Ollama
Run LLMs on your own computer with a single command — no GPU required for smaller models
A beautiful, feature-rich web interface for Ollama and other LLM backends
Open WebUI is what happens when you want Ollama's local models with a polished ChatGPT-like interface on top. The difference from raw Ollama is night and day — you get user accounts, conversation history, document upload with RAG, and a settings panel that doesn't require a terminal. What impressed us most is how genuinely usable this is for non-technical users. A team member who's never touched a command line can log in and start chatting with documents within minutes. The RAG integration is particularly well done: upload a PDF and ask questions about it without any configuration. That said, you still need Docker comfort to get it running, so it's not quite zero-setup. If you're running Ollama and wish it had a proper UI, this is the answer.
Best for users who are comfortable following setup instructions or running a self-hosted tool.
