Spark AR
Created by Facebook, Spark AR is an AR development software that is meant to make the development and deployment of AR apps as easy as possible. It comes with various templates and assets libraries and is capable of using many different forms of data as triggers (such as motions, sounds, facial expressions, etc.).
Effects are created using a visual coding language and can be customized further using javascript.
AR effects can only be published on Instagram or Facebook and both users and developers need accounts on said platforms.
