Since 2008, we have delivered over 1,000 web projects — from high-traffic SaaS platforms to enterprise portals to e-commerce storefronts. Whether you need to migrate a legacy app, build a new product from scratch, or scale an existing Next.js codebase, our team ships fast, maintainable code with full TypeScript, automated testing, and CI/CD from day one.

Frequently asked questions

How much does Next.js development cost?

Next.js project pricing depends on complexity and team size. Small marketing sites or MVPs typically range from $15,000 to $40,000. Mid-sized SaaS applications range from $60,000 to $200,000. Enterprise platforms and complex migrations start at $150,000 and can exceed $500,000. We offer fixed-price, time-and-materials, and dedicated-team engagement models.

How long does it take to build a Next.js application?

A simple marketing site can launch in 4-6 weeks. A production SaaS MVP typically takes 10-16 weeks. Enterprise applications with complex integrations range from 4 to 9 months. We ship a working staging environment within the first 2-3 weeks of every engagement.

Do you work with the Next.js App Router or Pages Router?

All new projects use the App Router, which is the recommended approach from Vercel as of 2024. We actively migrate Pages Router projects to App Router when clients want the benefits of React Server Components and improved performance. For existing Pages Router projects with no migration need, we are equally comfortable maintaining and extending them.

Can you migrate our existing React app to Next.js?

Yes. We have migrated dozens of Create React App, Vite, Gatsby, and legacy PHP/WordPress sites to Next.js. Every migration includes an SEO-safe redirect map to preserve rankings, a phased rollout plan, and thorough before/after performance benchmarking.

Where are your developers based?

Our client-facing team — project managers, architects, and solutions leads — is based in our Toronto, Canada headquarters. Our full-time engineering team works from our Mirpur DOHS office in Dhaka, Bangladesh. All work is managed through Toronto-based accountability with real-time communication during North American business hours.

Do you host the Next.js apps you build?

We recommend and set up Vercel, AWS, or Cloudflare deployment depending on the project. We can manage ongoing hosting and DevOps as part of a retainer, or hand off cleanly to your internal team with full documentation.
