In their own words
A1 Website Analyzer
A1 Website Analyzer crawls sites to identify broken links and redirects, examine internal linking, check SEO, and find duplicate page content. It can scan websites on the internet, localhost, a local file system, or a local area network. Technical checks cover canonical and robots settings, keyword content, spelling, and HTML and CSS validation. Link reports include internal and outgoing links, pages that link internally, and calculated importance scores. Users can import Apache logs, Google Webmaster Tools CSV files, and text files, then export scan data as XML or CSV. Command-line parameters and Windows Task Scheduler can automate scans. The software is available for Windows and macOS. Free mode permits 500 page URLs and 500 imported URLs per website. Professional is listed at $49 a month, with no fixed crawl limit and command-line support. The maker lists a fully functional 30-day evaluation period and a 30-day satisfaction guarantee. The maker also says support is free before and after purchase and usually responds within 12 hours.
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.
