Your site should feel instant. We rebuild bottlenecks across rendering, assets, and data flow — so your Next.js app loads faster, scores higher, and converts more.
If your Next.js site is “pretty” but slow — you’re paying for it in lost rankings, lost leads, and lost trust. We optimize where it matters: the actual user experience.
Not “benchmarks on a perfect laptop”. We optimize your app to feel fast on real phones, real networks, real users.
We fix the common Next.js killers: heavy client bundles, blocking data requests, layout shifts, oversized images, and slow server responses.
We optimize the rendering strategy and data flow, not just “minify stuff”.
We decide what belongs on the server, what belongs on the client, and how to cache it safely — so pages load instantly and stay consistent.
We optimize the things users actually download: fonts, images, third-party scripts, and trackers — without breaking your marketing stack.
Fast wins first. Deep wins next. Production-safe always.
We profile bundle size, routes, waterfalls, and Core Web Vitals on real devices.
We rank fixes by impact: speed, SEO, UX, and conversion — not just developer preference.
Rendering strategy, caching, assets, and code splitting — implemented cleanly and tested.
Before/after metrics, Lighthouse + field data, and ongoing guardrails to keep it fast.
SeaOpen turns slow Next.js apps into premium experiences — the kind that feels instant, looks expensive, and performs like a product company built it.
