SEO Utils

Desktop SEO software usually bills monthly, but SEO Utils is sold as a one-time license with lifetime access to the current version.

SEO Utils is an SEO tool for macOS, Windows and Linux that covers keyword research, keyword clustering, backlink analysis and rank tracking in one app.

Clustering has no subscription fee and no cap.

SEO Utils connects to Google Search Console without keyword limits, so you can pull your own query data in full.

Backlink and traffic data come through DataForSEO, so you need a DataForSEO account for those parts.

Some features may call for an OpenAI API key, though local models are supported if you would rather skip it.

The catch is updates.

Free updates last one year after purchase, and after that you keep the version you own.

That works for people who want a fixed cost and can live without new releases.

It is not the same as a subscription that keeps improving.
