What is RandomSimulation?

RandomSimulation generates fully self-contained, runnable web simulations on demand. Simulate anything from simple particle systems to games and websites. It returns a complete HTML/CSS/JS page that renders in real time.

The web version uses an API AI LLM; the offline app uses Ollama locally for private, no-internet inference. You will need to download Ollama and pull a model to use it.

How it works

• Type a prompt describing the simulation you want. Press enter. Be detailed for better results.
• The simulation is automatically rendered in real time.
• Code is streamed, highlighted, and can be copied.
• The Random button will generate a Random Simulation.
• Each simulation costs money. If you enjoy RandomSimulation please consider donating to support it.

FAQs

• What can I simulate? Anything. Examples: Conway's Game of Life Simulator, Neon Particle simulation,
• Can I save simulations? — Yes, click the copy button and paste it into an editor or notepad. Run the file in a browser by opening it or dragging and dropping.
• Why didn't my simulation work?? It fails a lot, LLMs make mistakes. They are getting better all the time.
• What do you do with my simulations and data? I don't collect anything. I don't see any code or simulations you generate. The code is generated by a LLM provider on their servers and they send it to your browser to render on your computer.

Download Offline App

COMING SOON... Windows installer (~75 MB). Runs fully offline only dependeny is Ollama. Best for privacy.
