If you need a focused technical crawl, pick Screaming Frog SEO Spider. If you want site auditing alongside rank tracking, keyword research, backlink analysis and outreach, pick SEO PowerSuite, with WebSite Auditor as its audit tool. Screaming Frog is £199 for one user for one year, and WebSite Auditor is $149 a year for Professional or $359 for Enterprise, checked November 9, 2026.
Both are desktop applications with free versions limited to 500 URLs or resources. Screaming Frog is the narrower crawler, while WebSite Auditor fits a wider SEO workflow. The better choice depends on whether your work ends with a crawl report or continues into rankings, content, backlinks and client reporting.
Start with the largest site you need to crawl, then weigh JavaScript needs, integrations, reporting, user access and renewal terms.

Which tool fits the site audit job in front of you?
Start with the outcome you want after the crawl. Screaming Frog suits a technical SEO audit where you hunt for broken links, redirects, metadata problems, duplicate pages, hreflang issues, structured-data problems, sitemap issues and accessibility concerns. Its crawl settings, rendered-page analysis, crawl comparisons, custom extraction, visualizations and exports keep the focus on examining a website.
WebSite Auditor suits a wider SEO process. Its audit covers crawlability, indexability, redirects, duplicate content, on-page factors, internal linking, site architecture, robots.txt, orphan pages, JavaScript-rendered content and custom search. It adds content optimization, competitor on-page analysis, project saving, scheduled SEO tasks and report tools.
If you are a freelancer handling occasional technical work and already use other tools for rankings, backlinks or content research, Screaming Frog is the clearer fit. If the site audit is one part of a broader SEO platform for you, WebSite Auditor is.
SEO PowerSuite also includes Rank Tracker for rankings and keyword research, SEO SpyGlass for backlink analysis and LinkAssistant for outreach. Those are separate applications, so do not assume every SEO PowerSuite feature sits inside WebSite Auditor.
What can you test in the free versions before paying?
Run both free versions against a representative site before choosing. A small homepage crawl can hide the limit that affects a larger business site, a client project or a site with many resources. Note how many URLs or resources the crawl reaches, which reports you need and whether JavaScript pages behave as expected.
Screaming Frog's free version crawls up to 500 URLs per crawl with no time limit. It includes broken-link and redirect discovery, title and metadata analysis, robots and hreflang checks, duplicate-page discovery, XML sitemap generation, site visualizations, structured-data checks, spelling and grammar checks and basic reporting.
It restricts advanced configuration, saved and reopened crawls, JavaScript rendering, custom extraction, API integrations and scheduling. If any of those are part of your normal workflow, the free crawl shows you the interface but not the full process you would pay for.
WebSite Auditor's free version is also available indefinitely and crawls and audits 500 URLs or resources. It includes in-app content optimization, as-you-type recommendations, competitor on-page strategy analysis, optimized-page export, project saving, scheduled SEO tasks, custom search, clipboard copying and report printing. The free license still has project and reporting restrictions, and the paid editions set how much crawling, saving, exporting and client reporting you get.
How do Screaming Frog's crawler features and desktop requirements affect your work?
If your audit begins with finding technical issues, Screaming Frog gives you a direct crawl-first workflow. It examines links, redirects, metadata, hreflang, structured data, XML sitemaps, accessibility signals and page relationships. Site visualizations show how pages connect, and crawl comparisons let you check one crawl against another after a release or migration.
JavaScript rendering is a paid feature. In that mode Screaming Frog uses a headless Chromium browser to render pages and extract content and links from the rendered HTML. That matters when the page source lacks the links or content a visitor sees after scripts run. Rendering also needs more local resources, so the size and behavior of the site affect crawl time and capacity.
Screaming Frog supports Windows, macOS, Ubuntu and Fedora. The minimum specification is a 64-bit operating system and at least 4 GB of available RAM, and the vendor recommends an SSD and more memory for large crawls.
That hardware requirement is part of the product choice, because a large crawl depends on your computer, memory, storage and rendering mode. Screaming Frog does not guarantee a particular crawl speed.
The free version is useful for a smaller technical check. A paid license becomes practical when you need JavaScript rendering, saved crawls, API connections, scheduled work or repeated reports.
How does WebSite Auditor handle auditing, optimization and reporting?
Choose WebSite Auditor when you want the crawl to lead directly into on-page work. Its audit dashboard groups issues involving crawlability, indexability, redirects, duplicate content, on-page elements, internal links, site structure, resources, robots.txt, orphan pages and JavaScript-rendered content.
The practical difference is that it connects the technical audit with content optimization. As-you-type recommendations, competitor on-page strategy analysis, custom search, optimized-page export and robots.txt and XML sitemap tools help you move from spotting an issue to reviewing the page changes that may address it.
