In their own words
LibreCrawl
LibreCrawl is a web-based SEO crawler for auditing and analyzing websites. It checks technical areas such as meta tags, schema markup, hreflang, social tags and PageSpeed metrics. Playwright rendering lets it crawl JavaScript sites built with React, Vue, Angular or Next.js, in headed or headless mode. The maker says memory profiling and virtual scrolling support stable crawls of more than one million URLs. Results can be exported as CSV, JSON or XML, with custom field selection and no stated export restrictions. LibreCrawl is MIT-licensed and can be self-hosted. Its REST API supports crawl control, settings and exports, and uses session-based authentication for every endpoint. Guest API users are limited to three crawls per 24 hours, tracked by IP address. The maker says the software does not track users, collect analytics or send crawl data back to itself, and encourages self-hosting for privacy. It is free, with no subscriptions or paid tiers. The maker directs bug reports and feature requests to GitHub Issues and discussions to GitHub Discussions.
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.
