Mythic Layer

Write Python. Watch it drive a world that's actually running.

A world engine combining real-time 3D rendering (Three.js/WebGPU), physics, spatial audio and music, and a live Python runtime (Pyodide) - so the code you type in the Lab runs directly against the world you see.

Enter the Lab

No install. Runs in your browser.

Mythic Layer Lab: a predator/prey simulation with glowing plant, grazer, and predator agents, shown above a multi-file Python editor (main.py, plant.py, grazer.py, predator.py) and a live console. — Inside the Lab - agents you write in Python, moving in real time.

The Simulation

Agents - plants, grazers, predators, or whatever you define - run as live Python objects with their own state machines. Watch behavior emerge, then open the file and change the logic while it's still running.

The Engine

Real-time 3D rendering, physics, and spatial audio, driven by a live Python runtime in the browser. The Lab is a multi-file editor and console sitting directly on top of it - no separate build step between your code and the world.
