SignalR vs ably: What are the differences?
- Performance and Scalability: SignalR is designed to provide real-time communication between a client and server using various transport protocols, such as WebSockets and Long Polling. However, ably offers a more scalable solution by providing a global network of data centers, enabling high performance and low latency communication across the globe.
- Reliability and Fault Tolerance: SignalR relies on the stability and availability of the underlying infrastructure, which can lead to potential issues in case of server failures. In contrast, ably ensures high reliability and fault tolerance by automatically handling server failures and seamlessly switching to available backup servers.
- Cross-Platform Support: While SignalR primarily focuses on .NET platforms, ably offers cross-platform support for various programming languages including JavaScript, Java, Python, and more. This flexibility allows developers to use ably in their preferred programming language and integrate it with different client technologies.
- Real-Time Features and Push Notifications: SignalR provides real-time communication capabilities, but it lacks built-in push notification functionalities. ably, on the other hand, offers a comprehensive set of real-time features along with push notifications, allowing developers to easily send notifications to clients on various devices.
- Presence Functionality: SignalR does not provide native support for presence functionality, which allows tracking the online status or availability of users. However, ably offers built-in presence functionality that enables developers to monitor the presence of users and receive notifications when users join or leave a channel.
- Operational Insights and Monitoring: ably provides real-time operational insights and monitoring features, including dashboards and analytics, which allow developers to gain visibility into the health and performance of their real-time applications. SignalR does not have built-in monitoring capabilities, requiring developers to implement their own monitoring solutions.
In summary, ably offers enhanced performance, scalability, reliability, cross-platform support, real-time features, presence functionality, and operational insights when compared to SignalR, making it a robust choice for real-time communication and push notification requirements.

What is Ably?
Ably offers WebSockets, stream resume, history, presence, and managed third-party integrations to make it simple to build, extend, and deliver digital realtime experiences at scale.
What is SignalR?
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.
