Built a saas app with Cursor?
We'll make it production-ready.
SaaS apps have the highest stakes for code quality — your users trust you with their data, they pay you monthly, and downtime costs you revenue. AI tools can build a SaaS prototype in hours, but the gap between prototype and production-grade SaaS is significant: subscription billing, multi-tenancy, data security, and reliability all need to be rock-solid.
SaaS App challenges in Cursor apps
Building a saas app with Cursor is a great start — but these challenges need attention before launch.
Subscription billing complexity
AI tools generate basic Stripe checkout but miss webhook handling, failed payment recovery, plan upgrades/downgrades, proration, and subscription lifecycle management. Your billing needs to be bulletproof — incorrect charges destroy trust instantly.
Multi-tenant data isolation
Every user's data must be completely isolated. AI-generated code often stores data without proper user scoping, meaning one customer could potentially see another's data. This is a deal-breaker for any business customer.
Authentication and authorization
SaaS needs more than login/signup. You need team management, role-based access control, API key management, SSO for enterprise customers, and secure session handling. AI tools handle basic auth but rarely implement authorization properly.
Uptime and reliability
Paying customers expect your app to work. You need error tracking, monitoring, graceful degradation, database backups, and an incident response plan. AI-generated apps crash ungracefully and have no observability.
Onboarding and retention
The signup-to-value flow must be smooth. AI tools build the feature but not the experience — missing loading states, unclear error messages, and broken edge cases in onboarding flows cause immediate churn.
Scalability
Your app works with 10 users but will it work with 10,000? Database queries without pagination or indexes, in-memory data processing, and missing caching all cause performance degradation as you grow.
What we check in your Cursor saas app
Common Cursor issues we fix
Beyond saas app-specific issues, these are Cursor patterns we commonly fix.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.

Frequently asked questions
Can I build a saas app with Cursor?
Cursor is a great starting point for a saas app. It handles the initial scaffolding well, but saas app apps have specific requirements — subscription billing complexity and multi-tenant data isolation — that need professional attention before launch.
What issues does Cursor leave in saas app apps?
Common issues include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. For a saas app specifically, these issues are compounded by the need for subscription billing complexity.
How do I make my Cursor saas app production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Cursor-built saas app apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
