The full deployment path for a Python agent, from local uv run to Docker to a public API on Cloudflare Containers: the Worker enforces authentication, the Container runs FastAPI, secrets never enter the image, and the service sleeps automatically after 10 idle minutes—the right way for a side project to save money.
The main backend runs on a remote HTTPS server, so the auth_token cookie is scoped to that domain. The browser never sends it to the local AI backend, causing the API to treat every request as unauthenticated.
LLM Council is a local Web App Andrej Karpathy built over a weekend. It sends one question to multiple LLMs simultaneously, has them anonymously peer-review each other, and then a Chairman model synthesizes a final answer. Positioned as a small tool for comparing models while studying — 99% vibe coded with no plans for long-term maintenance — but the architecture itself is a minimal ensemble LLM implementation worth studying.
FastAPI is a modern Python web framework built on type hints — it auto-generates OpenAPI docs, supports native async, and delivers performance close to Node.js. It's the top choice for AI/ML services and the most worthwhile framework to learn in the Python backend ecosystem.
Next.js + Expo frontend, Node.js + Python dual backend, PostgreSQL + Redis core — plus a social notification system and LLM recommendation engine. Here's how DaoDao builds a learning community platform with a modern tech stack.
