02Could AI build it for you?

The core job: Read one calendar, publish booking pages with availability, routing rules, and forms, 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 Schedule plan and a single-user booking service DIY substitute. Recheck price before merge.

03What you'd give up

routing depth, calendar integrations, CRM workflows, and dependable scheduling
multiple calendar providers
team routing and round-robin
payments
timezone edge-case maturity

People still pay for OnceHub 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.
