How to Choose a SaaS Tech Stack
in 2026
"The wrong stack is a debt you'll pay for years."
TL;DR
Choosing a stack isn't about what's "cool". It's about Speed, Type Safety, and Cost. The 2026 "Golden Stack" is: Next.js + Tailwind + Drizzle + Neon.
Decision Matrix
| Need | Recommended Tool | Avoid |
|---|---|---|
| SEO & Speed | Next.js 15 (App Router) | Create React App |
| Database | Neon (Postgres) | MongoDB (Unless purely JSON) |
| Styling | Tailwind CSS v4 | Styled Components |
