Screaming Frog SEO Spider vs Sitebulb
If your site has fewer than 500 URLs, Screaming Frog's free version may be all you need: it crawls up to 500 URLs with no sign-up. For bigger sites, the paid licence is $279 a year (checked Oct 12, 2026), with no monthly option. Sitebulb has no free plan but can be paid monthly: Lite is $18 a month billed monthly (checked Oct 9, 2026) for audits of up to 10,000 URLs, with 100+ Hints that explain each issue. Site size and billing decide it: a small site can stay free on Screaming Frog, and a larger one that wants to pay monthly starts cheaper with Sitebulb.
