Overview
Next.js App Router app with Tailwind that sends a prompt to Llama 3.1 405B on Together AI and renders the generated React app in a sandboxed iframe using esbuild-wasm and esm.sh. Needs TOGETHER_API_KEY, a Postgres DATABASE_URL via Prisma (Neon suggested) and S3 credentials for screenshot uploads; Braintrust tracing is optional. For developers building a prompt-to-app demo on open models.
