About Open WebUI
Open WebUI is a self hosted, open source AI interface that unifies access to local and cloud based large language models. It runs entirely in a web browser and supports Ollama for local model hosting alongside any OpenAI compatible API, including services like LMStudio, GroqCloud, Mistral, and OpenRouter. Built in Python, it functions as a drop in replacement for proprietary AI platforms, giving users full control over their model infrastructure and data.
