Open WebUI
A feature-complete ChatGPT-style interface for your local LLMs — multi-model chat, document RAG, conversation history, and team management. Fully self-hosted.
Overview
Open WebUI is a self-hosted, feature-rich web interface for running LLMs locally — giving you a ChatGPT-like experience on top of Ollama, LM Studio, or any OpenAI-compatible backend running on your own machine or server. Where Ollama and LM Studio focus on running models, Open WebUI focuses on the conversation experience: it adds multi-model conversations, RAG from uploaded documents, web search integration, conversation history, and user management for team deployments. Privacy-focused teams, enterprises with data restrictions, and developers who want full control over their AI environment use it as a private ChatGPT replacement. Free and open-source.
