What is Vercel?
An overview of Vercel, the frontend cloud behind Next.js, and a map of this documentation.
Vercel is a cloud platform for building, deploying, and scaling web applications. The core promise: connect a Git repository, push code, and your site goes live on a global network — no servers to provision, no build pipelines to wire up by hand. Vercel detects your framework, builds it, and serves it close to your users automatically.
It's also the company behind Next.js, the most widely used React framework, and many Next.js features (ISR, Partial Prerendering, image optimization, middleware) are tuned to run natively on Vercel.
The mental model
The simplest way to picture Vercel is a pipeline triggered by Git:
git push -> Vercel builds -> immutable deployment -> Edge Network -> usersEach deployment is immutable: it gets a permanent URL and never changes once built. "Going to production" doesn't rebuild anything — it points a domain at an existing deployment, which is what makes instant rollbacks possible.
How this documentation is organized
- Getting started — How it works (the architecture) and the Getting started quickstart.
- Concepts — the building blocks: Deployments & environments, Functions & compute, Caching & ISR, and Builds.
- Guides — task-focused walkthroughs: Deployment workflow, Environment variables, Domains & DNS, and Cron jobs.
- Operations — running things in production: Observability and Security.
- Reference — Configuration (
vercel.json) and Pricing & plans. - CLI — the command-line interface, command by command.
