Free desktop SEO crawler and website auditor by SEO PowerSuite. Unlimited site crawling, technical SEO auditing, content analysis, and one-click export. Windows/Mac/Linux.
WebSite Auditor is a desktop-based technical SEO crawler and site audit tool developed by SEO PowerSuite (Link-Assistant.com), offered as a free download with unlimited site crawling capabilities. Part of the SEO PowerSuite toolkit—alongside Rank Tracker, SEO SpyGlass, and LinkAssistant—WebSite Auditor handles on-page technical auditing, content optimization analysis, internal linking structure review, and site visualization. It runs on Windows, macOS, and Linux.
Unlike cloud-based crawlers (Screaming Frog, Sitebulb, Lumar) that charge monthly subscriptions, WebSite Auditor's free version allows unlimited page crawling with no monthly cap—making it particularly attractive for agencies auditing large enterprise sites or freelancers doing occasional deep technical audits without a recurring SaaS cost. The paid SEO PowerSuite Professional license unlocks full reporting and export capabilities.
WebSite Auditor is not suited for teams that need cloud-based collaboration, real-time monitoring, or integrated backlink analysis alongside their crawler—it is a powerful standalone desktop auditor, not an all-in-one cloud SEO platform.

WebSite Auditor's free version crawls unlimited pages—no monthly cap, no page limit, no credit system. This is the tool's biggest competitive advantage against cloud crawlers like Screaming Frog (free version capped at 500 URLs) or SaaS platforms that charge by pageview. For agencies auditing large enterprise sites with 50,000+ pages or freelancers doing irregular deep audits, the unlimited free crawl capability dramatically reduces audit costs.
The platform checks over 500 on-page and technical SEO factors: broken internal and external links, redirect chains, duplicate content (thin and identical pages), Core Web Vitals integration, structured data validation, hreflang implementation, XML sitemap issues, robots.txt analysis, and page speed data via the Google PageSpeed API. This comprehensive coverage makes WebSite Auditor comparable in technical depth to paid cloud crawlers at $100+/month.
Beyond technical auditing, WebSite Auditor includes a content optimization module that analyzes on-page SEO for target keywords—examining keyword density, heading structure, TF-IDF analysis, and competitive content benchmarking. This allows technical auditors to also flag on-page content issues without needing a separate content optimization tool.
Occasional technical audits: free plan is sufficient. Freelancers delivering audit reports to clients: $299/year Professional (includes all 4 SEO PowerSuite tools). Agencies with white-label report requirements: $699/year Enterprise. The annual license is a one-time commitment with no monthly billing, which simplifies budget planning compared to SaaS subscriptions.
Prices subject to change. Check official pricing page.
Pro tip: Run a crawl comparing your site structure with the XML sitemap—WebSite Auditor will flag pages crawled but not in the sitemap and vice versa, revealing indexation gaps that often cause significant organic traffic losses at enterprise scale.
WebSite Auditor has been part of the SEO PowerSuite toolkit for years and maintains strong reviews in the technical SEO community, particularly among consultants and agencies who value desktop control and unlimited crawling. It's frequently cited as the best free alternative to Screaming Frog for large-site auditing. The bundled Professional license pricing ($299/year for all 4 SEO PowerSuite tools) is regularly praised as exceptional value compared to individual SaaS subscriptions.
What users praise: Unlimited free crawling, 500+ technical checks, comprehensive on-page analysis, excellent price-to-value on Professional plan.
Common frustrations: Desktop-only (no cloud/collaboration), report export requires paid license, no continuous monitoring or alerts.

Yes — the free version allows unlimited site crawling with no page cap. Full report export and scheduled auditing require the Professional ($299/year) or Enterprise ($699/year) license, which also includes all other SEO PowerSuite tools.
Both are desktop SEO crawlers. WebSite Auditor's free version crawls unlimited pages (Screaming Frog limits free version to 500 URLs). Screaming Frog has a stronger reputation for JavaScript rendering and advanced crawl configuration. Both are capable for professional technical SEO auditing; the choice often comes down to workflow preference and budget.
Yes — unlimited crawling on the free version reduces per-client audit costs significantly. The Professional plan's white-label PDF reports (on Enterprise) enable branded client deliverables. The desktop-only nature limits real-time team collaboration compared to cloud tools.
Yes — WebSite Auditor supports Windows, macOS, and Linux as part of the SEO PowerSuite cross-platform desktop toolkit.
