Questions tagged [krl]

KRL stands for Kinetic Rule Language. Use this tag for questions regarding KRL applications.

The Kinetic Rule Language was developed by Kynetx and runs on the Kinetic Event Architecture platform. KEA is a cloud-based platform for building real-time, context-aware applications that connect web services across multiple browsers and devices. It is the event layer that glues services like Twilio, Twitter, Google, Facebook, Amazon and others.

KRL is particularly useful for creating Evented systems. KRL is also used for writing Browser Applications. As such, KRL questions frequently overlap with questions about CSS, JavaScript, HTML, and jQuery.
