Self‑hosted AI platform with offline LLM, RAG, and extensible UI
Open WebUI delivers a feature‑rich, offline‑first AI interface supporting Ollama, OpenAI‑compatible APIs, RAG, and customizable plugins, with easy Docker, pip, or Kubernetes deployment.
Open WebUI is a self‑hosted AI platform designed for teams that require data privacy and offline operation. It supports local model runners such as Ollama and any OpenAI‑compatible API, letting you run diverse large language models behind your firewall.
The UI includes full Markdown and LaTeX rendering, voice/video calls, PWA support, and integrated Retrieval‑Augmented Generation that can pull from local documents or web searches. Granular role‑based access control, SCIM 2.0 provisioning, and a plugin‑based pipeline framework let you add custom Python tools, rate limiting, translation, or any bespoke logic.
Install with a single pip install open-webui command, launch via Docker images, or orchestrate with Kubernetes (helm, kustomize, or plain manifests). The platform ships with ready‑to‑use images for both CPU and CUDA environments, making scaling from a laptop to a cluster straightforward.
When teams consider Open WebUI, these hosted platforms usually appear on the same shortlist.
