Top 08 Best Chat & Instant Messaging Protocols For 2023 (Reviews & Comparisons)
Building an instant messaging and video conferencing application from scratch requires the development team to choose the right messaging and signaling protocol for its development.
With several Android, iOS and web 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 real-time chat
WebSocket provides low latency and real-time communication sessions between server and client. It is the most commonly used communication protocol.

What Does User Datagram Protocol (UDP) & Transmission Control Protocol (TCP) Mean?/ What are the common messaging protocols?
Transfer of data between devices is made possible by the computer network 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 the 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 or im protocols that are available globally, we have hand-picked the best of them after thorough analysis. And, you can build web chat applications using any of the below protocols.
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 signaling server is having unmediated and direct access to the users.
2. WebSocket Instant Messaging Protocols
WebSocket provides low latency and real-time communication sessions between server and client. It is the most commonly used instant message protocol. They can be 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.
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.
List of Cross-platform Chat Protocols
4. XMPP : Extensible M XMPP messaging protocol for chat apps 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 application has several free clients and open-source clients which make it easy to transfer data. Further, this protocol helps businesses can stream voice calls, video calls, 1-to-1, and multi-party chats using XMPP.
5. Message Queuing Telemetry Transport (MQTT)
The next one under the list of messaging protocols is MQTT . It 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 with WebRTC peer to peer. 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.
6. Session Initiation Protocol (SIP)/SIMPLE
The instant messaging protocol or im 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 chat system, private telephone systems, and mobile calls over the LTE network.
7. Advanced Message Queuing Protocol (AMQP)
Moving over to the next best protocol for chat application is Advanced Message Queuing Protocol.
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.
List of Android Real-Time 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.
As a business, when you have to choose the best protocol for a chat application, 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.

Frequently Asked Questions (FAQs
Does instant messaging use TCP or UDP?
Depending on the application, Instant messaging uses both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), as per needs.
TCP is a connection-based protocol that transmits data packets in an order. An IM system initiates and authenticates a chat connection using TCP. The instant message protocol is commonly preferred for file transfers and emails where orderly transmission of data packets must take place to avoid errors.
UDP, is a connectionless protocol that does not follow any order in the transmission of messages. This protocol is commonly used for low-latency real-time chat , voice and video call.
What are two popular chat protocols?
The two most popular chat protocols are:
XMPP (Extensible Messaging and Presence Protocol): XMPP is an instant messaging protocol that supports features like file transfers, online presence indicators and group chats.
IRC (Internet Relay Chat): IRC is a text-based real time messaging protocol that supports features like one-to-one messages, file transfers, chat rooms and channels
What are the types of TCP protocol?
There are different types of TCP data packets that facilitate instant chat communication across devices and a few of them include:
SYN – synchronize
URG – urgent
FIN – finish
PSH – push
ACK – acknowledge
Which protocol is used in MirrorFly chat API?
WebRTC, WebSockets, XMPP, IRC, MQTT, SIP, and AMQP are some of the real-time messaging protocols used in MirrorFly Chat SDK.
