Screaming Frog is a desktop application that crawls websites like a search engine. SilverGecko is a cloud-based tool that audits individual pages instantly. One goes wide, the other goes deep on a single page.
What Screaming Frog does better
Full site crawling
Screaming Frog crawls every page on your site. Find broken links, redirect chains, duplicate titles, missing tags, and orphan pages across thousands of URLs. SilverGecko audits one page at a time.
Custom extraction
Screaming Frog can extract any HTML element using CSS selectors or XPath. Scrape prices, dates, author names, or any custom data point across your site.
Integration with other tools
Connects to Google Analytics, Search Console, PageSpeed Insights, and Ahrefs for enriched crawl data. SilverGecko is standalone.
JavaScript rendering
Screaming Frog can render JavaScript to audit SPAs and dynamic content. SilverGecko fetches the initial HTML response.
No usage limits (paid version)
The paid version ($259/year) has no crawl limits. The free version crawls up to 500 URLs.
