1. A plugin certification system for certifying compliance of plugins at build time, the plugin certification system comprising: a processor; a first non-transitory computer-readable memory in communication with the processor, the first non-transitory computer-readable memory storing compiler instructions that when executed by the processor direct the processor to compile source code for implementation of a web application; and a second non-transitory computer-readable memory in communication with the processor, the second computer-readable memory storing plugin certification instructions that when executed by the processor direct the processor to: receive source code defining a plugin for the web application; determine a plurality of platform plugin standards for certifying plugins; initiate a plugin build process for the source code; during the plugin build process, compare the received source code to the plurality of platform plugin standards; determine, based on the comparing, that the source code meets all of the plurality of platform plugin standards; and after determining that the source code meets all of the plurality of platform plugin standards, compile the source code, in accordance with the compiler instructions, for implementation of the web application via a client delivery system.
