AI code assistant that writes, explains and runs your code

Describe what you want in plain English. Pellux AI generates a working app, executes it live in the preview below, and can promote it to a real isolated sandbox with its own URL when you build it as a project.

Describe the app you want

Open in Projects for a real sandbox

How the sandbox preview works

1. Describe

Write a plain-English request. The assistant plans files, dependencies and structure before writing code.

2. Execute

Single-file apps run instantly in the isolated browser preview above — no install, no server access.

3. Sandbox

Multi-file projects run in an isolated container with a live preview URL, resource limits and automatic cleanup.

Generated code never runs on Pellux AI's servers. Browser previews are sandboxed and project runs happen inside a disposable external container.
