Hexometer Review: AI Website Monitoring & SEO Auditing

What Is Hexometer?

Hexometer bills itself as an AI-powered website performance and uptime monitoring tool, and if that phrase makes you a little skeptical, you're not alone. The AI label gets slapped on plenty of underwhelming products. But Hexometer actually delivers a surprisingly useful package that goes well beyond simple ping-based uptime checks.

At its core, Hexometer monitors your website across several dimensions: server response times, DNS configuration, broken links, homepage asset sizes, W3C validation errors, and meta tag quality. It pulls all of this into a clean, responsive dashboard that gives you an immediate snapshot of your site's health. Think of it as a lightweight SEO audit tool combined with a reliable uptime monitor.

Dashboard Overview and First Impressions

Once you connect your website, Hexometer gets to work right away. The dashboard presents a visual mockup of your site across mobile, desktop, and tablet viewports, which is a nice touch for quickly spotting rendering issues.

Below that, you'll find the server response check. After roughly 10 hours of monitoring, the dashboard showed 100% uptime and a response time of 1,331 milliseconds — higher than ideal, but the kind of data point that's useful to track over time. The uptime graph will fill out as Hexometer collects more data, giving you a clear visual of any performance dips or outages.

The domain and DNS check is another standout section. It verifies your IP address, flags missing DMARC records (critical for email deliverability), checks for MX records, and even looks for Facebook domain verification — something you'll want if you're running any paid social campaigns.

Broken Link Scanner and SEO Auditing

Where Hexometer really starts to earn its keep is with the broken link scanner and meta tags analyzer. The broken link scanner crawled 1,299 links and flagged eight that returned errors — links that other scanners had missed entirely. If you've ever dealt with the slow decay of outbound links on a content-heavy site, you know how valuable this is.

The meta tags analyzer digs into your page titles and descriptions across your entire site. In one scan, it identified 15 titles that needed fixing, 247 descriptions that were too long or otherwise problematic, and 51 pages with no meta description at all. That's a goldmine of actionable SEO tasks surfaced in seconds.

Hexometer also runs a homepage assets check, breaking down your CSS, JavaScript, image, and other file sizes. Discovering that your CSS alone weighs 1.7 megabytes — when you expected far less — is exactly the kind of insight that leads to meaningful performance improvements.

Uptime Monitoring vs. Uptime Robot

Hexometer pings your website once per minute to check availability, which puts it on par with paid uptime monitoring services. The natural comparison here is Uptime Robot, one of the most popular free uptime tools available.

Uptime Robot's free plan gives you 50 monitors with five-minute ping intervals and supports email and Slack notifications. Their paid tier ($4.50/month annually) bumps that down to one-minute checks and adds SSL monitoring and SMS alerts. Hexometer matches the one-minute interval but bundles it with all the SEO and performance auditing features.

If all you need is basic uptime monitoring across many sites, Uptime Robot's free plan is hard to beat. But if you're managing a smaller number of sites and want consolidated monitoring plus SEO insights, Hexometer's one-time payment starts to look compelling compared to ongoing monthly subscriptions for separate tools.

Task Management and Auto Repair

Every issue Hexometer identifies becomes an actionable task in the sidebar. DNS records that need adding, broken links to fix, meta descriptions to write or shorten — they all live in a structured task list. As you resolve them, items move from open to resolved, giving you a running log of improvements you've made to your site over time.

Hexometer also includes an auto-repair feature for certain issues, though your mileage may vary. In testing, none of the 298 flagged tasks qualified for automatic repair, meaning the fixes required manual attention. Still, having everything organized in one place with clear guidance on what needs fixing is a significant workflow improvement over juggling multiple tools and spreadsheets.

The alerts feed rounds things out by logging events like newly detected 404 errors. You can set up email and SMS notifications, with Trello and Slack integrations planned for the future.

Pricing and Who This Deal Is For

The AppSumo lifetime deal structure is straightforward but has drawn some criticism for its site limits. One code at $49 covers a single website. Two codes unlock three sites, five codes get you three, ten codes cover four, and fifteen codes support five websites. The community was hoping for more generous limits, and it's worth watching to see if the founders adjust these numbers.

This deal is clearly aimed at individuals and small teams running a handful of websites. If you've got one to five sites and you're not already paying for a comprehensive SEO tool like Ahrefs or SEMrush, Hexometer fills a useful gap at a one-time cost. You get uptime monitoring, broken link detection, meta tag auditing, and performance analysis bundled together.

For agencies managing dozens or hundreds of sites, this isn't the right fit. The per-site pricing simply doesn't scale for that use case. But for the solo website owner or small business operator, spending $49 to $100 for lifetime access to this level of monitoring is a reasonable investment.

Final Verdict: 8.1 out of 10

Hexometer earns an 8.1 out of 10. The user interface is polished, snappy, and well-designed. The data it surfaces is genuinely useful — broken links that other tools missed, a clear picture of your site's asset bloat, and a structured list of SEO improvements you can work through methodically.

The main knock against it is the limited number of sites per plan, which has frustrated the AppSumo community. If you can live within those limits, though, you're getting a quality product that combines several monitoring functions into one platform. It's a better tool than many people are giving it credit for, and it deserves a serious look if consolidated website health monitoring is something you need.
