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

Pick Integrity if

• Fits if you have a Mac and want a free broken-link check of a personal site
• Makes sense if you'd rather pay $20 or $59 once than a monthly fee

Look elsewhere if

• Skip it if you're on Windows or want it in a browser, as it's macOS only
• Tight if you stay free, with no export, search, sitemaps or SEO checks, and business use asked to pay
• Not for you if you need scheduled scans, logins or client reports, which need the maker's $149 Scrutiny
• Watch out: licences are per user, so a team buys one each

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

Integrity

• It runs only on macOS 11.5 or later; older versions remain for older Macs.
• The free edition is for personal use and cannot export results; business users are asked to buy Plus or Pro.
• Scheduled scans, login-protected sites and client reports need Scrutiny, the maker's $149 app.
• Licences are per user; there is no web or Windows version, only a paid online scan service.

Screaming Frog SEO Spider

• Licences are per user and last one year; two people need two licences.
• It is a desktop app, so crawl size depends on the computer's memory and storage.
• The free version cannot save crawls, render JavaScript, schedule audits or connect to Google data.

Integrity

Link checking

Crawls a site and checks every internal and external link and image, including soft 404s, with problems highlighted in color.

XML sitemap export

Plus and Pro export an XML sitemap, optionally with images and PDF files, with rules for priority and change frequency.

SEO warnings

Integrity Pro flags missing titles and descriptions, thin content, keyword-stuffed pages, images without alt text and mixed content.

HTML validation and spelling

Pro checks the HTML of each page as it scans and runs a spell check using the Mac's own dictionary.

Search, filter and export

The paid editions let you search and filter scan results and export them, and keep settings for many sites.
