AI coding tools can help you build a SaaS application surprisingly quickly.
You can generate the frontend, backend, authentication, dashboards, and even parts of the business logic. But most real SaaS applications eventually need somewhere to store data. That's where a production database comes in.
What Does Your SaaS Need to Store?
Think about what your application needs to remember. For example: User accounts Subscription information Orders Projects Messages Application settings Analytics data
If the information needs to survive a restart or deployment, it usually needs persistent storage.
PostgreSQL Is a Common Choice
For many SaaS applications, PostgreSQL is a practical starting point. It works well for structured application data and supports relationships between different types of records. Your AI-generated application may already expect PostgreSQL through an ORM or database library.
Connect Through Environment Variables
Database credentials should not be hardcoded into the source code. Instead, use environment variables such as a database connection string.
Your production application can then connect to the database without exposing credentials inside GitHub.
Deploy the SaaS
With Hostwares, you can deploy the application and configure supporting services for the production environment. The important part is to treat your AI-generated application as a real production system—not just a generated codebase.
