Open WebUI is already a free, self-hosted, open-source (BSD-3-Clause) interface for local AI models. People comparing it against other tools are typically evaluating which self-hosted chat front end best fits their model setup and workflow.
If you want a desktop-native client instead of a browser-based interface, Cherry Studio is the closer match. LobeChat is a strong alternative with a bigger plugin ecosystem, while AnythingLLM is the better pick if chatting with your own documents is the main use case, and Jan if you want the simplest possible offline, single-app setup.
