Description
Open WebUI runs entirely offline as a Progressive Web App and connects both to local Ollama models and to any OpenAI-compatible API. A built-in model builder lets you create your own model variants based on existing Ollama models, alongside local Retrieval Augmented Generation across several vector databases, and voice and video calls with various speech-to-text and text-to-speech integrations. Installation runs via pip, Docker or Kubernetes, with dedicated images for Ollama and CUDA setups.
For enterprises, Open WebUI brings single sign-on, role-based access control, audit logs, and on-premises or air-gapped deployments for regulated industries. The feature set is correspondingly large, which can mean more effort in setup and maintenance than with leaner alternatives, and operation rests entirely with your own team.
Open WebUI and LibreChat occupy a similar space. Open WebUI is more closely tied to local Ollama workflows and offline operation, and the choice between the two usually comes down to the preferred model infrastructure.
