Core Features

FEATURES

Everything you need for a complete development environment, running entirely on your machine.

Multi-Language

Python, JavaScript, TypeScript, C/C++, and SQL — all running client-side via WebAssembly runtimes.

Offline First

After the first load, works entirely offline. Electron build needs no internet ever.

Privacy by Design

Your code never leaves your browser. Zero server, zero data leakage — privacy by architecture.

Zero Cost

No servers means no per-user cost. Every user's device IS the compute. Host on a static CDN.

Desktop App

Electron build for Windows, macOS, and Linux. Air-gapped deployable via USB — no cloud required.

Instant Start

No cold starts, no container provisioning. Open tab, start coding in under 2 seconds.
