Where nanoSEO is stronger

✓No installing, no manually starting anything – the crawl runs automatically in the background and you get a finished report instead of a raw data table.
✓Field-level change history between two scans, including old and new values – Screaming Frog doesn't automatically diff crawls against each other.
✓AI-powered, prioritized recommendations instead of raw diagnostic data that still needs to be interpreted.
✓Runs completely independent of your hardware, since the crawl takes place entirely on nanoSEO's servers.

Where Screaming Frog is stronger

✓Extremely granular, free-form data extraction via XPath, CSS selector, or regex – if you need very specific, custom crawl data, it's hard to beat.
✓A one-off annual license with no ongoing page-based billing, but unlimited crawls – potentially cheaper for very large, irregular crawl needs.
✓Runs entirely locally: raw data never leaves your machine, full control over storage location and data processing.
✓An established standard among technical SEOs, with a very large feature set for in-depth analysis (e.g. log file analysis as a separate tool from the same product family).

No, not currently. nanoSEO crawls your website on its own, independently.

Yes, for ongoing automated monitoring without local installation. If you regularly need very specific data extraction via XPath or regex, Screaming Frog remains the more flexible tool for that – many teams use both tools in parallel.
