Simperium vs Entity Signal: What are the differences?
Developers describe Simperium as "Move data everywhere it's needed, instantly and automatically". Simperium is a new kind of data layer. As your app reads and writes data, Simperium circulates that data everywhere it's needed. You add a Simperium library to your app and initialize it. This library keeps a persistent connection to the Simperium hosted service. The Simperium libraries and service work together to efficiently move data around for your users. On the other hand, Entity Signal is detailed as "A real time connection to entity framework core through Signalr Core". It allows you to connect to Entity Framework through SignalR and get updates on subscribed data in real time. This lowers the number of refreshes done by the user and ultimately allows you to do more with fewer servers.
Simperium and Entity Signal belong to "Realtime Backend / API" category of the tech stack.
