In their own words
Lighthouse
Lighthouse is an open-source automated tool for auditing web page quality. Given a URL, it runs audits covering performance, accessibility, best practices, SEO, and other areas, then produces a report with results and references on the audits and how to address failures. It is aimed at web developers seeking relevant, actionable guidance. Lighthouse runs in Chrome DevTools, from the command line, as a Node module, or through a web interface without installation. DevTools can audit pages requiring authentication; the Chrome extension cannot audit authenticated pages or local sites. Reports can be produced as JSON or HTML, and the command-line tool also supports CSV. Stack packs add platform-specific recommendations, while plugins allow domain experts to contribute audits and report categories. Lighthouse can be integrated into continuous integration, and Lighthouse CI can help prevent regressions. Reports can be viewed online or shared with Lighthouse Viewer using report JSON. The CLI and Node workflows require Google Chrome, and the repository specifies Node 22 (LTS) or later. Its first CLI run asks about anonymous runtime exception reporting; opting out does not affect use.
WebSite Auditor
WebSite Auditor is software for technical and on-page SEO auditing and website optimization. It crawls site architecture and checks HTTP status codes, broken links, HTML errors, titles, meta descriptions, and link factors. Its content module provides page-specific recommendations, keyword-density guidance, and HTML-element analysis; pages can also be compared with 10 top-ranking competitors. The software generates Google-friendly XML sitemaps, can upload them through FTP and submit them to Google, Yahoo!, Bing, and Ask, and creates and manages robots.txt files via FTP. It supports 750 search engines and UTF-8 content in any language. Google Analytics traffic data and Search Console metrics can be added to projects, with clicks, impressions, CTR, and average rank available for export. The free license covers 500 URLs and one project, with no paid report exports. Professional costs $149 a year; Enterprise costs $359 a year. It runs on Linux, macOS, and Windows. The maker offers a seven-day trial of paid SEO PowerSuite features when requested from support.
