Next.js Development for scaling companies
Next.js development for sites that do more than publish
We design and build web applications and content-driven sites with Next.js. Front-end, CMS, hosting, and integrations handled as one system, from a single experienced partner.
When Next.js is the right choice
Next.js shines when your site needs to do more than publish content. If you need dynamic functionality alongside marketing pages, this is the framework.
Your marketing site needs a customer portal, a pricing calculator, a search experience, or gated content. Next.js handles the static marketing pages and the dynamic features in a single codebase.
You need to serve different content based on user role, geography, or account status. Next.js server-side rendering lets you personalize pages without sacrificing performance or SEO.
Your site pulls from multiple APIs, databases, or services at render time. Next.js gives you server-side data fetching with fine-grained control over caching and revalidation.
Your team already works in React, or your site needs to share components with a React-based product. Next.js builds on React rather than introducing a new component model.
How we build with Next.js
We don’t just write React components. We design the content model, rendering strategy, and data architecture as one system. The decisions that matter most happen before any UI code gets written.
Next.js supports static generation, server-side rendering, and client-side rendering — sometimes all on the same site. We choose the right approach per page based on how often content changes, whether personalization is needed, and what performance tradeoffs are acceptable.
Most Next.js marketing sites are paired with a headless CMS. We design the content model and CMS editing experience alongside the front-end so they stay in sync. We typically use Sanity, though we work with other platforms too.
We start building working prototypes early rather than spending weeks in Figma. You get something clickable in a browser within the first couple of weeks, which leads to better feedback and fewer late surprises.
It’s easy to build a slow Next.js site. Heavy client-side JavaScript, unnecessary re-renders, bloated bundles. We optimize from the start: minimal client JS, proper code splitting, image optimization, and caching strategies that keep Core Web Vitals green.
Why you should work with Bits&Letters
Principal-level expertise on every project
The person scoping your project is the person building it. Founded by David Demaree, with 25+ years including principal-level roles at Adobe (Typekit), Google (Material Design), Stripe, and Webflow.
Full stack, single partner
Front-end, CMS, hosting, design systems, API integrations. One team, one relationship, one Slack channel.
Built to last after launch
Most web projects fail after launch, not at launch. We design every project so your team can maintain and evolve the site once it's live. Clean architecture, thorough documentation, portable code. You're never locked in to us.
We'll tell you if you don't need Next.js
Most marketing sites don't. If Astro or a simpler approach would serve you better, we'll say so and explain why. We'd rather recommend the right tool than sell you on the most impressive-sounding one.
FAQs
When should I use Next.js instead of Astro?
When your site needs dynamic server-side functionality: personalization, authentication, complex data fetching, or heavy interactivity. For primarily static content sites, Astro delivers better performance with less overhead.
How much does a Next.js website cost?
$25K–$65K depending on complexity, interactivity requirements, CMS needs, and integrations. We scope every project after a discovery conversation.
How long does it take?
12–24 weeks from kickoff to launch. We have working prototypes in-browser within the first few weeks.
What CMS do you use with Next.js?
Usually Sanity. Its live preview works seamlessly with React-based frameworks like Next.js. We also work with Storyblok, Contentful, and other headless platforms.
Do you use the App Router or Pages Router?
We default to the App Router for new projects. It's the recommended approach from the Next.js team and offers better patterns for server components, layouts, and data fetching.
Where do you host Next.js sites?
Typically Vercel, which is built by the same team that builds Next.js. We also deploy to Cloudflare when the project requirements call for it.
Can you migrate an existing React app to Next.js?
Yes. We've migrated client-side React applications and sites from other frameworks to Next.js. The process depends on the existing codebase, but usually involves restructuring routing, moving data fetching server-side, and optimizing for performance.
What happens after launch?
30 days of post-launch support included. Ongoing retainers available starting at $5K/month. Everything is documented so your team can maintain the site independently.
