Inspectlet vs UserTesting: What are the differences?

Developers describe Inspectlet as "Record and playback everything visitors do on your site". Inspectlet records videos of your visitors as they use your site, allowing you to see everything they do. See every mouse movement, scroll, click, and keypress on your site. You never need to wonder how visitors are using your site again. On the other hand, UserTesting is detailed as "Get videos of real people speaking their thoughts as they use your website or mobile app". UserTesting provides on-demand usability testing. You create the test and we’ll get the testers. We let you “look over the shoulder” of your target audience while they use your website, so you can see and hear where users get stuck and why they leave.

Inspectlet and UserTesting belong to "User Feedback as a Service" category of the tech stack.

Some of the features offered by Inspectlet are:

• Identify individual users
• Capture interesting events
• AJAX, HTTPS, authentication, single-page apps: everything works straight out of the box

On the other hand, UserTesting provides the following key features:

• Video of the True User Experience
• Clips, Notes, & Sharing
• Detailed metrics
