Daniel-debug-boop/Wren ? reverse-engineered prompt

Build me a self hosted AI engineering app called Wren that runs on my own machine or server and keeps code and data private.

I want a web app with a polished coding workspace, including a code editor, a file browser, an integrated terminal, and an AI chat panel. It should let me connect my own LLM provider, use different models for different tasks, and have agent style workflows for things like debugging, refactoring, code review, and testing. I also want a simple way to run actions in a sandbox so risky code stays isolated.

Please make it easy to start locally with one command, and make sure the frontend and backend work together cleanly. Use the existing project structure if it helps, and if you need current setup details for any library or integration, look them up online. The end result should feel like a real product I can open in the browser and use to work on code with AI.
