LibreChat
LibreChat is the leading open-source AI chat platform, a self-hosted ChatGPT alternative with multi-model chat, agents, file handling, and search. Custom endpoints are a headline feature: one block in librechat.yaml adds any OpenAI-compatible provider. Point it at Opper and your whole workspace chats across 700+ models on one key, with a choice of EU or US inference behind it.
