Serve is a lightweight command-line tool that makes it effortless to host static files, single-page applications, and websites locally or across your network. Built by Vercel, it handles all the technical details you'd normally need to configure manually.

Key capabilities include:

HTTPS support for secure local development
CORS headers for cross-origin requests
GZIP compression to reduce file sizes automatically
Directory listing UI with an intuitive interface for browsing folders
Zero configuration - just run npx serve and you're ready
Flexible deployment - serve any folder or specific files
Middleware integration - use the core serve-handler in your own HTTP servers

Getting started takes seconds. Run npx serve in your project directory, and your files are instantly accessible. For permanent installation, use npm install --global serve. Customize behavior with a simple serve.json configuration file when needed. The tool requires Node v14 or higher and maintains a minimal footprint, making it ideal for development workflows, testing, and quick file sharing without complex setup.
