# Calnode

> Calnode is new (repo created June 2026, v0.11.0 Oct 2026, 118 stars, pre-1.0). One static Go binary with SQLite serves booking pages and an admin app. Documented: Google, Microsoft and CalDAV free/busy, round-robin and collective team routing, Stripe paid bookings, Zoom, HMAC webhooks, a REST API and a built-in MCP server; optional video rooms need a LiveKit server. Apache-2.0, nothing paywalled. No group polls. Young project; interfaces may change.
