Why We Chose Next.js 15 & Drizzle ORM for Enterprise SaaS

Choosing a tech stack is a bet on the future. At Saarza, we bet heavily on Next.js 15 (App Router) and Drizzle ORM.

Here is why this combination is unbeatable for modern SaaS.

1. Zero-API Boilerplate (Server Actions)

In the past, fetching data meant:

1. Create API route
2. Fetch in Client
3. Handle Loading/Error states

With Next.js 15 Server Actions, we simply write a function and call it directly from our frontend components. It's fully type-safe and eliminates 50% of the code.

2. Drizzle vs. Prisma

We migrated from Prisma to Drizzle for one main reason: Cold Start Performance.

Prisma ships a heavy Rust binary that slows down serverless functions. Drizzle is lightweight, SQL-like, and runs purely in TypeScript. Our database queries went from ~300ms to ~50ms.

3. Edge Compatibility

This stack runs perfectly on the Edge. Whether your users are in Mumbai or New York, your SaaS loads instantly.

Conclusion

If you are starting a SaaS today, don't overcomplicate it. Type-safety + Server Components = Speed.
