Since the launch of crawl comparison in version 15, we’ve been busy working on the next round of prioritised features and enhancements.ĥ years ago we launched JavaScript rendering, as the first crawler in the industry to render web pages, using Chromium (before headless Chrome existed) to crawl content and links populated client-side using JavaScript.Īs Google, technology and our understanding as an industry has evolved, we’ve updated our integration with headless Chrome to improve efficiency, mimic the crawl behaviour of Google closer, and alert users to more common JavaScript-related issues. We’re excited to announce Screaming Frog SEO Spider version 16.0, codenamed internally as ‘marshmallow’.
