Vercel makes deployment feel like magic — you push code and seconds later it's live worldwide. But what's actually happening under the hood?

What is Vercel?

Vercel is a cloud platform built specifically for frontend frameworks like Next.js, React, and Svelte. It handles everything from building your code to serving it to users across the globe — with zero server configuration needed.

Step 1 — You Push Code to GitHub

Everything starts when you run:

bash

git push origin main

Vercel watches your GitHub repository via a webhook. The moment a push lands on your connected branch, Vercel is instantly notified and kicks off a new deployment.

Step 2 — Vercel Pulls Your Code

Vercel clones your repository into an isolated build environment. This is a clean, sandboxed container — completely fresh every single time.

Step 3 — The Build Runs

Vercel runs your build command. During this step TypeScript is compiled, pages are pre-rendered, and assets are optimised.

Summary

Vercel's deployment flow is: push → detect → build → distribute → live. What used to take hours of server configuration now happens automatically in seconds.
