VERDICT

Should I use Gtmetrix?

Find out why your website is slow. Then fix it. - gtmetrix.com

Worth it. Buy if you run a site and need detailed speed diagnostics — the free tier and $5.99 Lite plan cover most needs. Skip it if you just want a quick score (free PageSpeed Insights does that) or need real-user monitoring.
