ably vs SignalR: What are the differences?

ably: A platform that makes it easy for you to add realtime messaging, notifications and streaming data to your applications. It enables any internet enabled device on the planet to publish data streams to any number of subscribers in milliseconds. Our infrastructure spans over 20 data centres globally ensuring low latency performance, redundant storage of all data and commitment to meet our guaranteed quality of service promise; SignalR: A new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.

ably and SignalR can be categorized as "Realtime Backend / API" tools.
