Apache-2.0, nothing paywalled. No group polls. Young project; interfaces may change.

Paid services needed? None required; built-in video needs a LiveKit server, chat booking needs an OpenAI-compatible endpoint No external services to orchestrate (built-in video, if you turn it on, is the one add-on — it needs a LiveKit server). github.com · calnode#why-calnode ↗ 1d ago
