In their own words
Screaming Frog SEO Spider
Screaming Frog SEO Spider crawls websites to audit more than 300 SEO issues and support improvements to search performance and user experience. It finds broken links and server errors, checks redirects, and flags page titles and meta descriptions that are missing, duplicated, or too long. For JavaScript-heavy sites, it can render pages with its integrated Chromium WRS, including sites using Angular, React, and Vue.js. Data extraction supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, with link-metrics integrations for Majestic, Ahrefs, and Moz. Crawls can be scheduled, automated from the command line, exported to destinations such as Google Sheets, and compared across runs or between staging and production. The free version costs nothing and allows 500 URLs per crawl; saving crawls, configuration, and advanced features are restricted. The paid version costs $279 a year per licence, with unlimited crawl size subject to allocated memory and storage. It runs on Linux, macOS, and Windows.
SpiderNow
SpiderNow is a website crawler that extracts site data and performs real-time audits. Users can scan a page, folder, or full website. Its checks cover broken links and images, JavaScript sites, redirects, duplicate content, internal and external links, and robots directives. PageSpeed Insights analysis includes Performance, Accessibility, Best Practices, and SEO audits for pages.
The product also has tools to minify and beautify HTML, JavaScript, and CSS, generate critical CSS, and convert images to WebP. AI-powered tools can recommend or implement content changes subject to the site's add-on terms; content improvement uses Grammarly for spelling and grammar corrections. SpiderNow is described as suitable for SEO agencies, web developers, digital marketers, and businesses. It is available on web, Android, iOS, and as an extension, and requires no software download. Crawl size depends on device RAM because processing uses device memory. The free plan includes 10 single-page scans per month, 5 scan details and issue views, and 5 page metric scores. Paid plans start at $6.99 a month.
