Common SaaS Questions

Answers to frequently asked questions about SaaS development

Which authentication provider should I use?

For most SaaS applications, we recommend NextAuth.js with OAuth providers like Google, GitHub, or email/password. It provides excellent security and user experience out of the box.

How do I handle multi-tenancy?

Most boilerplates implement row-level security or separate databases per tenant. Choose based on your isolation requirements and scaling needs.

What's the best billing solution?

Stripe is the most popular choice for its comprehensive API and built-in features. Paddle is great for EU compliance and tax handling.

How do I ensure security?

Implement proper authentication, use environment variables for secrets, validate all inputs, and regularly update dependencies. Most boilerplates include security best practices.
