Accelerated Mobile Pages format and tooling for fast, cacheable mobile web content.

Overview

AMP (Accelerated Mobile Pages) is an open-source web component framework designed to create fast, user-first experiences across multiple formats. It provides a structured approach to building websites, interactive stories, dynamic emails, and high-performance ads by enforcing performance best practices at the framework level.

The framework works by applying seven core optimizations: asynchronous JavaScript execution, static resource sizing, non-blocking extensions, third-party script sandboxing, inline CSS with size limits, efficient font loading, and GPU-accelerated animations. These constraints ensure pages load instantly and remain responsive even on slower connections.

AMP supports multiple use cases including publisher websites, e-commerce platforms, advertising networks, and email senders. It's maintained by the OpenJS Foundation and has been adopted by major organizations like the Washington Post, Booking.com, and numerous publishers and advertisers worldwide.
