In their own words
Core+ Links
Core+ Links is a self-hosted WordPress plugin that finds and manages internal links using a local index of site content. In the Gutenberg block editor, its sidebar ranks possible destinations with eight weighted signals and shows match strength. You can revise anchor text, insert a suggestion in one click, or dismiss it. Keyword rules scan pages for matches that you review before applying. A change history can undo one edit, a complete run, or links created by a keyword rule. Reports identify orphan pages without inbound links and underlinked pages with fewer links than their importance calls for. Link Health flags links to unpublished, trashed, or missing pages, but does not inspect external URLs over HTTP. Indexing, ranking, auto-linking, and Link Health run on your server and database. The free plan is permanent and includes background indexing and scheduled reindexing. Requirements are WordPress 6.6+, PHP 7.4+, and Gutenberg. Upcoming Pro plans have no listed prices.
redCacti
redCacti is a web service for website health monitoring and SEO analysis. Its crawler finds broken internal and external links, orphan pages, and internal-linking gaps; it can also identify redirect chains and loops. Scheduled crawls can run daily, weekly, or monthly and follow robots.txt directives. Audits cover metadata, Open Graph and Twitter Card tags, Schema.org structured data, image alt text, and SSL certificates. For internal linking, the service suggests source and target pages, anchor text, similarity scores, impact labels, and context. Users can paste draft content for proposed link placements, but a team must review and add those links in its CMS. redCacti tracks health scores and crawl snapshots, and scheduled crawls can notify users of new issues. It says it works with any CMS, naming WordPress, Webflow, Shopify, custom stacks, and headless websites. The free plan is free for one website and up to 1,000 pages, with up to 30 results visible. Pro costs $19 a month billed monthly; Agency costs $39 a month billed monthly.
