Overview

Open WebUI is a Python-served web interface (pip or Docker, port 8080) for Ollama and any OpenAI-compatible API such as LM Studio, vLLM, OpenRouter or Groq. It bundles RAG over 9 vector databases with hybrid BM25 search, web search through 20+ providers, image generation via ComfyUI, AUTOMATIC1111, DALL-E or Gemini, MCP and OpenAPI tool servers, and per-user roles with LDAP, OAuth and SCIM provisioning.

Who it is for: Teams and homelabs wanting a multi-user front end for local models

Strengths

  • Images tagged :ollama and :cuda bundle Ollama or CUDA acceleration in one container
  • RBAC, user groups, LDAP/AD, OAuth SSO and SCIM 2.0 provisioning built in
  • 9 vector databases incl. ChromaDB, PGVector, Qdrant, Milvus and Elasticsearch
  • Redis-backed sessions and WebSockets for multi-worker, multi-node deployments

Weaknesses

  • Custom Open WebUI License requires keeping the Open WebUI branding visible
  • Enterprise plan pitched at the top of the README; Terminals isolation is enterprise-only
  • pip install is pinned to Python 3.11
  • Data is lost unless the /app/backend/data volume is mounted

What it needs

  • GPU optional
  • Docker + Compose
  • Models: Ollama, OpenAI-compatible APIs, LM Studio, vLLM, OpenRouter
  • port 8080
