A technical SEO audit tool built for people who run many sites. Check any client's homepage instantly below, then share one-time credits across all clients - about $0.10 per audit, never expire.
Instant, free, no account - the same engine we run on 10+ of our own products.
Most tools charge per seat or per project, so auditing 20 client sites costs as much as a small salary. Kalenux charges per audit instead.
One credit pool across every site in your account. Audit one client or fifty - the credits come from the same place and never expire.
Each client gets a health score and issue list, tracked run-over-run, so you can show "here's what we fixed since last month."
Export any audit to CSV and drop the issues straight into your own client reports, spreadsheets or task tools.
Run a full technical audit the day you take on a client - find the quick wins before you've even pitched the retainer.
Runs in the browser. No per-machine install, no RAM limits on big client sites, nothing for your team to configure.
Buy credits once. No monthly invoice to justify, no auto-renew, no per-seat creep as your team grows.
A full site-wide technical crawl per client, against 180+ checks.
Broken links, redirect chains, broken redirects, orphan pages.
Noindex, canonical errors, pages dropped from the index, sitemap mismatches.
Titles, meta descriptions, Open Graph, JSON-LD structured-data errors.
Real per-URL PageSpeed metrics, slow pages, render-blocking assets.
Hreflang correctness, language mismatches, missing reciprocals.
Sitemap and robots.txt issues that block correct crawling.
Add as many sites as you like. Credits are shared across every site in the account and never expire, so one $49 pack covers around 500 small-site audits spread over whichever clients need them. Verify each client domain once, with DNS, a meta tag or a file upload, then re-audit whenever you want and track health per site from that point on.
Because the pool is shared rather than per-project, taking on a new client costs nothing extra up front. You spend a credit only when you actually run a crawl.
Roughly $0.10 per audit. The packs are $9 for 50 audits, $19 for 150 and $49 for 500, all one-time, and none of them expire. Set against keyword suites at $100 to $250 per month, billed the same whether you run 2 audits or 200, the difference compounds quickly once you are auditing more than a handful of sites.
It does not replace Ahrefs or Semrush. Those are keyword and backlink suites, and that is a different job. Kalenux is the technical-audit piece: what is broken and whether you fixed it. Most agencies use Kalenux for cheap, repeatable technical audits and keep a keyword suite for research, which usually means dropping a seat rather than a whole subscription.
Every audit exports to CSV, so the issue list drops straight into your existing client reports, spreadsheets or task tools without retyping. Combined with per-site health tracking run-over-run, that gives you a concrete before-and-after to show a client what changed since last month.
No credit card to start. One-time credits, no per-seat bill.
