Ollama + Open WebUI

A complete local LLM runtime (Ollama) paired with a ChatGPT-like web UI (Open WebUI). Supports dozens of open-source models (Llama 3, Mistral, Phi, Gemma, etc.) running entirely on your own hardware — no API keys, no cloud dependency. Ideal for privacy-conscious users and developers who want a self-hosted AI chat experience.

mkdir ollama-open-webui
cd ollama-open-webui
# create docker-compose.yml
# create .env
docker compose up -d
