A real public API + native AI
Caledee ships a REST API, OAuth 2.0, outbound webhooks and a native MCP server — so you can wire scheduling into your CRM, your product, or an AI agent. zcal doesn't publish an API; you're limited to Zapier.
zcal is a polished, design-led scheduler with a strong free tier. Caledee is for people who outgrow that — who need to plug scheduling into their own systems, charge at booking, and host in the EU without giving up the calm, clean booking page.

— Where Caledee pulls ahead
Get paid at booking
Charge invitees with Stripe at booking time — full price or a deposit — with 0% Caledee commission on paid plans, just like zcal. The difference: deposits and routing forms, which zcal doesn't have.
European hosting you can point to
Caledee runs on a European VPS in Paris, GDPR-native, with full data export any time. If where your data lives matters to your buyers, that's a claim you can make precisely.
A waitlist that recovers no-shows
When a slot is full, invitees join a waitlist and the next person is invited automatically the moment one opens — with a claim deadline. It turns a dead end into a recovered booking.
