SaaS App challenges we solve
Common saas app issues in apps built with Windsurf or v0.
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.
