Current limitations

Horizon is rapidly evolving

Currently, Horizon is well-suited for a simple to moderately complex front-end application. It’s possible to build a new Node app with Horizon, but it may be something of an adventure. Porting an existing Node application to Horizon may be difficult or even impossible. All of this will change in the future!


Horizon should be compatible with most popular browsers, although it hasn’t been extensively tested with older versions. If you expect to run Horizon on browsers that do not support JavaScript ES6 promises, you will need to supply a polyfill to support them, such as es6-promise.

Currently, Horizon has issues with Mobile Safari. This will be addressed in an upcoming release.

There may be issues with Internet Explorer (see issue #566).

The Horizon server requires Node.js version 4.4 or higher, and the corresponding version of npm.

Setting up a Horizon server under Windows has not been extensively tested.
