A local LLM setup in 2026 is a three-layer stack: Ollama (177,825 stars, MIT) downloads and runs models, Open WebUI (147,900 stars) gives you a ChatGPT-like interface, and LocalAI (48,248 stars, MIT) serves an OpenAI-compatible API for existing apps. Everything runs on your machine - private, free, no subscriptions.
