What RSC actually changes about how you structure an app, and where it doesn't matter.
Data-heavy components render on the server; only interactive parts ship to the browser. Faster loads, better SEO.
Fetch where you render. Fewer loading spinners and waterfalls, simpler state.
Highly interactive dashboards still need client components. Mix deliberately.
The web stack keeps evolving — React Server Components, stricter Core Web Vitals, headless CMSs, AI-driven interfaces — but the goals are constant: fast, accessible, discoverable, maintainable. This article explains how we make those decisions on client projects and what actually moves performance and rankings in 2026.
| Core Web Vital | Threshold (good) | Most common fix |
|---|---|---|
| LCP | ≤ 2.5s | Server rendering, image optimisation, preload hero asset |
| INP | ≤ 200ms | Break up long tasks, defer third-party scripts |
| CLS | ≤ 0.1 | Reserve space for images, ads, and fonts |
We are an AI-first development company that designs, builds, and operates AI agents, LLM-powered applications, and AI-native web and Flutter mobile products. Every engagement starts with a free discovery call where we map your process, assess your data, and give you a fixed-scope plan with a timeline and estimate — including projected running costs. From there we ship weekly, measure against an evaluation set, and support your product after launch.
