Wrendex is a continuous technical SEO auditing platform. It crawls your site on whatever schedule you choose, runs 140+ checks, diffs every run against the previous one, and alerts you the moment something regresses.
It covers the usual ground: broken links, redirect chains, soft 404s, canonical and hreflang errors, sitemap and robots.txt problems, missing or duplicate titles and descriptions, heading hierarchy, structured data validation, Open Graph tags, mixed content, HSTS posture and Core Web Vitals page-weight issues. It also runs checks most audit tools don't have: duplicate analytics trackers loaded twice on one page, redundant stylesheets, the same JS library shipped at two versions, and render-blocking resources that overlap each other.
Wrendex has a built-in MCP server and a REST API, so coding agents like Claude Code, Cursor and Codex can run an audit and work through the fix list directly. Alerts go to email, Slack, Microsoft Teams, PagerDuty and outbound webhooks. Reports export to PDF and CSV with optional white labeling.
Pricing is credit based (one credit per page crawled) and starts at $4.99 per month, with top-up packs that never expire. Unlimited sites and unlimited team seats. Data is encrypted at rest and stored in the EU. You can run a free audit on the homepage without creating an account.
