Felgo (previously V-Play Engine until February 2019[2]) is a cross-platform development tool, based on the Qt framework.
[3] Apps and games built with Felgo use a single code base and work across multiple platforms and screen resolutions.
[5] Felgo is based on the Qt (software) cross-platform development framework that provides abstraction layers for timers, threads, storage, networking and UI rendering on different platforms.
Felgo uses Qt as its core and offers components and plugins on top of it, which further simplify the development of apps and games.
It can inspect and change property values and QML code at runtime and is able to measure the time of element creation and binding evaluations.