Projects and reports are part of the workflow too. The free version includes project saving and scheduled SEO tasks, while the paid editions remove the 500-URL crawl limit. Professional adds unlimited crawling and auditing, unlimited project saving and printed reports with watermarks.
Enterprise is meant for client work. It adds saving, emailing and scheduling reports, along with CSV, SQL and HTML data export. That can cut manual work for a freelancer or agency, as long as the edition matches the reporting process you actually use.
WebSite Auditor does not fix a website or guarantee indexing, rankings or traffic. Its recommendations are inputs for the site owner or developer. Before relying on it for a client deadline, check the current support channel and confirm that the scheduled task and report format behave as you need.

Which tool handles JavaScript, integrations and scheduled audits better?
Both products document JavaScript crawling, but the surrounding workflow differs. Screaming Frog's paid rendering mode uses headless Chromium to retrieve content and links that appear after JavaScript runs. WebSite Auditor documents JavaScript execution and crawling of dynamically generated content, including rendered content and links.
Screaming Frog has the clearer documented integration list for external measurement data. It connects with Google Analytics, Google Search Console and PageSpeed Insights. Search Console data can include clicks, impressions, click-through rate, position and URL Inspection data for up to 2,000 URLs per property per day. PageSpeed Insights can bring Lighthouse and related performance data into a crawl.
WebSite Auditor's strengths are its audit dashboard, content optimization, competitor on-page analysis, site architecture tools, custom search, robots.txt and sitemap work and client reporting. If Analytics, Search Console or performance data must be part of your workflow, confirm the specific Google connection and edition with Link-Assistant before you buy.
Both tools document scheduling. Screaming Frog can run crawls at chosen intervals and export data, including workflows with Google Sheets and Looker Studio. WebSite Auditor can schedule project rebuilds, data updates, result exports and report publication.
Because both run locally, scheduled work depends on your computer and network. It is not a hosted service, so test the schedule before you assign recurring client work.
What does each license cost, and what will it renew at?
These are the full published terms, checked November 9, 2026. Screaming Frog publishes its paid price in GBP, while WebSite Auditor publishes in dollars, so confirm the converted total, taxes and card charge at checkout.
Screaming Frog's paid license is for one authorised user, who may install it on multiple devices. The £199 is not a fixed dollar amount, because your payment provider or card issuer may convert it. If you are weighing the wider suite, see SEO PowerSuite's current plans and confirm the final checkout total before paying.
WebSite Auditor Professional fits in-house use when you need unlimited crawling and project saving but not client-oriented report delivery. Enterprise fits client work where emailed, scheduled and exported reports are part of the service, so the price gap follows your workflow, not only crawl size.
Screaming Frog returns to its restricted free version when the paid license expires. WebSite Auditor's one-year license renews automatically unless cancelled, and its agreement says renewal uses the price displayed at that time.
For the wider bundle, see SEO PowerSuite Pricing: Free, Professional and Enterprise Explained. If you only need the free-versus-paid decision, read SEO PowerSuite Free vs Paid: What the Free Version Can Do.
How do user limits, refunds and practical tradeoffs change the choice?
Choose based on who will run the software and how often the work repeats. Screaming Frog's license is for one user, though that person can use multiple devices, and additional users need additional licenses. SEO PowerSuite's Professional and Enterprise licenses are also one-user, so confirm whether the person doing the work is an employee, contractor or agency partner.
Screaming Frog publishes a full-refund window of 14 days after purchase and gives no pro-rata refunds for unused license time. The published Link-Assistant policy for WebSite Auditor says cancellation does not create a refund and access continues through the paid term. You cancel through the 2Checkout account.
That makes renewal control a practical difference. Screaming Frog normally expires unless you selected auto-renewal, while WebSite Auditor renews automatically unless you cancel before the new term. Read the current refund terms at checkout, save your payment-provider account details and cancel there before renewal if needed.
The main Screaming Frog tradeoff is focus: it is a crawler built for technical inspection, so ranking, backlink and outreach work sits outside it. The main WebSite Auditor tradeoff is edition choice, because free and Professional may be enough for personal or in-house work while client reporting and exports need Enterprise.
Neither tool proves that a recommendation will improve performance, so test changes and confirm the result on the live site.
Which SEO PowerSuite or WebSite Auditor guide should you read next?
Pick the next page by the decision you still have to make. If you are unsure whether the wider bundle fits, read the SEO PowerSuite review and look at how WebSite Auditor, Rank Tracker, SEO SpyGlass and LinkAssistant divide the work.
If WebSite Auditor is your likely choice, read the WebSite Auditor review, then match its audit, optimization, scheduling and reporting functions to the edition you need.
For the immediate next step, run both free versions against the same representative site and note the URL limit, JavaScript behavior, integrations, report needs, user count and renewal arrangement. Then choose Screaming Frog for a focused crawler or WebSite Auditor for a broader SEO and reporting workflow.
