5 Best Real-Time Chat APIs and Messaging SDKs in 2024 (Plus One Game-Changer)

In today's digital landscape, real-time chat APIs and messaging SDKs play a crucial role in enhancing customer engagement and communication for businesses. With a plethora of options available, selecting the perfect solution can be a challenging task. This article aims to guide you through the process of choosing the best real-time chat API or messaging SDK, analyzing the top 5 options, and introducing Tencent Chat as an excellent alternative.

What Are Chat APIs and SDKs?

Chat APIs and SDKs enable developers to build web and mobile applications with real-time messaging capabilities quickly and efficiently. They manage the underlying infrastructure required to send and receive messages, along with additional features like typing indicators, online status indicators, and read receipts. A chat API provides direct access to the infrastructure, while a chat SDK offers prebuilt UI components and tools for streamlined development.

What Should You Look for in a Live Chat Solution? 

1.Low Latency: Ensure a smooth user experience by minimizing message send and load times.

2.Scalability: The solution should handle increasing user volumes and server loads without compromising performance.

3.Reliability: The solution should provide uninterrupted service and minimize downtime or errors.

4.Guaranteed Delivery: Messages should be delivered exactly once and in the correct order, even in the face of network issues.

5.Elasticity: The solution should dynamically scale resources to accommodate sudden spikes in usage.

6.Rich Features: Offer essential features like typing indicators, online status indicators, read receipts, and push notifications.

7.Integrations: Seamlessly integrate with your existing tech stack to minimize engineering requirements.

8.Data Governance: Ensure compliance with regulatory requirements for data storage, processing, and disposal.

9.Chat Moderation: Maintain a safe and compliant chat environment for both users and operators.

10.Frontend UI: Provide customizable UI components to ensure a cohesive customer experience.

The 5 Best Real-Time Chat APIs and Messaging SDKs

Ably: Best for Reliable Real-Time Experiences Ably is a real-time experience infrastructure provider that offers a comprehensive suite of APIs for building feature-rich and reliable chat applications. Its new chat product, Ably Chat, provides low latency, guaranteed message ordering, and a 99.999% average uptime SLA.

Twilio: Best for Omni-Channel Communication Features Twilio's Conversations API is designed to enable seamless omni-channel messaging experiences across various platforms, including WhatsApp and in-app chats. However, its chat feature set is limited compared to other solutions.

Firebase: Best for Existing Firebase Users Firebase is a comprehensive app development platform that offers real-time database capabilities for storing and broadcasting chat messages. While it may require significant upfront development for advanced chat features, it is an attractive option for existing Firebase users.

Sendbird: Best for a Quick, Out-of-the-Box Chat SDK Sendbird provides a chat SDK with ready-made UI components, enabling developers to quickly integrate chat functionality into their applications. However, its pricing can become opaque at higher scales, and it may have latency issues due to its single data center approach.

Stream (formerly GetStream): Best for a Chat API + UI Kit Offering Stream offers chat APIs and UI components that enable developers to build rich chat experiences with features like typing indicators, user presence, and threaded conversations. However, its single data center can impact latency and reliability.

Get Started With Tencent Chat

Tencent RTC stands as a robust platform for real-time communication. The service supports high-quality audio and video interactions. Developers can integrate Tencent RTC into web, iOS, Android, and other major development frameworks. Our platform ensures seamless connectivity for users worldwide.

Step 1: Create a project

Create a new React project. You can choose whether to use a TS template or not.

npx create-react-app sample-chat --template typescript

After the project is created, go to the project directory.

cd sample-chat

Step 2: Download the chat-uikit-react component

Use npm to download chat-uikit-react and use it in your project. Additionally, related open source code is also provided on GitHub, which you can use as a basis to develop your own component library.

npm install @tencentcloud/chat-uikit-react

Step 3: Include the chat-uikit-react component

Note:

• In the following code, SDKAppID, userID, and userSig are not input. Acquire the necessary information in Step 4 and replace it accordingly.
• npm Integration Method
• Source Code Integration Method
• Replace the content in App.tsx, or you can create a new component for inclusion.

import React, { useEffect, useState } from 'react';
import { ChatSDK } from '@tencentcloud/chat';
import { TUIKit } from '@tencentcloud/chat-uikit-react';
import { TUILogin } from '@tencentcloud/tui-core';
import '@tencentcloud/chat-uikit-react/dist/cjs/index.css';


export default function SampleChat() {
  const [chat, setChat] = useState<ChatSDK>();
  const init = () => {
    const loginInfo = {
      SDKAppID: 0, // Your SDKAppID. Get it from Step 4
      userID: 'xxx', // Your userID. Get it from Step 5
      // UserSig is a cipher for a user to log in to IM. It is the ciphertext generated by 
      //encrypting information such as userID. Get it from Step 5
      userSig: 'xxx', // Your userSig. Get it from Step 5
      useUploadPlugin: true,
    };
    TUILogin.login(loginInfo).then(() => {
      const { chat } = TUILogin.getContext();
      setChat(chat);
    }).catch(() => {});
  }
  useEffect(() => {
    init();
  }, [])

  return (
    <TUIKit chat={chat} language={'en'}></TUIKit>   // language support en or zh
  )
}

Step 4: Create an application

1. Log in to the Chat console.

2. Click Create Application, enter your application name, and then click Create.

3. After creation is complete, you can view the status, service version, SDKAppID, creation time, tag, and expiration time of the new application on the console overview page.

Step 5: Obtain userID and userSig

Click the target application tab, enter the Account Management page, create an account, and obtain userID.

Go to the IM console > UserSig Tools , enter the userID to generate a userSig, and copy the userSig. For more information about userSig, see Generating UserSig.

Step 6: Start the project

Replace SDKAppID, userID, and userSig in App.tsx, and then run the following command:

 npm run start

Note:

1. Ensure that SDKAppID, userID, and userSig are successfully replaced in Step 3, as the failure to do so may cause the project to operate abnormally.
2. A userID corresponds to a userSig. For more information, see Generating UserSig.
3. If the project fails to start, please check whether the environment requirements are met.

Step 7: Send your first message

1. After starting the project, click + on the left to start a one-to-one chat.

2. Enter the userID created in Step 5 in the search box, and then press Enter.

3. Enter your message in the input box and press Enter to send.
