FAQ

What languages are supported?

Currently, we support HTML, JavaScript, CSS, Python, and PHP. More languages may be added in the future.

Can I run any code?

For security reasons, some code execution is limited. HTML and JavaScript can be run directly in the browser, while Python and PHP code execution is simulated.

Is my code saved?

No, all code is processed locally in your browser. Your code is not uploaded to any server unless you explicitly save it using the download button.

Can I use external libraries?

For HTML/JavaScript, you can include external libraries via CDN links. For other languages, only standard libraries are available.
