redCacti vs Relinka

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.

Relinka is a WordPress plugin for mapping posts and finding internal-link issues, including broken and orphaned pages. It shows inbound and outbound link counts, a link graph, keyword clusters, and a 0–100 internal-link health score based on orphaned posts, missing outbound links, and broken links. Suggestions include a plain-English reason and use anchor text taken word-for-word from the site's content; suggestions target pages that already exist. Users approve changes before application, and each applied link has a snapshot that can be reverted with one click. The free plugin runs on the site's own server without sending content, links, or analytics to Krafts, and it requires no account or API key. Pro adds AI or semantic suggestions, bulk application, and automatic linking for new posts. Pro AI features are opt-in and use third-party services; the maker says their quality is not guaranteed. Relinka supports Gutenberg and the Classic editor and protects page-builder posts from card insertion. Requirements are WordPress 6.4 or later and PHP 8.1 or later. The free plugin is open source under GPLv2 or later; Pro costs $59 a year for one site.
