StackEye is a free Chrome add-on developed by RQ Labs that allows users to easily follow questions and users on StackOverflow and other StackExchange sites. With StackEye, users can receive notifications for new answers and comments on questions they are interested in.

The add-on features a simple and intuitive interface. Users can click on the eye icon to watch a question and receive notifications for any updates. They can also choose to unwatch a question if they are no longer interested. The extension's icon will show unread notifications, making it easy for users to stay updated on the latest activity.

In addition to following questions, StackEye v2.0 introduces a new feature that allows users to follow specific users on the StackExchange network. By going to the profile page of a user, users can simply hit the Follow button and start receiving updates on their questions and answers.

Some of the latest features of StackEye include the ability to import and export data, as well as the option to clear all notifications and followed questions and users with a single click.

Stay informed and keep learning with StackEye - the perfect tool for anyone looking to stay up-to-date with the latest activity on StackOverflow and other StackExchange sites.
