Verdict:Leave SpyFu when you need a wider SEO suite, or when your research is mostly about your own site rather than rivals. Semrush is the broad paid choice, with a small free account of one demo project and 10 reports a day, and paid starting at $139 a month billed monthly. Ahrefs is known for its backlink index, and its free tier covers unlimited verified sites with Site Explorer capped at 1K backlinks; its Starter plan is $29 a month. SE Ranking bundles rank tracking with research, with Core at $129 a month billed monthly or $103.20 a month on annual billing. Seobility is the low-cost checker: its free Basic plan allows five checks a day and Premium is $69.90 a month. Screaming Frog is a desktop crawler, free up to 500 URLs, with a paid licence at $279 a year for unlimited crawls. Screaming Frog is technical only and has no competitor keyword database. Choose Semrush or Ahrefs if you need rival keyword and link data in one place, SE Ranking if client reporting matters, and Screaming Frog if you only audit your own pages. The trade-off is that none of the cheaper tools reproduce the competitor keyword history that makes SpyFu useful, so expect to combine two tools. Export one month of your current research before you cancel.
