Building Fast Web Apps in 2026
How we ship production-grade web apps that load instantly and scale — the stack, the trade-offs, and the habits behind it.
Why speed is a feature
Users decide whether to trust a product in the first few hundred milliseconds. A fast app feels reliable; a slow one feels broken even when it works.
The stack we reach for
We default to Next.js on the App Router with React Server Components, edge-cached static routes, and a thin client. Most pages ship almost no JavaScript.
Measure, then optimise
Don't guess. Profile real navigations, watch the Core Web Vitals, and fix the largest contentful paint before anything else.
What this means for you
A faster site converts better and ranks better. That is the whole game.
