DYNO Mapper vs Screaming Frog SEO Spider (2026): which should you pick?

Pick DYNO Mapper if

• Fits if you're an agency or UX team mapping a site before a redesign
• Works for organizations that need WCAG and Section 508 accessibility checks

Look elsewhere if

• Skip it if you want the audit, accessibility tests or rank tracking on Lite, as they start at Pro, $49 a month billed yearly
• Pricey if you need scheduled crawls or private site crawling, which start at Standard, $99 a month billed yearly
• Too light for large sites, as crawls stop at 2,500 to 25,000 pages and more needs Enterprise
• Tight if you're a team on Lite or Pro, which are 1 user each
• Watch out: monthly plans have a one-month minimum term and annual plans a one-year minimum

Pick Screaming Frog SEO Spider if

• Fits if you're a technical SEO who audits large sites from your own computer
• Works for sites under 500 URLs, which the free version crawls with no time limit

Look elsewhere if

• Skip it if you want keyword research, rank tracking or backlinks, as it only crawls
• Not for you if you'd rather not learn technical SEO terms, XPath or regex
• Tight if your computer is short on memory or storage, since crawl size depends on it, and there's no web or phone version
• Pricey if a team needs it: licences are $279 per user a year, so two people need two
• Watch out: the free version can't save crawls, render JavaScript, schedule audits or connect to Google data

DYNO Mapper
