Security Posture

DevUI is a development-only sample app, not a production hosting surface. Authentication is enabled by default. Unauthenticated mode is allowed only on localhost / 127.0.0.1; 0.0.0.0, LAN IPs, and hostnames require DEVUI_AUTH_TOKEN or --auth-token.

Import Path

from agent_framework.devui import serve, register_cleanup
# or directly:
from agent_framework_devui import serve
