I think this should be the only platform that could actually claim they are a true competitor of Semrush or Ahrefs. I got pretty much the same type of tools that i get from semrush like keyword research, backlinks and competition.

Database size is impressive, filters are extremely detailed, i'm really pleasantly surprised with this tool and that its on Appsumo

The limits are generous compared to other tools, and you give you literally thousands of data rows to work with, which is a huge plus. Definitely 5 tacos
