Integrity vs LinkOK (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 LinkOK if

• Fits if your site has under 100 pages and a monthly link check is enough
• Works for schools, libraries, nonprofits and open-source projects, which it says it serves free

Look elsewhere if

• Tight if you stay free, at one 100-page scan a month with public reports
• Pricey if your site is big, as daily scans of 100,000 pages are $333 a month billed yearly
• Too light for SEO audits, as it checks links only, with no API or integrations
• Watch out: the terms make every purchase non-refundable, and cancelling takes effect at the term's end

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.

LinkOK

• The free plan scans up to 100 pages once a month, and its reports are public.
• Prices climb with page count and scan frequency: daily scans of 100,000 pages cost $333 a month billed annually ($400 monthly).
• It checks links only; its pages list no on-page SEO, speed or content checks, and no API or integrations.
• The terms say all purchases are non-refundable; a cancellation takes effect at the end of the paid term.

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.

LinkOK

Scheduled scans

Scans the whole site on a fixed schedule, monthly, weekly or daily depending on the plan, without anyone starting a check.

Email reports

After each scan it sends an email with a summary of the results and a link to the full report.

Retries after temporary errors

Links that fail with a temporary error are checked again before they are reported, to reduce false positives.

Unlimited links per site

Every plan, the free one included, checks an unlimited number of links; the limit is the number of pages on the site.

Public or private reports

Reports on the free plan are public; every paid plan keeps them private.

Tiers up to 100,000 pages

Paid tiers run from 100 to 100,000 pages, and larger sites can ask sales for a bigger plan.
