AppDynamics vs Insomnia

AppDynamics (application performance monitoring with business transaction tracking, owned by cisco, founded 2008) is typically a fit for Enterprise DevOps, Application Performance Teams, and IT Operations, while Insomnia (open-source rest, graphql, and grpc client for designing and testing apis, founded 2016) leans toward Developers, API Engineers, and QA Engineers. Both cover 3 of the same core capabilities, so the decision usually comes down to where they diverge.
