Can you recommend an easy-to-use SEO tool?

Guys, I'm in trouble here. I work in SEO myself and normally use Ahrefs and Semrush tools for checking and monitoring data. But my powerful laptop broke down, so I took it in for repairs. Right now I'm using my old one, and it's too weak to handle these services. They immediately start freezing as soon as I open them. But I still need to get work done. Are there any services with simpler tools available? Something that won't lag so much.

To be honest, I've long been disappointed with these heavyweight tools that every SEO specialist uses without exception. They consume significant computer resources and their subscriptions aren't cheap either. Yet I haven't found anything extraordinarily special about them. There are simpler alternatives that provide the same data without costing nearly as much. For example, try PR-CY https://pr-cy.io/ . Everything runs smoothly and doesn't freeze even on low-spec machines.
