NATS vs Entity Signal: What are the differences?
Developers describe NATS as "Lightweight publish-subscribe & distributed queueing messaging system". Unlike traditional enterprise messaging systems, NATS has an always-on dial tone that does whatever it takes to remain available. This forms a great base for building modern, reliable, and scalable cloud and distributed systems. 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.
NATS and Entity Signal can be primarily classified as "Realtime Backend / API" tools.
