Open WebUI

Open WebUI is an open-source, self-hosted AI platform designed to run entirely offline, giving teams a user-friendly interface over multiple LLM backends instead of depending on a single hosted provider. It supports Ollama and OpenAI-compatible APIs as model runners, with a built-in inference engine for retrieval-augmented generation (RAG). Setup runs via pip, uv, Docker, or Kubernetes (kubectl, kustomize, or Helm), with dedicated :ollama and :cuda container images. An optional Enterprise plan adds custom theming and branding, SLA support, and Long-Term Support (LTS) releases for organizations that need more than the community edition.
