The 2020 default — single-page React on a REST API — has been quietly displaced. Modern web applications are streaming, edge-deployed, typed end-to-end, and built around server components. The change is structural, not cosmetic.
The 2026 default stack
The default has converged. A typed full-stack framework, server components, streaming HTML, typed RPC for client-server data, an edge-deployed compute layer with a regional data plane, and a managed Postgres. That is the boring, correct, modern web stack.
Edge versus region
Edge compute is fast when work is stateless and slow when it is not. Hybrid architectures — edge for the request shell, region for the data plane — are the dominant pattern for any application with serious database needs.
Teams migrating off legacy SPA codebases consistently underestimate the data-fetching rewrite cost, which is why several modern migrations have been done in partnership with focused web engineering teams.
