## What it is
AMP (AMPHTML) is an open-source web component framework for building fast, user-first websites, Web Stories, ads, and interactive emails using a library of ready-made HTML components. It enforces performance best practices such as asynchronous JavaScript and statically sized resources so pages load near-instantly.

## Use cases
- build fast mobile-friendly websites with web components
- create web stories for the open web
- build fast validated AMPHTML ads
- send interactive dynamic emails
- improve page speed and Core Web Vitals for publishers
- embed carousels, lightboxes, and forms without custom JavaScript
- integrate AMP into WordPress, Next.js, or Eleventy sites

## When to choose
- you run a content or publishing site where load speed and mobile page experience are critical
- you want copy-and-paste, performance-tested components without writing custom JS
- you need the Web Stories, AMP ads, or AMP email formats
- you want a component library usable standalone via Bento

## When to avoid
- you're building a highly interactive SPA or app-like product needing full custom JavaScript
- your team wants a modern mainstream framework with a large ecosystem
- you rely on Google AMP Cache benefits, which have been deprecated
- you need full design freedom without AMP validation constraints
