How do I run code in the browser?

Select your language, write or paste your code, and click Run. For HTML/CSS/JavaScript projects, a live preview panel updates in real time as you type. Python, TypeScript, SQL, and Lua code can be executed directly in the browser without any server.

Is the code editor free to use?

Yes, the code editor is completely free with no signup, no ads, and no usage limits. All code runs locally in your browser, so your source code is never uploaded to any server.

What editor features are available?

Features include 10 themes (light and dark), Vim keybindings mode, 45 keyboard shortcuts, auto-completion and IntelliSense, code formatting on save, multi-file tab editing, search and replace with regex support, and the ability to share code via URL.

Can I share my code with others?

Yes, you can share your code by generating a shareable URL. The URL encodes your code, language selection, and editor settings so anyone with the link sees exactly what you see — no account required.

Does the code editor work on mobile?

Yes, the editor is fully responsive and works on smartphones, tablets, and desktops. Touch-friendly controls and a mobile-optimized layout ensure a smooth coding experience on any device with a modern browser.
