In their own words
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.

Paid plans start at $6.99 a month.
