Frequently Asked Questions

Find Quick Answers

What programming languages are supported?

The editor supports over 50 languages including JavaScript, Python, HTML, CSS, PHP, Java, C++, Ruby, Go, TypeScript, SQL, and many more. The language list is automatically updated based on the CodeMirror library.

Do I need a GitHub account to use this tool?

Basic editing and code execution work without a GitHub account. To save code as gists or fetch private repositories, you need to provide a GitHub personal access token. You can generate one in your GitHub account settings.

Is my code saved or stored anywhere?

Code is processed in your browser and not stored on our servers unless you explicitly save it as a GitHub gist. For gists, the code is stored on GitHub's servers according to their privacy policy.

Can I run server-side code like PHP or Python?

Client-side languages (HTML, CSS, JavaScript) run directly in your browser. For server-side languages, we use a secure backend execution environment that safely runs your code and returns the output without storing it.

How do I upload my existing code files?

Click the 'Upload File' button or drag and drop files into the upload area. Supported file types include .js, .py, .html, .css, .php, .java, .cpp, and many other common code file extensions.
