Better Tools, Better Experiences

Dojo Performs Better

Explore TaskSpeed to see how Dojo's easy to learn API provides the perfect balance between speed and ease of use. Dojo is 1.5-2x faster than jQuery, and the difference is biggest on the slowest browsers — where it counts most.

TaskSpeed run times in ms, smaller is better.

Dojo Saves You Time

Incredible performance shouldn't mean complex, hard-to-use APIs so dojo.query() simplifies every-day web development tasks without sacrificing performance. From JavaScript utilities to DOM and CSS helpers to event handling and CSS selectors, Dojo gives you simple and fast utilities no designer or developer should be without. At the same time Dojo opens up a world of possibilities thanks to its innovate package system.

Incredible Depth

Dojo's package system gives you easy access to a rich set of UI components, a powerful data abstraction, and a wealth of extensions that build on each other to help you build ever-more sophisticated applications. We've even got accessibility and internationalization covered. No need to fend for yourself or start over when you think you've hit a wall; Dojo's maturity and backward-compatibility ensure you'll have the tools you need when you need them.
