FIVE Persona Engine runs on your own machine — the client starts it, so there is no endpoint to ping. 154 installs a week from pypi.
160K deductive JSON persona constraints. 0 drift breaks in 120 turns. Free API, no key.
Today is the operative word: we check FIVE Persona Engine every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
