I recently built a working AI app builder from scratch using Next.js, AWS S3, and Tensorlake Sandboxes. You can describe an app in plain English, and the AI writes the code, runs it in an isolated sandbox, fixes errors, and gives you a live preview. It also supports version history and publishing. I wrote a detailed tutorial on freeCodeCamp covering the architecture, agent loop, sandbox setup, and the actual implementation Here's the full walkthrough with source code published on freeCodeCamp. https://www.freecodecamp.org/news/build-your-own-ai-app-builder-with-next-js-aws-and-sandboxes/ Would love to hear what you'd do differently, especially around sandboxing and running AI-generated code safely.   submitted by   /u/latentnoise_ [link]   [comments]
