Can I vibecode YouCanBookMe?

// buildable in a weekend, but real gaps stay open

The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For YouCanBookMe, offer booking pages with availability rules, confirmations, and rescheduling. The hard boundary is calendar integration maturity, forms, reminders, payments, and support, plus calendar integrations and reliability.

Indice: minus 2. think twice

The moat outweighs the price: rebuilding this is a project, not an evening.

Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.

What you build

Read one calendar, publish booking pages with availability rules, create conflict-safe bookings, support rescheduling, and send confirmations and reminders.

what you need

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

The prompt

A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.

One-shot prompt EN
Build a personal replacement for YouCanBookMe in an empty repository.
Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, Google Calendar OAuth, and Resend; do not offer alternative stacks.
The core loop is: read one calendar, publish booking pages with availability rules, create conflict-safe bookings, support rescheduling, and send confirmations and reminders.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Implement one account with configurable working hours, buffers, minimum notice, and booking horizon.
Connect Google Calendar using OAuth and store refresh tokens encrypted at rest.
Calculate availability in UTC and render it in the visitor's detected timezone.
Reserve slots transactionally, create calendar events, and prevent concurrent double booking.
Send confirmation, cancellation, and reminder email with signed management links.
Add an admin booking list, event-type editor, audit log, and calendar reconnect flow.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out Microsoft and Apple calendar support.
Deliberately leave out team round-robin routing.
Deliberately leave out payments, CRM workflows, and enterprise controls.
Finish by running the tests and listing the exact commands used.

What you lose

  • calendar integration maturity, forms, reminders, payments, and support
  • multiple calendar providers
  • team routing and round-robin
  • payments
  • timezone edge-case maturity

Why people still pay

People still pay for YouCanBookMe 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.
