The modern web stack of 2026 is unrecognisable from 2020. Edge runtimes are the default. Server components have killed half the state-management library ecosystem. TypeScript end-to-end is table stakes. And the gap between a Vercel-deployed Next.js app and a hand-rolled Express monolith has never been wider in terms of operational cost.
Edge by default
Most pages do not need a long-lived Node process. Workers and edge functions, with a fast database in-region, win on latency, cost and operational simplicity.
Server components, used judiciously
React Server Components are powerful and easy to misuse. Treat the client/server boundary as an architectural decision, not an annotation.
Picking a partner
A modern web and mobile app development company brings opinions on stack, hosting and observability that compound over Year 2 and Year 3. Choose accordingly.
