Our verdict
It depends on your prioritiesTwo desktop crawlers with the same job and opposite billing.
TechBigs verdict, published Sep 4, 2026
Screaming Frog is cheaper over a year and has no per-audit URL ceiling. Sitebulb is easier to hand to someone who is not a technical SEO, because it prioritises the issues rather than handing over the grid.
Read the full analysis
Licence versus subscription
Screaming Frog sells one annual licence at £199, with dollar and euro options, and a free edition limited to 500 URLs per crawl. Sitebulb bills monthly: US$18 for Lite with 10,000 URLs an audit, US$42 for Pro with 500,000 URLs, and fifteen percent off for yearly billing. Extra Sitebulb users are £7 a month each.
Where the limit sits
The paid Screaming Frog licence has no published URL ceiling: the constraint is the memory and storage of the machine running it. Sitebulb publishes the ceiling per tier, which makes the cost of a large audit predictable but caps a single crawl at 500,000 URLs on Pro.
Running them
Screaming Frog runs on Windows, macOS on Apple Silicon and Intel, and Linux in several distributions. Sitebulb's desktop editions cover Windows and macOS, and a separate cloud edition runs in the browser with unlimited crawling for teams that would rather not tie an audit to one laptop.
