NEXT.JS
Full-Stack React Applications, Rendered for Speed
FrontIT delivers next js development services that bring together the best of React and server-side rendering in a single, production-ready framework. Our 70+ engineers in Vilnius have been building software for over 20 years, and we use that experience to help Europeann businesses launch fast, SEO-friendly applications without compromising on interactivity. Next.js gives us the tools to render pages on the server, cache them at the edge, and hydrate them on the client, all within one unified project.
WHY NEXT.JS
01
Traditional single-page apps leave search engines and slow networks behind. Next.js solves this by rendering initial HTML on the server and handing off to React on the client. The result is pages that load fast and feel interactive immediately. This hybrid approach is central to every next js application development project we take on.
02
Image optimisation, font loading, script prioritisation, and automatic code splitting come out of the box. These features save weeks of manual tuning and ensure that performance best practices are baked into your product from day one. Our next js engineering services leverage every one of these capabilities to deliver measurably faster experiences.
03
With API routes, server actions, and middleware, Next.js can handle backend logic without a separate server process. This simplifies architecture and reduces operational overhead, making it an excellent foundation for server side rendered react development projects that need both a rich frontend and lightweight backend.
WHAT WE BUILD
01
Static generation and incremental static regeneration let us build content-heavy sites that serve pages from a CDN while still updating content without a full rebuild. Our next js web development services include headless CMS integrations with Contentful, Sanity, and Storyblok, giving editorial teams control without sacrificing performance.
02
Multi-tenant SaaS products demand flexible routing, robust authentication, and a fast first-paint. We build these platforms on Next.js with role-based middleware, dynamic subdomains, and shared component libraries. Our custom next js development work ensures each tenant gets a tailored experience powered by a single, maintainable codebase.
03
Product pages that rank well, cart interactions that feel instant, and checkout flows that convert are all possible with Next.js. We integrate with Shopify, commercetools, and custom backends to deliver storefronts where every next js frontend development decision is guided by measurable business outcomes.
04
Server components make it straightforward to fetch and render sensitive data without exposing API endpoints to the browser. We use this pattern to build secure, data-dense dashboards for enterprise next js development clients who need operational visibility without security trade-offs.
EXPERTISE
01
We adopted the App Router early and have production experience with React Server Components, streaming, and suspense boundaries. As a next js development company, we stay ahead of the framework's evolution so our clients benefit from the latest features without bearing the risk of early adoption.
02
We deploy Next.js applications to Vercel, AWS Lambda at Edge, and Cloudflare Workers. Choosing the right deployment target affects latency, cost, and cold-start behaviour. Our next js software development company experience helps clients pick the platform that aligns with their operational requirements.
03
Middleware-based auth, OAuth providers, and session management are areas where we have deep experience. We implement secure flows using NextAuth.js, Clerk, or custom solutions depending on the project's needs. Custom next js solutions from FrontIT always treat security as a foundational layer, not an afterthought.
04
Serving multiple markets means supporting multiple languages and locales. We set up Next.js i18n routing, integrate translation management tools, and handle locale-specific content strategies. Our next js coding services ensure that every locale gets the same performance and user experience as the primary market.
INTEGRATION & MIGRATION
01
Moving from Create React App or Gatsby to Next.js unlocks server rendering, better routing, and improved build performance. We plan and execute these migrations incrementally, keeping your application live throughout the process. When you hire next js developers from FrontIT, you get a team that has completed multiple migrations without user-facing downtime.
02
Next.js works with any backend. We connect it to REST APIs, GraphQL endpoints, and legacy SOAP services, always creating typed client layers that make integration safe and predictable. As a reliable next js development agency, we have built data layers that bridge modern frontends with decades-old enterprise systems.
WHY FRONTIT
01
We understand the regulatory landscape, the cultural norms, and the high standards expected in European markets. keeping things direct and transparent.
02
From technical discovery through to post-launch support, our teams take full ownership of delivery. We do not hand off half-finished work. Every milestone is demonstrated, reviewed, and signed off before we move forward.
SUPPORT
01
Next.js releases new versions regularly, and each update brings performance improvements and new features. Our support contracts include framework upgrades, security patches, and performance reviews. We treat every application as a living product that deserves continuous attention, not a project that ends at launch.
