Netlify pioneered the git-connected frontend workflow: push a branch, get a deploy preview; merge, and the site ships to a global CDN with serverless functions, forms and redirects handled by configuration. It stays deliberately framework-agnostic across React, Vue, Svelte, Astro and plain static sites.
It suits web teams shipping marketing sites, docs and frontend apps who want deployment automated away. The comparison is Vercel: Netlify is the neutral platform, Vercel the one with Next.js gravity.
