Understanding Tech Stack Decisions

What Is a Tech Stack?

Simple definition: A tech stack is the collection of technologies you use to build and run your application.

Typical components:

• Frontend: What users see and interact with (React, Next.js, Vue)

• Backend: Server logic and business rules (Flask, Node.js, Supabase)

• Database: Where you store data (PostgreSQL, MongoDB, Firebase)

• Hosting: Where your app runs (Vercel, Netlify, Railway)

• Additional services: Email, payments, authentication, etc.
