Rank Math is an excellent SEO choice for WordPress, with a generous free version; outside WordPress it doesn't apply.
About
In practice. What you can do with Rankmath.
RankMath is Yoast's main competitor on WordPress, with a similar approach (on-page optimization, sitemap, technical tags) but a more generous free version: multi-keyword tracking and Google Search Console integration included for free, where Yoast reserves them for the paid plan.
The choice between the two is mostly a matter of habit and interface; RankMath is often recommended for those who want more features without paying.
Practical uses
