React front-ends that score 95+ on Core Web Vitals and survive a pentest. A Next.js development agency for SaaS dashboards, headless storefronts and marketing sites that need to rank.
Next.js is how we ship front-ends that are both fast and indexable: server components, streaming, ISR for content, edge middleware for auth and personalisation. Evosec has built Next.js applications for SaaS products, marketplaces, fintech dashboards and high-traffic marketing sites in France and the United States.
We pair it with Laravel or Node.js APIs, TypeScript end-to-end, and a design-system approach (Tailwind + Radix/shadcn) so your product looks consistent at page 1 and page 100.
App Router, server actions, optimistic UI, real-time updates — complex product UIs that stay maintainable.
Next.js on top of Shopify, Sanity, Strapi, WordPress or a custom Laravel API.
Static + ISR pages, structured data, image/font optimisation, 95+ Lighthouse — engineered for SEO from day one.
Tailwind CSS, Radix/shadcn, Storybook — accessible components your team can reuse.
NextAuth/Auth.js or your IdP, CSP headers, SSRF-safe server actions, dependency audits, and a front-end pentest before launch.
Vercel or AWS, preview environments per PR, edge caching, monitoring and error tracking.
Next.js when SEO, performance or server rendering matters — almost always for customer-facing products. Vite + React for purely internal tools behind a login.
Yes. We regularly put a Next.js front-end on an existing Laravel, Django, Rails or .NET API.
Strict CSP, server-only secrets, validated server actions, dependency scanning in CI and a manual pentest of the release candidate by our security team.
Yes — senior React/Next.js engineers on retainer, CET hours with US East Coast overlap.
