What Screaming Frog is for
Screaming Frog is a desktop crawler that gives a technical SEO complete control over one crawl of one site, and it is very good at that job. Most people reading this already have it open.
What Rankelle is for
We crawl on a schedule across a portfolio, group findings into causes with a confidence attached, keep watching the affected URLs so a fix landing is detected without anyone reporting it, and then measure the result.
Where they overlap
Crawling and issue detection. For a deep one-off investigation of a single site, a desktop crawler you drive by hand will always beat a scheduled one.
Running both
- Reach for Screaming Frog when you need to interrogate one site in depth, right now.
- Leave the ledger running for the month-to-month state of every client.
- Export the affected URL list from a cause when you want to take it back into a desktop crawl for a closer look.
Why would I want a hosted crawler as well?
Because the desktop crawl is a snapshot with a person attached. Nothing on your laptop notices a template regression on a Tuesday, or that the fix you asked for in June finally shipped in August.
Can I import a Screaming Frog crawl?
No. Our verdicts depend on crawls taken by our own crawler on a known schedule, and importing someone else's snapshot would put an unverifiable input under a claim we publish to clients.
Checked in September 2026 against Screaming Frog's own public description of the product. Vendors ship on their own schedule; if something here has gone out of date, tell us and we will correct the page rather than leave a false statement with our name on it.
