Pad buggies now sound like petrol golf carts and show their own speedo and driving controls instead of the ship's flight panel.

Starfarer 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/starfarer. Its play URL is https://www.spawn.co/@devcat/starfarer.
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/starfarer@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/starfarer; 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/starfarer.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.
