Open WebUI

Chat UIsLocal + hybridWeb

Browser chat against any OpenAI-compatible server. Open WebUI is the usual self-hosted pick. The llama.cpp built-in web UI is the zero-extra-process option on :8080.

Fully local (the same toggle as /calculator?usage=local): the box on the desk does the whole job. Prefer a harness that talks to 127.0.0.1 without a vendor proxy.
