Ember

Battle-tested JavaScript framework designed for ambitious web developers who want to be productive out of the box.

Overview

Ember.js is a battle-tested JavaScript framework designed for ambitious web developers who want to be productive out of the box. It includes everything needed to build rich, scalable UIs that work on any device—from routing and data management to testing and deployment—with a strong commitment to developer ergonomics and modern JavaScript practices.

The framework is built on the Glimmer rendering engine, one of the fastest rendering technologies available, and follows a predictable 6-week release cycle with straightforward upgrades. Ember's ecosystem includes hundreds of high-quality addons and tools like Ember Observer to help teams assess dependencies, making it ideal for organizations building long-lived, ambitious applications.
