Choosing the Right Tech Stack for Your Web App

Stack decisions get treated like technology choices, but they're really longevity decisions. The question isn't "what's capable of building this" — almost any modern stack is. It's "what will still be maintainable, hireable-for, and boring in three years."

Start from your actual constraints: expected traffic and scale, the skills already on your team or easy to hire for, and how the app needs to integrate with what you already run. A stack chosen for a hypothetical future scale you may never reach usually costs more than the problem it solves.

Favor proven, well-documented technology over the newest option, especially for anything load-bearing — authentication, payments, data storage. Novelty is fine at the edges of a system; it's expensive at the core.

We default to a small set of technologies we can stand behind for the long run rather than picking a new stack per project — consistency here is what makes a system maintainable after the people who built it move on to other work.
