Top 8 Best Chat & Instant Messaging Protocols For 2022 (Reviews & Comparisons)

Building an instant messaging and chat application from scratch requires the development team to choose the right messaging protocol for its development. With several chat protocols in the market, it is essential to choose the right protocol that will develop a product to meet the demands of the target market. In this article, we are going to discuss the best chat protocols for business.

What Does User Datagram Protocol (UDP) & Transmission Control Protocol (TCP) Mean?

Transfer of data between devices is made possible by the networking communication protocols. UDP & TCP are two such network communication protocols that are used to build any kind of instant messaging protocol.

What is User Datagram Protocol (UDP)?

User Datagram Protocol is the first network communication protocol that is used to send data to a device without establishing a connection. It is most useful in the transmission of DNS lookups, video playback, and other time-sensitive data.

What is Transmission Control Protocol (TCP)?

Transmission Control Protocol is slower in transmitting data when compared to UDP. TCP establishes a connection through an automated process termed as ‘handshake’ which connects two devices – one which sends the data and the other which receives the data. It also checks errors and is the most commonly used protocol.

Best 8 Chat and Instant Messaging Protocols For Chat App

Out of the innumerable chat and instant messaging protocols that are available globally, we have hand-picked the best of them after thorough analysis. You can build chat applications using any of these.

List of Webchat Instant Messaging Protocols

1. WebRTC – Web Real-time Communication Protocols

WebRTC is an open-source framework that is built into the most commonly used browsers across the world. It is created by Google and uses APIs to establish a connection for real-time communication. It can bypass the firewall between two devices and does not require any third-party plugins or services. The greatest advantage of using WebRTC is having unmediated and direct access to the users.

Pros
  • End-to-end encryption
  • Open-source code
  • High-quality communication by the use of modern codecs
Cons
  • Companies that have large-scale projects cannot rely on WebRTC alone and require additional servers to share the load from browsers. This increases maintenance costs.

2.  WebSocket Instant Messaging Protocols

WebSocket provides low latency and real-time connection between server and client. It is the most commonly used communication protocol. WebSocket is used in the chat application, multiplayer online games, and social streams that update real-time. It is bidirectional and is supported over most of the browsers that are used today.

Pros
  • Cross-origin communication is possible
  • It provides a continuous connection
  • It can pass through firewalls
Cons
  • Browsers launched a few years back do not support WebSocket

3. Internet Relay Chat (IRC) Chat Messaging Protocols

IRC is one of the oldest instant messaging protocols that provide a connection for more than two users to chat with each other at the same time. When you build a chat app for Android, you can utilize IRC that transmits real-time messages. It was introduced even before the creation of the World Wide Web (WWW). IRC can run on either UDP or TCP ports.

Pros
  • Multiple user’s chats can be transmitted
  • End-to-end encryption
  • Proxy detection
Cons
  • IRC protocol can be run only on IRC network and server

List of Cross-platform Chat Protocols

4. XMPP : Extensible Messaging and Present Messaging Protocol

Data of Extensible Markup Language (XML) is transmitted over XMPP. Two or more devices that are securely connected using their servers can use XMPP for data transmission. XMPP messaging protocol for chat apps has several free clients and open-source clients which make it easy to transfer data. Businesses can stream voice calls, video calls, 1-to-1, and multi-party chats using XMPP.

Pros
  • Data transmission is possible between servers of different architecture
  • Cross-platform data transmission is possible
  • Continuous connection
Cons
  • Text-based communication can cause server overload

5. Message Queuing Telemetry Transport (MQTT)

MQTT allows machine-to-machine telemetry and is a lightweight messaging protocol that is popular in IoT connections. It enables communications and automation of IoT devices. This is mostly used for smart homes. It is the best web chat protocol as it helps in the transmission of data between all modern devices.

Pros
  • Enables bi-directional communication
  • Can be used even for small bandwidth environments
  • The continuous connection provides support for unreliable network
Cons
  • Does not help in video streaming

6. Session Initiation Protocol (SIP)/SIMPLE

The instant messaging protocol that is built on SIP is termed as Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE). SIMPLE is a text-based protocol that is most commonly used in instant messaging, private telephone systems, and mobile calls over the LTE network.

Pros
  • Easy debugging
  • Open-source code
Cons
  • Does not have built-in encryption

7. Advanced Message Queuing Protocol (AMQP)

AMQP can be utilized in the multi-client environment as it uses a streamed binary messaging system. This enables the operation of clients from multiple vendors. This can be used to build WebSocket chat applications as it is portable, secure, and efficient.

Pros
  • Secure connection
  • Allows interoperability
Cons
  • High bandwidth is required

List of Android Chat Protocol

8. Rich Communication Services (RCS)

RCS can transmit audio, video, group chat, read receipts, images, etc. Businesses can create interactive text messaging experiences for their users using RCS while building chat apps for Android. It is the best technology for chat applications which enables the users to make purchases and sales within the chat app.

Pros
  • Reduced phishing and spam attempts
  • Easy transmission of rich media
Cons
  • No end-to-end encryption

Conclusion

As a business, when you have to choose a chat protocol for your chat app this is what you need to consider – what are the use cases of your instant messaging app, your resources in hand, and the protocol’s compatibility with your tech stack. Once you answer these three questions, you will be able to pick the one that will suit your business the best.
