Adding chat to your website is a must nowadays. Whether you need chat for community engagement, live streaming, virtual events, in-app chat, gaming chat or customer centric chat

Chat has become an important part of our lives and one that we cannot really live without. 

Building out chat functionality for our needs is a difficult endeavor and here comes the chat API and SDK providers.

You can easily add chat that scales with these providers and have a chat for any use case that you might have

## What is Chat SDK?

SDK or Software development kit is a group of functions or methods that are provided to you by the chat SDK provider

Methods are easy to use functions that does something like adding a user to the chat or sending a message. They basically hide the complex functionality that is required to achieve a task such as adding a user to chat and gives you an  easy to use function that you can call to achieve your task.

Along with Methods SDKs often comes with events. Events are a trigger to something that is happening in the chat.

For example: When a message is sent in the chat room an event is triggered, you can listen on to this event through function given in the SDK and perform certain action if you wish to.

## Difference between Chat SDK and API

API stands for Application Programming Interface enable a chat provider to open up its functionality to third party applications.

Chat APIs might include APIs to export the messages from a chat room or API that lets you know how many users are there in a chat room

SDK is a set of tools that is provided by the chat provider, it might include APIs or methods that call the API to fulfill a purpose.

SDK might include methods that call the APIs for a specific purpose like SDK method might call the API to add and user and then call the API to send a welcome message once the user has entered the chat room

## Features and Pricing to evaluate the Chat SDK

To get a pre-built chat solution, you must consider what features you might require in the solution.

Some of the features could be the following:
1. Ability to handle massive amounts of concurrent users
2. Ease of adding the Chat to your website or app
3. customization
4. Group Chat
5. 1-1 Chat
6. Chat Moderation
7. SSO

Beware though not all chat solutions offer these features. We have created a list of chat providers and what features they offer so that you can make the decision for your self.
