A chat application allows users to interact or communicate with each other by texting, messaging, video and audio conferencing. Adding a chat application can be useful for e-commerce websites which provide live support for their customers. Such chat applications help your business by getting real time feedback from your customer regarding products, service or content.

In this article I have gathered 10 Free Chat Applications for Your Websites which will help you communicate with your visitors and help you to enhance your business and sales. Following chat applications would easily integrate to your website and give your website an e-commerce website look and feel.

1. Scrollback



Scrollback is an open source web application for adding a modern chat for websites. It is built with Nodejs and can be either used with the free hosted version or by downloading and self-hosting it. The app creates a single room chat interface where the community can communicate with each other. An “infinite scroll” eases following the previous messages, all messages are presented with a timeline and it is possible to view user details.

8. Balloons.IO



Balloons.IO is a very impressive and open source chat application that is built with node.js, Express, Socket.IO and Redis. It has support for multiple rooms where users can join any of them, chat with other users and send files to each other. Also, there is an option for users to create their own rooms and set their statuses (available, away, busy). The application is simple-yet-solid and requires users to login with their Twitter accounts (which is good to keep the quality “up” but can be limiting). It also automatically fetches the avatar and uses with every message of each user.

9. Cryptocat



Cryptocat is an open source and web-based chat application that focuses on making sure that the communication is encrypted and private. It is built with PHP and works with a single file besides the static files (CSS, JS and images) used. For a private group communication inside a chat room with other users, a passkey (used by all of the group) comes to the rescue. The interface is simple-yet-nice and messages are encrypted with AES-256 using crypto.js library.

10. Hubot



Hubot is a chat bot, modeled after GitHub’s Campfire bot, hubot. He’s pretty cool. He’s extendable with community scripts and your own custom scripts, and can work on many different chat services. GitHub, Inc., wrote the first version of Hubot to automate our company chat room. Hubot knew how to deploy the site, automate a lot of tasks, and be a source of fun in the company. Eventually he grew to become a formidable force in GitHub.
