OpenSEO
See where you rank on Google and how you compare to competitors.
// WHAT IT'S FOR
OpenSEO is an open-source alternative to Semrush and Ahrefs. You research keywords, track your Google rankings, see which sites link to you and check how visible your competitors are. Instead of a subscription you pay per use through a DataForSEO account, or you try the hosted version on its site. It also connects to Claude or Codex.
