Zephyr is the namespace for utility libraries in Synapse. Zephyr utilities are suitable for stand-alone usage outside Synapse.
Zephyr utilities are the stand-alone libraries we generate during Synapse development. Generally, we take them and wrap with Synapse Handlers, or link them in multiple Handlers as common libs. Either way, Zephyr libs are developed fully agnostic of Synapse consumption, and are therefore suitable for any number of integration use-cases. All Zephyr libs, along with other shared Synapse libs, are published on nuget.org.
