Open-WebUI

Self-Hosted

Open-source, self-hosted frontend for LLMs (local & remote)

Overview

Open-WebUI is an open-source, self-hosted frontend for interacting with large language models (LLMs). It offers an intuitive chat interface with markdown support, model switching, and customizable prompt templates. Deployable via Docker (one-line command), Kubernetes, or direct installation, it integrates with local LLMs (Ollama, LlamaCpp) and remote APIs (OpenAI, Anthropic). Ideal for privacy-conscious users, it lets you control your data while accessing both local and cloud-based models, supporting multiple users and extensions.
