📌 What Is Next.js?

Before diving into who built it, it's important to understand what
Next.js is:

Next.js is a React framework that enables:

• file-based routing\
• server-side rendering (SSR)\
• static site generation (SSG)\
• API routes\
• image optimization\
• edge rendering\
• hybrid rendering models\
• full-stack development capabilities

It simplifies React development by handling performance, routing,
bundling, server rendering, and deployment seamlessly.

But how did this powerful framework come to life? Let's explore.

🧑‍💻 The Creator of Next.js --- Guillermo Rauch

The primary creator and visionary behind Next.js is Guillermo Rauch,
an Argentinian software engineer, entrepreneur, and the CEO of
Vercel.

Guillermo is known for his deep influence on the modern JavaScript and
Node.js ecosystem. Before building Next.js, he contributed significantly
to technologies such as:

• Socket.io (real-time communication)
• Mongoose (MongoDB ODM)
• NPM popular libraries in the Node.js ecosystem
• Micro (a minimalist server framework)

His long-standing philosophy has always emphasized:

• performance\
• simplicity\
• developer experience\
• scalability

These principles became the foundation of Next.js.

When he founded Vercel (then called Zeit) in 2015, he envisioned tools
that would make the web faster, more accessible, and easier to
build.

Next.js emerged directly from this mission.

🚀 The Birth of Next.js (2016)

Next.js was officially released in October 2016 by Vercel (Zeit at
the time).

The motivation behind creating it was clear:

React was powerful, but missing:

• routing\
• SSR capability\
• configuration-free setup\
• performance optimizations\
• deployment simplification

Developers were struggling to create production-ready React applications
because they had to configure Webpack, Babel, routing, hydration, SSR,
image optimization, and more manually.

Next.js was built to solve all of these problems.

The earliest version of Next.js offered:

• file‑system routing\
• zero‑config setup\
• built-in SSR\
• hot reloading\
• server-side bundling

This immediately caught the attention of the React community.

🏢 The Company Behind Next.js --- Vercel

While Guillermo Rauch is the creator, Next.js is developed and
maintained by Vercel, a cloud platform that specializes in edge
deployment and serverless architecture.

What Is Vercel?

Vercel is a platform built for:

• hosting front-end applications\
• deploying serverless functions\
• supporting edge rendering\
• simplifying CI/CD

It is designed to pair perfectly with Next.js, although it supports
other frameworks as well.

Why Vercel Built Next.js

Vercel's mission is to create a faster, more performant web. To achieve
that mission, they needed a framework that aligned with:

• instant deployment\
• performance-by-default\
• global edge networks\
• hybrid rendering

Next.js became the perfect companion to Vercel's infrastructure
ecosystem.

🧱 The Engineering Team Behind Next.js

Although Guillermo is the creator, Next.js has grown into a massive
engineering project with contributions from hundreds of developers.

Some of the notable engineers who contributed significantly include:

▲ Tim Neutkens

One of the earliest contributors and the current lead maintainer of
Next.js.

▲ Lee Robinson

VP of Developer Experience at Vercel, instrumental in documentation,
demos, education, and community growth.

▲ Shu Ding

Known for building advanced features such as streaming, rendering
optimizations, and edge technologies.

▲ Steven Levine

Key contributor to bundling, performance, and server architecture.

▲ Tanner Linsley

While not a core Next.js engineer, he built React Query and joined
Vercel, influencing the data-fetching ecosystem of Next.js.

▲ Dan Abramov & the React Team

Although not direct Next.js developers, the React Core Team heavily
collaborates with Vercel for:

• React Server Components\
• Concurrent features\
• Streaming architecture\
• Suspense integrations

The synergy between Meta's React team and Vercel's engineering team has
advanced the web ecosystem significantly.
