Plerdy is amazing. The UI/ UX is confusing and overwhelming in the beginning (can be improved). But after proper testing the software, this is really the best heatmap deal that has come to appsumo. (Yes, it's even better than the Crazyegg deal)

Heatmap
» Records on LIVE site instead of a screenshot which eliminates all the problems like misalignment and etc.
» Good filtering options. (you can even show data that comes from Ads!)
» Filtering options are more than most tools out there

Popup forms
» Basic but enough
» Design and templates are not as good as those from softwares that only do pop ups (sumo.com, convertbox, convertful)
» But you can get more data and analytics from Plerdy's popups.

SEO Checker
» Basic, but covers a wide scope
» Gives you a good overview of your SEO health
» Their SEO audit scans for technical SEO problems for every page.
» Word analysis scans for content problems for every page.
» GSC integration helps you find hidden keywords and potential content

Apart from heatmaps and SEO Checker, they also have session recordings, event/goal tracking, track sales back to button/ element, and conversion funnel tracking.
