Groove Funnels is a marketing platform that helps you to create sales funnels, landing pages, email marketing, CRM, partner management hub, and more.
Kartra, on the other hand, is a highly effective digital marketing tool. It uses an out-of-date page maker and does not follow a mobile-first approach.
Since it uses new and 10x improved frameworks, Groove Funnels is more strong. It will also come with an SDK, enabling someone to build applications for it.
