And we’ll scale right along with you

Want to start with text chat first, but add voice and video later? No problem! Or maybe start with a simple web app, but have ambitions to build mobile apps next quarter? Our cross-platform SDKs make it all possible.

Our team is obsessed with building the best in-app messaging tools available so you can confidently grow engagement in your own online community. That’s why we’ll never stop improving our core features, and thinking of clever new extensions you can’t get anywhere else. 

Two ways to implement.

Our react developers have literally spent thousands of hours building different in-app messaging solutions to meet your needs. 


React Chat UI Kits

If you’re looking for some customization and have a few hours to build a pixel-perfect design, try our React Chat UI Kit, which includes a fully polished UI and the complete business logic. We provide the source code, you can adapt it to fit your needs. 


React Chat SDK

A single line of code sets up a secure connection to our service using the same underlying protocol as WhatsApp.

Check out our React Chat Resource Center

We’re committed to your success, so we’ve set up a React Chat Resource Center, filled with easy-to-follow tutorials and inspiring ideas for how to take your chat to the next level, created just for React developers like you. 


{% c-block language="javascript" %}
var appID = "APP_ID";
var region = "REGION";
var authKey = “AUTH_KEY”
var appSetting = new
CometChat.init(appID, appSetting).then(() => {
 if(CometChat.setSource) {
      CometChat.setSource("ui-kit", "web", "reactjs");
console.log("Initialization completed successfully");
error => {
console.log("Initialization failed with error:", error);
// Check the reason for error and take appropriate action.
{% c-block-end %}


{% c-block language="javascript" %}
var uid = “UID”
CometChat.login(uid, authKey).then((user) => {
          if(user) {
console.log(“User login completed successfully");
           } else {
console.log(“User login failed");
        }).catch(error => {
console.log('CometChatLogin Failed', error);
{% c-block-end %}

Send a message

1) Send a message to a user

{% c-block language="javascript" %}
var receiverID = "UID";
var messageText = "Hello world!";
var receiverType = CometChat.RECEIVER_TYPE.USER;
var textMessage = new CometChat.TextMessage(
  message => {
    console.log("Message sent successfully:", message);
  error => {
    console.log("Message sending failed with error:", error);
{% c-block-end %}

2) Send a message in a group

{% c-block language="javascript" %}
var receiverID = "GUID";
var messageText = "Hello world!";
var receiverType = CometChat.RECEIVER_TYPE.GROUP;
var textMessage = new CometChat.TextMessage(
  message => {
    console.log("Message sent successfully:", message);
  error => {
    console.log("Message sending failed with error:", error);
{% c-block-end %}

Receive a message

{% c-block language="javascript" %}
var listenerID = "UNIQUE_LISTENER_ID";
  new CometChat.MessageListener({
    onTextMessageReceived: textMessage => {
      console.log("Text message received successfully", textMessage);
      // Handle text message
    onMediaMessageReceived: mediaMessage => {
      console.log("Media message received successfully", mediaMessage);
      // Handle media message
    onCustomMessageReceived: customMessage => {
      console.log("Custom message received successfully", customMessage);
      // Handle custom message
{% c-block-end %}

every kind of chat.
