How to Choose the Right Tech Stack for Your Startup

I've helped dozens of startups choose their tech stack, and the biggest mistake I see is over-engineering from day one. You don't need Kubernetes for your MVP.

Start with Your Constraints

Before picking technologies, answer these questions:

1. What's your timeline? If you need to launch in 4 weeks, use what you (or your developer) knows best.

2. What's your budget? Some stacks have higher hosting costs than others.

3. Who will maintain this? If you're hiring junior developers later, pick mainstream technologies.

4. What are your scale requirements? Be honest — most startups don't need to handle millions of users on day one.

My Default Recommendation

For most startups, I recommend:

•Frontend: Next.js + TypeScript + Tailwind CSS

•Backend: Node.js + Express (or Next.js API routes)

•Database: PostgreSQL (structured data) or MongoDB (flexible schemas)

•Hosting: Vercel (frontend) + Railway or AWS (backend)

•Auth: NextAuth.js or Clerk

This stack is fast to develop with, easy to hire for, and scales well.

Common Mistakes

Over-engineering: You don't need microservices for an app with 100 users. Start with a monolith.

Trendy tech: That new framework with 500 GitHub stars might not exist in 2 years. Stick with established tools.

Ignoring developer experience: A productive developer on a "boring" stack ships faster than a struggling developer on a cutting-edge one.

When to Reconsider

If your app has specific requirements (real-time collaboration, heavy computation, AI/ML), those should drive your stack decisions. The default stack above works for 80% of startups.
