Instant, free, no account needed - the same engine we run on 10+ of our own products.

Why pay monthly to audit your own site?

Almost every SEO crawler now bills monthly or annually - even the "cheap" ones. You end up paying year-round for a tool you open a few times a month.

Subscriptions add up

$100-250/mo suites, or "budget" tools at £95/mo and annual licences. That's hundreds to thousands a year, whether you run 2 audits or 200.

Lifetime deals overcharge upfront

One-time deals like Screpy ($59) or Ubersuggest LTD ($290+) make you pre-pay for unlimited access you may never fully use.

Kalenux: pay per audit

One-time credits from $9. A few sites cost a few dollars. Credits never expire, shared across all your sites. Buy more only when you run out.

Titles, meta descriptions, Open Graph, and JSON-LD schema errors that block rich results.

Real PageSpeed metrics per URL, slow pages, render-blocking assets.

International SEO

Hreflang correctness - missing reciprocals, language mismatches, broken hreflang.

Sitemaps & robots

Sitemap and robots.txt issues that stop search engines crawling you correctly.

One-time credits, lifetime deals and what you get

An SEO audit tool without a subscription

Kalenux uses one-time credits instead of a monthly bill. You pay once, from $9 for 50 audits, and buy again only when you actually run out. There is no card kept on file and nothing renews on its own, so an idle month costs you nothing.

Pay-per-audit compared with a lifetime deal

Most SEO lifetime deals ask for $59 to $990 upfront in exchange for unlimited access you may never fully use. That is still pre-paying for capacity, just in one lump instead of monthly instalments. Credits work the other way round: you are charged per audit, so a handful of sites costs a few dollars in total and you never buy headroom you will not touch.

Credits that do not expire

Buy a pack once and use it whenever you like, this month or next year. There is no monthly reset and no use-it-or-lose-it clock. Credits are also shared across every site in your account, which is what makes the model work for agencies and freelancers auditing multiple client sites out of a single pool.

What each audit checks

A full site-wide technical crawl against 80-plus checks: broken links, redirects, canonicals, hreflang, structured data, sitemaps and indexability, plus real PageSpeed and Core Web Vitals per URL. It is a focused technical audit tool rather than a keyword-research suite, which is precisely why it can be priced this way.

Switching from a monthly SEO tool

If you only use your SEO suite for the technical audit, you're paying $100+/month for a fraction of what it does. Here's how to switch the technical piece to pay-once.

1Work out what you actually use it for

Most people open their SEO suite for two things: keyword research and technical audits. If you rarely touch the keyword side, you're paying a full subscription for the audit feature alone - which is exactly what a dedicated pay-once tool replaces.

2Keep keyword research, move the audit

You don't have to give up your keyword tool. Many users keep a cheaper keyword option (or a free one) and move the technical audit to one-time credits - cutting the expensive subscription entirely while keeping every capability they relied on.

3Run a baseline before you cancel

Audit your sites once with Kalenux (free to start) and export the reports. Once you've confirmed it covers your technical checks, cancel the subscription. Your one-time credits sit there for the next audit - no clock running.

Audit your site free, then pay once

No credit card to start. No subscription, ever.
