Hey Product Hunt 👋 I built Calnode because self-hosted schedulers had gotten heavy -Postgres, Redis, a Node monorepo — just to book a call. Calnode is one static Go binary + SQLite. Drop it on a $5 box (ours runs ~30¢/month) and you've got booking pages, Google/M365/CalDAV sync, an API, an MCP server for AI agents, and optional AI "book by chat" with your own LLM. The part I'm proudest of: Calnode Rooms, built-in video that runs on your own LiveKit with recordings written to your S3 bucket and a self-serve audit kit so you can verify every security claim yourself instead of trusting a report. It's Apache-2.0 and nothing's paywalled. Self-host is the product; a managed-hosting option is on the waitlist. Would love your feedback. I'm here all day. ▶️ Try it live (no signup): https://demo.calnode.com 🔗 https://calnode.com 🔗 https://github.com/Calnode/calnode
