Vercel is a cloud infrastructure platform designed to simplify the deployment and hosting of modern web applications. It provides developers with a streamlined workflow for building, previewing, and scaling frontend-heavy applications, especially those built with frameworks such as Next.js.

The platform enables automatic deployments directly from Git repositories, generating preview URLs for every pull request and production-ready builds on merge. It abstracts away traditional infrastructure management by offering serverless functions, edge computing, CDN distribution, and built-in CI/CD pipelines.

Vercel is best known for being the creator and primary host platform for Next.js, which allows tight integration between framework features (like SSR, ISR, and API routes) and deployment infrastructure. It also supports other frontend frameworks and full-stack JavaScript applications.

In addition to hosting, Vercel provides a broader “frontend cloud” ecosystem that includes analytics, image optimization, edge middleware, AI tooling (such as v0), and serverless backend capabilities. It is widely used by startups and enterprises to deploy fast, globally distributed web applications with minimal configuration.

Key features include:

• Git-based deployments with automatic CI/CD
• Global CDN and edge network for fast content delivery
• Serverless and edge functions for backend logic
• Built-in support for Next.js and other frameworks
• Preview deployments for every pull request
• Analytics and performance monitoring tools

Common use cases include:

• Deploying Next.js applications
• Hosting SaaS products
• Building marketing websites
• Running serverless APIs
• Delivering globally distributed web applications

Vercel was founded in 2015 by Guillermo Rauch and originally known as ZEIT. It is the creator of Next.js and has evolved into a leading frontend cloud platform powering modern web development.
