Built a booking system with Create.xyz?
We'll make it production-ready.
Booking systems coordinate scarce resources — time slots, rooms, tables, appointments — between providers and customers. A double-booking or a missed confirmation email directly costs you money and trust. AI tools build attractive calendar UIs quickly, but the underlying scheduling logic, timezone handling, and payment integration need to be bulletproof before you take real bookings.
Booking System challenges in Create.xyz apps
Building a booking system with Create.xyz is a great start — but these challenges need attention before launch.
Double-booking prevention
Two customers booking the same time slot simultaneously is the most critical failure mode. AI-generated booking logic often has race conditions — checking availability and creating the booking aren't atomic, so two requests can both see the slot as available and both succeed.
Timezone handling
If your provider is in New York and your customer is in Los Angeles, a '2 PM appointment' means different things. AI tools store times in the server's timezone or the developer's local timezone, causing bookings to appear at wrong times for users in other timezones.
Calendar integration and availability
Providers have existing calendars (Google Calendar, Outlook) that affect their availability. Without two-way calendar sync, providers get double-booked with their personal events, or manual availability management becomes a full-time job.
Payment and cancellation policies
Bookings often require deposits or full prepayment. Cancellation policies (full refund within 24 hours, 50% after that, no refund day-of) need precise time-based logic. AI tools implement basic checkout but not the nuanced refund rules that booking businesses need.
Confirmation and reminder notifications
No-shows kill booking businesses. You need immediate booking confirmations, reminders at 24 hours and 1 hour before, cancellation notifications, and rescheduling flows. AI tools send a confirmation email at best — the full notification pipeline is usually missing.
Recurring bookings and scheduling rules
Weekly appointments, buffer time between bookings, lunch breaks, holidays, and maximum bookings per day are all scheduling rules that AI tools don't implement. Without these constraints, your calendar becomes unmanageable for providers.
Waitlist and cancellation backfill
When a popular time slot opens up due to cancellation, you need to notify waitlisted customers automatically. This turns lost revenue into recovered bookings. AI tools don't build waitlist functionality.
What we check in your Create.xyz booking system
Common Create.xyz issues we fix
Beyond booking system-specific issues, these are Create.xyz patterns we commonly fix.
No authentication — all generated apps are fully public with no user accounts
Create.xyz generates functional applications without any authentication system. Every page, API endpoint, and data resource is accessible to anyone with the URL, making it unsuitable for any application that handles user-specific or private data.
Hardcoded data and mock API responses replace real database or API integration
Generated applications use static JavaScript arrays or hardcoded JSON as data sources. There is no real database integration — data does not persist between sessions, is visible in source code, and resets on every page reload.
No input validation or sanitization on generated form and API handlers
Form submissions and API routes in Create.xyz-generated code process user input directly without validation, type checking, or sanitization, making them vulnerable to injection attacks and malformed data that breaks the application.
Error handling is absent — unhandled exceptions produce blank screens or cryptic errors
Generated application code lacks try/catch blocks, error boundary components, and meaningful error messages. When an API call fails or unexpected input arrives, the application either crashes silently or shows a raw JavaScript error to the user.

Frequently asked questions
Can I build a booking system with Create.xyz?
Create.xyz is a great starting point for a booking system. It handles the initial scaffolding well, but booking systems have specific requirements — double-booking prevention and timezone handling — that need professional attention before launch.
What issues does Create.xyz leave in booking systems?
Common issues include: no authentication — all generated apps are fully public with no user accounts, hardcoded data and mock api responses replace real database or api integration, no input validation or sanitization on generated form and api handlers. For a booking system specifically, these issues are compounded by the need for double-booking prevention.
How do I make my Create.xyz booking system production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Create.xyz-built booking systems, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Create.xyz-built booking system?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger booking system projects, we provide a custom fixed quote after the audit — no hourly billing.
