Since it is associated with the Flash platform, Silex is not well accepted by the open source fanatics.[18] It is mainly because Flash is not standard and therefore is not readable on some platforms, and it does not play well with assistive technologies.[19] The team said that the next version will also output HTML5, which would change all this.[20]

Silex has always had performances problems.[citation needed] This is because it is a mix of several technologies, including ActionScript 2 and javascript, which are known to be slow.[citation needed] And also it has a heavy framework inspired by traditional CMS.
