02Pricing compared
Screaming Frog has the cheaper starting point: its free version allows crawls up to 500 URLs. The paid licence is $199 per user per year, equivalent to $16.58 per month when billed annually, for unlimited* URLs and advanced features. Each user needs a separate licence; the asterisk’s qualification is not specified on the vendor's site.
Ahrefs also has a free plan, but it offers limited Site Explorer and Site Audit access. Paid plans start at $29 per month for Starter; the listed Lite plan is $129 per month and includes 100,000 crawl credits monthly and 750 tracked keywords. Ahrefs says annual payment saves up to 17%. Add-ons can raise the bill: Brand Radar AI starts at $199 per month, and extra users cost $40 per month on Lite.
03Features and depth
These products overlap on technical audits, but they cover different ground. Screaming Frog SEO Spider is a desktop website crawler aimed at technical SEO audits. Its free download has a 500-URL limit; a paid licence adds unlimited* URLs and advanced features, though the published product information does not specify which features.
Ahrefs is a broader SEO and AI-visibility platform. Its listed tools include Site Audit, rank tracking, competitor backlink, traffic and PPC research, and keyword discovery. Brand Radar tracks brand mentions, citations and sentiment in AI chatbots. Ahrefs also describes Letaido AI agents for building reports and automating workflows, plus Ask Ahrefs for report-building and workflow help. These capabilities come with plan limits: Lite lists 750 tracked keywords, 150 AI-prompt checks and 100,000 crawl credits per month. Choose the Spider for focused crawling; choose Ahrefs when you also need research and visibility tools.
04Ease of use and learning curve
Screaming Frog’s scope is narrower: it is desktop crawler software for technical audits, with versions listed for Windows, Mac and Linux. The free version is a practical way to assess whether its 500-URL ceiling works for your audits. The published information does not detail setup steps or the learning curve.
Ahrefs combines several SEO and AI-search tools, so there is more to weigh than crawling alone. Its plans set separate limits for keywords, AI-prompt checks and crawl credits, and add-ons carry separate fees. We’d compare the specific tasks and limits you need before choosing a tier; the published product details do not establish which interface is easier to learn.
