Next.js Development Agency App Router specialists

We build exclusively with the Next.js App Router — React Server Components, Streaming, Suspense boundaries and parallel routes. No legacy Pages Router projects. Your application uses the full power of modern Next.js.

ISR, full-route caching and image optimisation are built in from day one. Our Next.js applications consistently achieve LCP under 1 second and Lighthouse scores above 95 — deployed on EU-based infrastructure.

100% TypeScript across the entire stack — from API routes to UI components. Strict type safety, comprehensive code documentation and zero runtime type errors in production.

We pair Next.js with Payload CMS for content management. Type-safe content models, direct database queries, no REST/GraphQL overhead. The fastest possible headless CMS integration for Next.js.

Unit tests with Vitest, integration tests and E2E tests with Playwright. Every project ships with CI/CD pipelines on GitHub Actions. Nothing reaches production without passing the test suite.

Next.js API Routes and Server Actions for backend logic. We build RESTful and type-safe server integrations — connected to PostgreSQL, Redis, external APIs or your existing backend systems.
