Minnit allows you to create a free HTML5 chatroom for your website. It's supported on almost all devices and users aren't required to download an app or register to join your chat. It's a great way to boost user engagement on your website by talking with your visitors.

You can change the chat's appearance and color, turn captcha on/off, change who can send links, how long your staff can ban for, customize your smilies and much more, all for free.
