Why Increasio is Your Ideal Next.js Partner

Why Increasio is Your Ideal Next.js Partner

As a Vercel partner, we have experience with Next.js 16, App Router, and Server Components that has been tested in production. Our team builds fast, secure, and scalable apps that meet measurable business goals like conversion rate, Core Web Vitals, and time-to-market. We do everything from website and application development to enterprise headless CMS integrations to headless commerce on the Storefront API.

What is Next.js 16?

Next.js is the leading React framework for production, maintained by Vercel. Next.js 16 ships with Turbopack as the default bundler, stable App Router with React Server Components, and Partial Prerendering (PPR) that combines static and dynamic rendering in a single response. Increasio builds on the full Next.js 16 feature set - App Router, Server Actions, Edge runtime, ISR, and PPR - to deliver applications that are fast to load, cheap to run, and ready to scale from day one.

Why Next.js?

Next.js is the open-source React framework from Vercel. It adapts to every project size, from a marketing site to a multi-tenant SaaS, and lets us choose the right rendering strategy per route - static, server-rendered, or partially prerendered. Talk to us and we will show you why Next.js 16 fits your next build.

Turbopack Performance

Next.js 16 ships with Turbopack by default. Up to 10x faster local dev and incremental builds measured in seconds, not minutes.

Security by default

Server Actions, HTTP-only cookies, and CSP-ready headers. We apply OWASP standards from day one so sensitive data stays protected.

Design-led engineering

We pair Figma-ready design systems with Server Components and Tailwind so the UI we ship matches the UI you designed, pixel for pixel.

Compatibility

Next.js slots into any backend, CMS, or auth provider. We integrate with Hygraph, Sanity, Payload, Strapi, Shopify, and custom APIs.

App Router architecture

We structure every project around App Router, Server Components, and route groups so scaling up or handing off to your team is painless.

SEO-friendly

Metadata API, structured data, sitemaps, and PPR for Core Web Vitals. Our Next.js builds target green PageSpeed on every route.
More conversions, better performance

Core Web Vitals - all green

More conversions, better performance

Next.js 16 with PPR and Turbopack consistently lands LCP under 1.5s and CLS near zero on our production builds. Case in point: our Starlight project ships a fully dynamic marketing site with a static-like LCP and 100 on Lighthouse mobile. Faster pages convert better - across our portfolio, we see 15-30% uplift in primary conversions after migrating legacy stacks to Next.js.
SSG, SSR, ISR, and Partial Prerendering

The right rendering, per route

SSG, SSR, ISR, and Partial Prerendering

Next.js 16 lets us mix rendering strategies inside one app. Marketing pages render statically. Authenticated dashboards stream via Server Components. Product pages use ISR to revalidate on demand. PPR combines a static shell with dynamic holes in a single response. We pick the right mode per route so you never pay for rendering you do not need.

How we deliver Next.js projects

Every engagement follows the same four-stage process, refined across 120+ Next.js builds. 1. Scope & estimate (48 hours). You send a brief, we return a fixed-scope estimate with timeline, tech choices, and team allocation. 2. Design & architecture (1-2 weeks). Figma design system, App Router route map, data model, and CMS schema agreed before a single component ships. 3. Build & ship (4-16 weeks). Weekly demos on a live Vercel preview. Server Components, Server Actions, and PPR applied where they actually help - no over-engineering. AI-assisted workflows let us move faster on repeatable surfaces without compromising code quality. 4. Launch & support. Production deploy on Vercel with monitoring, Core Web Vitals budgets, and a monthly or hourly retainer for continuous development. Explore all our services or meet the team.

FAQs for Next.js Development

Common questions about building with Next.js 16 and the services we provide. Don't see your question? Send us a message.
  • What is Next.js 16 used for?

    Next.js 16 is a production React framework for marketing sites, SaaS dashboards, ecommerce storefronts, and enterprise web apps. It supports App Router, Server Components, Server Actions, Turbopack, and Partial Prerendering, making it a fit for everything from a fast landing page to a multi-tenant application.
  • How much does it cost to build an app in Next.js?

    Cost depends on scope, design complexity, and integrations. With AI-assisted design and development, a Next.js 16 marketing website can start from $4k. Production web applications and enterprise builds scale from there. Send us a brief and we will return a fixed-scope estimate within 48 hours.
  • How long does it take to build a Next.js website?

    A Next.js 16 marketing or content site typically ships in 4-10 weeks. A full web application takes 3-6 months, depending on integrations, auth, and custom features. We can run in parallel phases to start serving users before the full scope is delivered.
  • Do you support and maintain Next.js websites after launch?

    Yes. We offer two support plans - a fixed monthly retainer for continuous development and an hourly plan for ad-hoc work. Both include Next.js and dependency upgrades, security patches, and performance monitoring.
  • Do you work with Next.js 16 and App Router?

    App Router is our default for every new project. We have migrated multiple production codebases from Pages Router to App Router and can scope a migration for your team. See our Jamstack and enterprise CMS work for examples.
  • Is Turbopack ready for production in Next.js 16?

    Yes. Turbopack is the default bundler in Next.js 16 for both dev and production builds. We have shipped it across client projects and consistently see build times drop 5-10x versus Webpack, with no runtime regressions.
  • Are you a Vercel partner?

    Yes. Increasio is an official Vercel partner, which means direct escalation paths, early access to Next.js features, and deployment expertise on Vercel's Edge and Fluid Compute infrastructure.
