Overview

Open WebUI is a locally deployed chat tool that users access through a browser and connect to backend services such as Ollama to run models. It supports features such as multi-model switching, conversation history management, and file uploads, making it suitable for developers to set up on personal devices or servers. Unlike cloud-based chat services, it requires users to manage model downloads and runtime environments themselves, with an emphasis on keeping data local.
