Open WebUI is a self-hosted graphical user interface for interacting with artificial intelligence models, particularly large language models. It can be used as a browser-based interface for locally hosted models through software such as Ollama and for remote models provided through OpenAI-compatible application programming interfaces (APIs).[2][3]
When used with locally hosted models, Open WebUI can operate entirely offline, while remotely hosted models can be accessed over the Internet through third-party providers. It provides a ChatGPT-style interface while allowing users to select among different models and providers.[4]
History
[edit]Open WebUI was created by Timothy J. Baek in 2023 and was originally named Ollama WebUI. The project initially served as a web interface for Ollama before expanding to support additional model providers and APIs. It was renamed Open WebUI in February 2024 to reflect its broader scope.[5]
Features
[edit]Open WebUI provides a web-based chat interface that can connect to Ollama and services implementing an OpenAI-compatible API. Users can interact with multiple models from the same interface and deploy the software using methods including Docker, Kubernetes, or Python.[6][7]
The software includes support for retrieval-augmented generation (RAG) using uploaded documents and knowledge bases. Other features include web search, image generation, voice interaction, model tools and external extensions.[8]
Open WebUI can connect to external tools and services through mechanisms including OpenAPI servers and the Model Context Protocol (MCP). It also supports Python-based tools that execute within an Open WebUI installation.[9]
Open WebUI is primarily used with locally hosted large language models, but it can also access models hosted by third-party providers through compatible APIs.[10]
Security
[edit]In 2025, a vulnerability in Open WebUI's Direct Connections feature, designated CVE-2025-64496, was disclosed. The vulnerability could allow malicious model servers to execute JavaScript in a user's browser and potentially lead to account takeover or remote code execution when combined with other functionality. It affected version 0.6.34 and earlier and was patched in version 0.6.35.[11]
