The Database Decision
Your database choice affects everything: performance, scalability, development speed.
PostgreSQL: The Default Choice
For 90% of SaaS applications, PostgreSQL is the answer.
Why PostgreSQL?
Serverless Databases
Supabase
Neon
Redis: The Speed Layer
Use it for caching, sessions, rate limiting - not as primary database.
Our Recommendations
Early Stage Startup
Supabase or Neon - Simple, managed, affordable.
Growing SaaS
PostgreSQL (managed) with Redis for caching.
Conclusion
Start with PostgreSQL. Add Redis for caching. Consider specialized databases only when needed.
