6 of 12 publish a price · 5 offer a free plan · 5 offer a free trial

  1. Why it ranks here: Search teams auditing many properties get unlimited crawl pages and projects with log-file analysis in Technical SEO, rather than a per-project page ceiling.

    Not a fit if: you want a small rank-monitoring add-on beside audits; seoClarity's separate Rankings package has a 2,000-keyword-query minimum.

  12. Rank12Seobility logo

    Seobility

    Why it ranks here: Teams fixing duplicate content and indexability get browser-based audits and cannibalization checks, with a ceiling of 100,000 subpages.

    Not a fit if: you need a complete crawl beyond 100,000 subpages; Seobility limits larger-site audits to the first 100,000 pages.

Start with seoClarity for unlimited audit pages and projects with log analysis, or Botify, Lumar and Oncrawl for large-site diagnosis joining crawls to other data. JetOctopus Growth includes 500,000 monthly URLs and connects logs, Search Console and GA4. Botify documents million-page crawls and uses server logs to expose bot interactions. Oncrawl adds analytics and Majestic inputs, while Lumar pairs Analyze reports with automated release checks in Protect.

Capacity and diagnosis are separate choices

Sitebulb Pro allows up to 500,000 URLs per audit, with desktop capacity dependent on the computer. Screaming Frog runs on Windows, macOS and Linux and checks more than 300 issues, but its free version stops at 500 URLs. WebSite Auditor adds an HTML or WYSIWYG editor for consultants who also change page content; custom white-label reports require Enterprise.

For an existing SEO suite, compare actual allowances rather than the word unlimited: SE Ranking Core includes 250,000 monthly audit pages; Ahrefs Lite provides 100,000 monthly credits but only 25,000 pages per project. Seobility stops at the first 100,000 subpages on larger sites. seoClarity's Technical SEO package lists unlimited crawl pages and projects with log analysis. JetOctopus's EUR 299 Growth amount requires annual billing; quarterly billing is EUR 399 per month.

How we assessed this shortlist

Products positioned for large-scale technical audits lead, followed by desktop technical investigation tools, then audit functions within broader SEO suites. Within each tier, more documented page-relevant capabilities rank first (technical site crawling and audit, search indexing diagnostics, content research and optimization, reporting and client delivery, named integrations), then published price availability, then product name for remaining ties. Price amount is not a ranking criterion. Products with fewer than six known facts stay below all fuller records. Unknown fields do not count as capabilities; no numeric quality score is assigned.
