// EDITOR'S TAKE
Open WebUI and LibreChat come closest to the Claude experience, but both are front ends rather than models: Open WebUI is the most polished for self-hosting against Ollama or an API key, while LibreChat handles multiple providers, agents and enterprise login better. Jan is the one to pick if you want everything offline on your own hardware, accepting that the local models you can run are well short of Claude.
