Mouseflow is a user experience tracking website. Developers and business can use to gauge what components of their site users are paying attention to or ignoring. Mouseflow offers four analytical features: mouse-tracking, click and move heatmaps, attention heatmaps that determine what parts of the page users scroll to, and what links generate more clicks. Their RESTful API allows developers to access reports and videos about their websites. The API returns XML and JSON-formatted data.
