What shall we build?

Describe an app, a game, a website or a script. Coder writes the files, runs them in the preview and fixes errors. You can also upload or paste your code to have it checked.

Runs in the preview: HTML, CSS, JavaScript, TypeScript, React and Python. Other languages (Java, C, C#, Go, Rust, PHP, SQL…) can be written, explained and checked.

AI can make mistakes. Test the code before you use it; never put passwords or API keys into frontend code.
