What is Next.js?

Next.js is an open-source React framework from Vercel for full-stack web applications. Server rendering, static generation and APIs work in one project, so pages load fast and get indexed well. Synapse Team builds SaaS, client portals and internal services on Next.js, and the Payload admin of the agency’s own site runs on it.

When we choose Next.js

Next.js is strongest when a project works like an application: accounts, personal data, information that changes every minute. The interface and the server logic sit in one project, so development is faster and support is simpler.

  • SaaS, dashboards and client portals with complex logic
  • Dynamic pages that must be in Google: server rendering is built in
  • The best match for Payload: the CMS installs right into Next.js
  • One TypeScript project for the interface, API and background tasks

When we recommend something else

Not every project needs Next.js. Here is when we honestly recommend another option, and build it ourselves.

  • A marketing site or blog: Astro loads faster
  • Your team is used to the WordPress admin: classic WordPress
  • A storefront without complex logic: lighter on Astro
  • A simple landing page: a static site without a framework

Technologies we build with

AI-fast or classic: you choose the pace

AI speeds up development, engineers guarantee quality: a senior engineer reviews every page, API and test before release. Prefer a traditional process? We run that too, with the same quality bar.

Frequently asked questions

Next.js or Astro: which one for my project?

A simple split: if most pages are content, Astro is lighter and loads faster. If the project works like an application with accounts and live data, you need Next.js. Our own site uses both: the website on Astro, the Payload admin on Next.js.

How much does Next.js development cost?

The framework does not change our pricing:

  • SaaS MVP on Next.js: AI from $4,000 (4–6 weeks), classic from $10,000 (10–12 weeks).
  • Internal tool on Next.js: AI from $4,000 (3–6 weeks), classic from $6,500 (6–10 weeks).

Who develops Next.js?

Next.js is open source and is developed by Vercel, the company behind the cloud platform of the same name. Products by Netflix, TikTok and Nike run on it, and its ecosystem is among the largest in web development.

Is Next.js still relevant in 2026?

Yes. Next.js remains the most popular React framework by npm downloads, major releases ship every year, and modern tools are built on it: Payload CMS, for example, installs right into a Next.js app.

Is Next.js frontend or backend?

Both. Next.js shows the interface and runs server code in one project. Most products need no separate backend, which means shorter timelines and simpler hosting.
