02Could AI build it for you?

The core job: Read one calendar, publish booking pages with availability, collect optional payments, create conflict-safe bookings, and send confirmations and reminders.

What a working version needs:

Google Calendar OAuth credentials
PostgreSQL
public deploy target
Resend API key
domain with HTTPS

Editorial comparison targets the Pro plan and a single-user booking service DIY substitute. Recheck price before merge.

03What you'd give up

calendar connections, payments, reminders, team access, and hosted reliability
multiple calendar providers
team routing and round-robin
payments
timezone edge-case maturity

People still pay for Zencal because people pay because one double booking or missed invite can cost more than years of subscription fees. The recurring cost buys OAuth refresh, webhooks, timezone databases, race conditions, reminders, deliverability, privacy, and uptime, not just the visible interface.
