Open WebUI

Open WebUI is a self-hosted platform for running AI models without depending on a vendor's infrastructure. It works with local models via Ollama and cloud providers like OpenAI and Anthropic, all through a single interface. Your data stays where you put it.

It's built for people who want real control. That means no accounts required to get started, no third-party data handling, and no lock-in to a single model provider. It fits as well on a personal laptop as it does inside an enterprise network.

What you can connect and do:

• Model flexibility: Connect Ollama, OpenAI, Anthropic, or any OpenAI-compatible API. Mix local and cloud models in the same workspace.
• Voice, vision, and retrieval: Multimodal capabilities are included out of the box, not bolted on later.
• Python extensions: Write custom tools and functions to extend behavior beyond what the default interface offers.
• Web search integration: Pull live information into conversations without leaving the platform.
• Enterprise controls: SSO, role-based access control, and audit logs for teams operating in regulated environments.

The community platform hosts over 410,000 members sharing prompts, models, tools, and functions. You can install what others have built or publish your own. It's a meaningful accelerator if you're experimenting or building on top of Open WebUI for others.
