Open WebUI – what is it?

Open WebUI is an open-source web interface for working with large language models that enables interaction with AI via a browser and management of models in local or server environments. The Open WebUI platform integrates with various backends, including local LLMs (e.g., via Ollama) and remote APIs, providing a unified interface for model access, session management, and configuration of inference parameters.

In practical scenarios, Open WebUI is used to deploy internal AI assistants, test models, work with enterprise data, and build isolated environments for interaction with LLMs. The solution supports authentication, query history persistence, integration with RAG systems, and interface customization, allowing it to be adapted to security requirements and operational processes within enterprise infrastructure.
