In their own words
DefiniteSEO
DefiniteSEO brings WordPress SEO tools together with an online audit service for examining site health, AI-search visibility, backlinks, and content. Audits cover technical and on-page SEO, content, links, security, performance, accessibility, and DNS, with fixes prioritized. Its AI-visibility tools check whether ChatGPT and Google AI Overviews cite a site and assess pages for readiness for AI search. The WordPress plugin can apply individual or bulk fixes, schedule automated changes, and reverse changes within 30 days. It works with Classic Editor, Gutenberg, Elementor, and WooCommerce, and can import settings from Yoast or Rank Math. The AI SEO Writer can publish to WordPress or provide content for another CMS. Free options include an unlimited-sites plugin and an audit plan for one project and 50 pages per month. Paid plans are listed from $4.99/mo (annual). The audit service is not a standalone classic rank-tracking or keyword-research suite.
Open SEO Crawler
Open SEO Crawler is a free, self-hosted, open-source tool for auditing websites for technical SEO issues. It checks titles, meta descriptions, H1s, canonicals, structured data, redirects, HTTP errors, indexability, hreflang, mobile viewports, mixed content, images and security headers. It detects numerous CMS platforms, including Shopify, WordPress, Webflow, Wix, Squarespace, Kajabi, Ghost, Drupal, HubSpot and Joomla, then applies crawl recommendations. Optional Playwright rendering supports JavaScript-heavy sites, while compare mode identifies content absent from raw HTML.
Bulk reports can be exported to XLSX, and sitemap export is available. Default settings allow 1,500 pages, five workers, a 0.4-second per-host delay and depth 10; the page cap can be changed to unlimited. The crawler runs locally without accounts, telemetry or API calls, though it contacts target sites and checks GitHub for updates when requested. Installers are documented for Linux, macOS 11 or newer, and Windows 10/11. The project uses the MIT license.
