In our increasingly connected world, messaging platforms have become central to personal and professional communication. As the need for instant, dependable, and versatile communication options grows, developers are increasingly turning to chat APIs and SDKs to craft dynamic, feature-packed messaging experiences.
These tools are far from just add-ons — they are fundamental in crafting applications that engage and retain users through seamless interactions. Whether through text, voice, or video, having the right chat functionality can greatly enhance your chat platform's utility and popularity.
This guide will take you through the top chat SDKs and APIs of 2024, highlighting their unique features and how they can satisfy the diverse needs of developers and businesses like yours.
The popularity of messaging apps
Messaging apps have skyrocketed in popularity, reshaping how we talk, text, and even transact. In 2023, over 4.7 billion people globally used chat apps like SMS, WhatsApp, WeChat, and Facebook Messenger, with even more projected growth on the horizon. These platforms aren't just keeping us connected – they're offering quick, easy, and often cheaper alternatives to traditional methods of communication.
But it’s not just casual conversations driving the trend. Over half of consumers now prefer reaching out to businesses through chat apps, attracted by their immediate responses and straightforwardness. From video calls and handling payments to other tools, these apps are becoming multifunctional powerhouses.
Chat API vs chat SDK
Before we dig in further, let's clarify what chat APIs and SDKs are and why they matter.
A chat API (application programming interface) allows developers to integrate comprehensive messaging functionalities into their applications without the need to build the underlying backend infrastructure from scratch. This includes capabilities like sending and receiving messages, managing user interactions, and more, all accessible through a set of predefined commands that interact with a remote server.
An SDK (software development kit) is a toolkit for developers that includes libraries, tools, documentation, and code samples designed to aid in the application development process. When it comes to chat functionalities, an SDK will typically wrap around a Chat API for direct access, providing a more streamlined, higher-level set of tools that make it easier and quicker to implement chat features.
Why should you use a chat API?
When you're building an app that needs to let people chat, picking the right tools can make or break your project. A chat API is often a go-to choice for developers because it comes packed with features right out of the box.
It's like getting a Swiss Army knife for your app's messaging system – it has everything you might need.
1. Quick deployment
A chat API offers ready-to-use functionalities that drastically reduce the development time for integrating sophisticated features such as real-time messaging. This means developers bring their feature-rich applications to market quickly.
2. Enhanced scalability
A chat API takes over the intensive server-side processing, allowing developers to focus on expanding their applications. As user demand increases, the chat API facilitates a smooth scaling of services without a drop in performance.
3. High customizability
These tools are designed with flexibility in mind, offering a variety of customization options. This adaptability ensures that developers can create a tailored messaging experience that aligns perfectly with the specific needs of their applications and customers.
4. Security and compliance
Chat APIs often come with built-in security features, like end-to-end encryption, that help you meet GDPR compliance and other regulatory standards. This can significantly reduce the complexity and cost associated with securing communications.
5. Integration with other services
They easily integrate with other APIs and third-party services, such as CRM systems, payment gateways, or artificial intelligence services. This integration capability enables developers to create richer, more functional applications.
6. Cross-platform compatibility
They are designed to work seamlessly across various platforms and devices, ensuring a consistent user experience whether the user is on an Android or iOS mobile phone, tablet, or desktop computer.
Key features to look for
When choosing a chat API or SDK for your project, it’s important to assess your application's specific needs and select features that will create a powerful and enjoyable chat experience. If the tool lacks popular modern features that users expect, your app could deliver a poor user experience, which is exactly what you want to avoid.
Real-time messaging – Perfect for apps where timing is everything, like team collaboration tools or social media platforms. It keeps discussions brisk and responsive, with no message left behind.
Video chat – A key feature for any chat service focused on remote communication. It allows users to engage in face-to-face chats from anywhere, perfect for teams working from different locations or for keeping in touch with friends and family.
Group messaging – A group chat feature supports communication among multiple users in a single session. It helps create a sense of community and collaboration, especially in team-oriented apps or large-scale social platforms.

Push notifications – To keep users informed and engaged, push notifications alert them about new messages or updates within the app, even when they are not actively using it.
Message history and threaded conversations – Maintaining the chat history, or a log of previous conversations, is important to preserve context in ongoing discussions. This feature helps users catch up on unread messages and continue discussions without missing a beat.
Online presence indicators – This feature displays user presence by showing who's active and available, creating engagement by letting users know when their contacts are online and ready to chat.
Typing indicators – These indicators contribute to the dynamic and interactive nature of the chat experience. They inform users when someone is composing a message, providing real-time feedback that keeps the chat messages flowing smoothly and naturally.
Chat moderation tools – For platforms that require enforcement of community guidelines or content filtering, moderation tools are essential. They help maintain a safe and respectful communication environment.
Mentions – This feature allows users to directly notify specific individuals in a conversation by tagging them with the “@” symbol followed by the username.
Read receipts – Read receipts add a layer of transparency by indicating when messages have been viewed. This feature is especially important when information needs to be acknowledged and acted upon in a timely manner.
UI Kits – A UI kit provides pre-designed user interface components that can be easily integrated and customized within your app. These kits typically include various UI elements like buttons, input fields, and templates for chat bubbles, which help accelerate the design process and ensure a visually appealing and consistent user experience across different platforms.
