When it comes to find the right framework for your company’s web application development, it can be quite difficult to know which one to choose. In this case, the first and the most popular names that come to your mind are the SignalR and the Socket IO.
While SignalR is more similar to SocketIO in terms of facilitating transport negotiation, there are key distinctions that make these two competitors.
This blog will cover all you need to know about SignalR and Socket.IO. Continue reading to learn more about their key differences.
Continue reading to learn more about their advantages and disadvantages, and key differences and similarities.
Though there are similarities that SignalR shares with Socket.IO, it appears as a framework rather than a server. As a result, the SignalR must be hosted on a server. The SignalR works with the host of ASP.NET, OWIN, and with the self-host. Hence you can consider using it with the windows service.
SignalR supports clients for the frameworks like .NET, Silverlight, Windows Phone 7, etc. Also, it helps to work with MonoTouch, iOS, etc.
When it comes to offering the API, you can use SignalR to get a much higher level of API compared to the raw sockets. It effectively allows you to do the things like the RPC from the server to the clients in a broadcast or a targeted style.
Unlike SignalR, Socket.IO does not work so smoothly with windows. It creates various issues regarding the installations. While SignalR is described as a new library for ASP.NET developers, which adds ease to real-time web development, Socket.IO, on the other hand, is a detailed real-time application framework.
The Socket.IO is extremely efficient in enabling real-time bidirectional communication, which is event-based. It is highly capable of working on most of the platforms, devices, and on the browser.
If you are looking for better speed and reliability while developing, then Socket.IO can be one of the best choices for you over SignalR. While SignalR is the top choice due to its reliability in working with the .Net server, Socket.IO lacks this functionality.
On the other hand, Socket.IO is a robust framework in terms of real-time development with ease.
To get a detailed overview, let’s discuss individual uses of SignalR And Socket.IO.
Socket.IO is best for:
SignalR is best for:
It offers multiple backplane options to select from when scaling out ASP.NET Core SignalR.
It is easy to use in combination with other ASP.NET features, including authorization, authentication, and dependency injection.
From creation to maintenance, SignalR transparently handles the connection for each client. Moreover, it supports the grouping of connections for broadcasting messaging to individual clients or client groups, as well as authentication and authorization for the connections.
It uses a high-level API named Hubs to allow server-to-client and client-to-server remote procedure calls. In addition to this, it also supports streaming methods, asynchronous methods, and model binding.
It offers weak messaging QoS where there is no guarantee of ordering and delivery. To ensure messaging is robust, developers will need to develop their own mechanism.
Scaling SignalR can be tough, expensive, and time-consuming.
The number of client SDKs is limited in SignalR. Also, there are no SDKs for languages such as Android, iOS, Go, PHP, or Ruby.
For running on the web server side, SignalR requires ASP.NET Core; similarly, for scaling out across multiple servers, it needs the Azure SignalR Service. This dependency on the ASP.NET Core framework and the Azure service can be a disadvantage as it might not be available or suitable for every scenario.
It doesn’t support horizontal scaling for streaming methods, which reduces the scalability and performance of streaming services that involve multiple clients or servers.
End-to-end encryption for messages is not supported by SignalR. Hence, messages can be read and modified by intermediaries, which reduces communication security and privacy.
Due to a simple API for both the client and server side, it is easy to use Socket.IO and implement real-time functionality into the application.
The use of namespaces helps minimize the TCP connections plus save socket ports on the server.
The use of broadcasting in Socket programming enables efficient data distribution in scenarios where there’s a need to spread the same message to multiple users.
Socket.IO allows easy integration with multiple solutions like Redis, MongoDB, Postgres, and AMQP / RabbitMQ for horizontal scaling.
The default messaging semantics don’t provide at-least-once messaging guarantee. Hence, there are chances that some messages are not delivered to recipients.
It doesn’t offer essential features such as push notifications, message history, webhooks, or serverless functions. Additionally, due to a lack of native support for end-to-end encryption and no Socket.IO mechanism, it’s tough to generate tokens for authentication.
Socket.IO is mainly designed to operate in a single region instead of multiple-region architectures. Hence, issues such as increased latency, system downtime, and more can be seen.

Besides multiple differences between SignalR and Socket.IO, there are many conceptual similarities between the two.
Here are the top similarities between SignalR and Socket.IO:
Based on the kind of requirements, you need to decide whether the Socket IO will be more efficient for you or the SignalR.
When it comes to building up the various web functionalities in real-time, it is hard for SignalR to beat Socket IO. However, SignalR also does have some promising functionalities which enable you to work in real-time.
On the other hand, in case of supporting with the. Net servers, it is tough for Socket IO to beat the SignalR.
With the comparison, we hope you are clear about which framework is right for you.
Both SignalR and Socket.IO are promising and have their own pros and cons. So, make sure to consider your needs and preferences for your web application building when choosing the framework.
After you’ve decided on the right framework for your web application, it's time for development.
