Describe a game.
Kurambit builds it, plays it, and keeps only what gets better.

An open-source game studio run by the coding agent you already use. It works in Godot and Blender, play-tests every build with a separate tester, and judges each change blind.

One email when your invite is ready. Never shared. Privacy

01 The loop

Not a prompt box. A studio with a process.

Anyone can ask a model for a game. Kurambit wraps it in the habits of a real team and runs them every round, so a worse build never lands.

  1. 01

    Brief

    A sentence or two about the game you want. Genre, mood, art direction.

  2. 02

    Build

    Your agent writes the engine project and models assets in Blender, keeping every source editable.

  3. 03

    Play

    A separate tester session plays the build and reports what it actually saw.

  4. 04

    Judge

    Two builds, compared blind. Ties and worse builds are reverted, never merged.

  5. 05

    Keep going

    Rounds continue until the budget ends, leaving a demo-shaped game for you to polish.

Verdict
KEEP

worse builds are reverted

Every round leaves a record of what was played and why it was kept.
02 Inside the studio

Your game on a stage. The agent at your side.

Watch the game come together, play the real build in the app, and ask for changes in plain words. Every session stays on your machine.

A game open in Kurambit: the stage with the game's poster and a Build and play button, the agent's work on the right
Kurambit's home: a brief box asking what we are making today, with game covers below
03 Real tools, real files

Everything it makes, you can open.

No black boxes. Each game is its own git repository with editable sources, so you can keep working with or without Kurambit.

04 Questions

Good to know.

When can I use Kurambit?

We are letting people in small batches so every new studio gets a good first game. Join the waitlist and we will email you when your invite is ready.

What do I need?

A Linux x86_64 machine today and one signed-in coding agent: Codex, Claude Code, Cursor, Grok Build, OpenCode or Antigravity. Kurambit installs Godot and Blender for you.

What does it cost?

Kurambit is open source under the MIT license. It runs on the agent subscription you already have; one model is enough for the whole loop.

Can it make any kind of game?

Any genre. One brief aims for a game shaped like a Steam demo: something you can play, judge and keep improving with the studio.

What happens to my email?

It is stored privately and used only to contact you about Kurambit. It is never sold or shared, and you can ask to be removed at any time. Read the privacy note.

Is the code open?

Yes. Every line is on GitHub.
