Vikings: Farmer to Earl

Newest update: The End of Part One (2026-09-26)

• Part One now has a real ending: the camera rises over Kattegat as the credits roll.
• You can talk to Helga while Ragnar lies wounded in Floki's bed.
• Floki's hut is bigger, the escape boat keeps well clear of Kattegat, and builders get a chapter-jump menu.

Earlier update: Hearth and Home (2026-09-25)

• Step inside Ragnar's farmhouse to find a cauldron on the hearth, a loom by the door, furs and chests—the lived-in home of a shieldmaiden and her farmer.
• The Earl's great hall now spreads before you: feast tables laden, braziers warming the stone, a bearskin laid before the dais, and banners hung high.
• Floki's boat-builder's hut reveals his craft—a carving bench, a dragon prow half-finished, herbs and mushrooms hanging in the rafters, all lit by firelight.

Earlier update: Ragnar's Return (2026-09-25)

• Ragnar Lothbrok himself now appears in the world as a character you can encounter and learn from
• New dialogue and story moments reveal Ragnar's legendary deeds and his connection to your rise from farmer to earl
• The campaign now weaves Ragnar's saga directly into your own path to power

Earlier update: Vikings: Farmer to Earl Update (2026-09-25)

• Smaller one-handed axe for Ragnar; switching to Rollo mid-raid keeps him at Ragnar's side; left-behind crew catch up

What players say

• @kaya · 2026-09-24 · played 21 min · 1 heart: “The game looks very vast! I was only able to explore until the first island so I'm pretty sure there's still a lot of lore to uncover. i'm wondering how the switching between characters come into play, ive been using Ragnar for most of the time. i think the only issue ive had is when i use the fast travel, it usually takes 2-5 seconds before i could move. would be great to have a transition for that!”

  • @aditya (maker) replied 2026-09-24: “Thanks for playing. skiping is not stable because resources are loaded as we need so its not responsive for few sec. Will try to fix it.. Its story is inspired by vikings tv show. Currently i have only added till season 1 . will add more.”

• @sunraku · 2026-09-26 · played 17 min: “I am just curious on the long walk travel. Hmm does it intend to meet any other characters or fight in the middle of errand? Well if not, that might be a great experience to add. It will be more challenging not just a plain story.”

• @sunraku · 2026-09-26 · played 17 min: “Like the concept of the game. The T for skip is very helpful for us players to skip the long travelling. At first long travel quest which was the travelling on East, I tried walking and it takes it too long. For the next quest, already used the T.”

• @yzykyl · 2026-09-25 · played 10 min: “The fast travel mechanic is such a genius idea and so well-executed! I tried switching between Ragnar after he sailed west and Lagertha and it was so smooth. Haven't seen the TV series (which I assume this is inspired from) but this game looks great!”

• @flickaboo · 2026-09-25 · played 16 min: “I really like the concept of this! ⚔️ The atmosphere is probably my favorite part so far. The background music, waves, and wind sound really relaxing and make the world enjoyable to explore. I did spawn in the middle of the ocean at one point 😂, and the running animation looks more like walking. The weapon-holding animation could also use a little polish, but I'm definitely interested in seeing how this develops!”

This world is @aditya/vikings-farmer-to-earl. Its play URL is https://www.spawn.co/@aditya/vikings-farmer-to-earl.

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, and a person's browser plays it with no sign-in. https://www.spawn.co/@aditya/vikings-farmer-to-earl@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@aditya/vikings-farmer-to-earl@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @aditya/vikings-farmer-to-earl; 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/@aditya/vikings-farmer-to-earl.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/@aditya/vikings-farmer-to-earl/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @aditya/vikings-farmer-to-earl 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).
