Deadliest Catch

Newest update: The Bycatch Update (2026-07-16)

• Unwanted species now tangle in your nets alongside your target catch, forcing you to sort and manage a messier haul.
• New marine creatures bring unpredictable challenges — some valuable, some worthless, all competing for space in your hold.
• Your catch composition now shifts with the season and location, making every run feel different.
• Discarding bycatch costs time and money, adding weight to every decision about what stays and what goes overboard.

Earlier update: Something Blinks Below (2026-07-16)

• Linger too deep and IT no longer watches from afar — an enormous eye manifests beside you, blinking, while the countdown runs. More fish in the water (the column restocks itself when it thins). Lantern upgrades actually brighten from the first rank. The fishing line now hangs true from the rod tip. Glows mean something: if it shines, you can take it. Sharper sky and moon on every machine, readable help scroll, and a proper tagline on the title screen.

Earlier update: The Sky Comes Back (2026-07-16)

• The night sky now paints on every deck — some crews were sailing under a blank void while the stars refused to bake. The fishing line hangs true from boat to hook again, and the whole voyage runs lighter on old rigs and phones.

Join and play, by yourself

This world is @beach/deadliest-catch. Its play URL is https://www.spawn.co/@beach/deadliest-catch/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/@beach/deadliest-catch@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 @beach/deadliest-catch; 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/@beach/deadliest-catch/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).
