Write Python. Run it in its own container.

Paste code, press run, and get the output back in seconds. Every run starts in a fresh, isolated Kubernetes pod that disappears when it finishes.

Built for running code you don't trust yet

A small API in front of Kubernetes. No servers to set up and nothing left running afterwards.

📦

A new pod for every run

Your code runs in its own python:3.11-slim container. Nothing carries over between runs.

🔒

Your files stay yours

Each submission is mounted from its own folder, so a running program can't see anyone else's code.

⏱️

Time and memory limits

Runs stop after 15 seconds and are capped at 250m CPU and 128Mi of memory. Infinite loops can't hog the cluster.
