Open WebUI
Open WebUI is the most popular self-hosted AI interface, an extensible workspace that teams run on their own infrastructure, offline if needed. It connects to OpenAI-compatible APIs out of the box: add a connection with a base URL and key and the models behind it appear for your users. Connect Opper and one admin setting gives your whole deployment 700+ models, with a choice of EU or US inference behind your own walls.
