What is a tech stack, and how do you choose one?

A tech stack is the set of technologies a product is built with: the language, framework, database, and hosting. Choose based on what you're building, your team's skills, the ecosystem's maturity, and the ability to hire people who know it, not on what's newest or most talked about.

A common web stack in 2026 pairs a JavaScript or TypeScript framework (like Next.js) with a database and a cloud host. But the right stack is the one that fits your problem and team, and there are many sensible combinations.

The biggest risks are picking something obscure that's hard to hire for, or chasing a trendy tool that isn't proven. Favor mainstream, well-supported technologies unless you have a specific reason not to, so you can maintain and staff the project for years.
