Out of curiosity I decided to give VStats a try and I am pretty impressed with what I am seeing. I have been on the lookout for such a tool but did not want the freemium model. As a beginner I really like what I see here - I feel it is extensive, easy to understand and also links to the big names in the business - all just from the extension.

Here is a screenshot of what it showed me of the Appsumo homepage - https://markuphero.com/share/J098OM1DXnKGpkjeQJ1W

As you can see, from within the extension it not only gives you an overview but then goes into details about sources, links and keywords too.

One challenge that I am facing is - even though I am registered it keeps asking me to log in. When I click login, it takes me to a new page that shows I am registered for the login version. Could you please look into this?

Overall, I am very pleased with this and hope it grows leaps and bounds. All the best :)
