Honest Comparison
An honest comparison to help you pick the right performance monitoring tool. Both are solid options. Here's where they differ.
GTmetrix is an established performance testing tool with a large user base and mature feature set. It's Lighthouse-based (like us) and offers solid monitoring at affordable prices.
Ahoj Metrics is newer, built for simultaneous multi-region testing. Where GTmetrix tests one location at a time, Ahoj Metrics tests up to 18 regions in parallel in about 2 minutes.
If you need quick single-location tests with detailed waterfall charts, GTmetrix is great. If you need to understand how your site performs globally and want all your regional data in one audit, Ahoj Metrics is built for that.

We believe in being honest. Here's where GTmetrix has the edge:
GTmetrix offers 22 locations (25 on PRO plans) compared to our 18. If you need testing from a specific location we don't cover, GTmetrix might have it.
GTmetrix provides detailed waterfall charts showing exactly how each resource loads, plus a filmstrip view of the page rendering process. These are valuable debugging tools that Ahoj Metrics doesn't offer yet.
GTmetrix starts at $5/month (Micro plan). Our cheapest paid plan is $35/month. If you're a solo developer who just needs a few extra tests and basic monitoring, GTmetrix is cheaper.
GTmetrix has been around for years. Their reporting is polished, their API is well-documented, and they have a large community. We launched in January 2026.
GTmetrix can record a video of your page loading, which is useful for presentations and client reports.
Here's what Ahoj Metrics does differently:
This is the core difference. When you run an audit on Ahoj Metrics, it tests from multiple regions at the same time. One click, 18 regions, ~2 minutes. On GTmetrix, you'd need to run 18 separate tests manually (or via API) and piece the results together yourself.
Your dashboard shows how performance varies across regions side-by-side. Spot the CDN misconfiguration that's slowing down Asia. See that your European users get a perfect score while South America struggles. This is what Ahoj Metrics is built for.
Our Studio plan ($69/month) includes 20 monitors, 10 team members, and unlimited data retention. Getting equivalent coverage on GTmetrix requires the Growth plan ($40/month) plus additional monitoring slots.
One audit = one audit, regardless of how many regions you test. GTmetrix counts individual tests, so testing from 5 locations uses 5 tests from your weekly allowance.
Ahoj Metrics includes a Field Data lookup powered by Google's Chrome User Experience Report. See p75 values and Good/Needs Improvement/Poor distributions for LCP, INP, CLS, FCP, and TTFB — what real Chrome users actually experience. GTmetrix has no CrUX integration.

| Audits/Tests | 100 audits/month | 150-175 tests/week |
| Monitoring | 5 monitors | 3-6 monitors |
| Monitoring Frequency | Hourly/Daily/Weekly | Daily or Hourly |
| Regions per Audit | Up to 5 | 1 per test |
| Data Retention | 90 days | 6 months |
| API Access | Coming soon | Yes |
| Ahoj Metrics | GTmetrix | |

| Price | $69/month | $40/month |
| Audits/Tests | 500 audits/month | 250 tests/week |
| Monitoring | 20 monitors | 12 monitors |
| Team Members | 10 | Add-on |
| Regions per Audit | Up to 5 | 1 per test |
| Data Retention | Unlimited | 6 months |
Keep in mind that a single Ahoj Metrics audit tests from multiple regions simultaneously. A 5-region audit on Ahoj Metrics counts as 1 audit. The equivalent on GTmetrix would count as 5 separate tests.

You want GTmetrix for deep single-page debugging (waterfall, filmstrip) and Ahoj Metrics for ongoing global monitoring.

Start FreeAlready using GTmetrix? Ahoj Metrics works great alongside it. Use GTmetrix for debugging, Ahoj Metrics for global monitoring.
Yes. Both use Google Lighthouse, the same engine that powers PageSpeed Insights. You'll see the same Core Web Vitals metrics (LCP, CLS, FCP, TBT) and performance scoring methodology.
It depends on your workflow. If you rely heavily on waterfall charts and filmstrip views for debugging, you'll want to keep GTmetrix for that. If your main need is monitoring performance across regions, Ahoj Metrics can replace GTmetrix for that use case.
Our audits test from multiple regions simultaneously using ephemeral cloud infrastructure. Each audit spins up workers in up to 18 global locations. The infrastructure cost per audit is higher, but you get a global view in a single test rather than running multiple individual tests.
GTmetrix lets you select a test location for each individual test. To test from 5 locations, you'd run 5 separate tests. Ahoj Metrics runs all regions in parallel as a single audit.
GTmetrix currently has more locations (22-25 depending on plan). Ahoj Metrics has 18 regions and is expanding. If you need a specific location that only GTmetrix covers, that's worth considering.
Yes. The Field Data feature lets you look up Chrome User Experience Report (CrUX) data for any domain — p75 values and Good/Needs Improvement/Poor distributions for all five Core Web Vitals (LCP, INP, CLS, FCP, TTFB). This is the same dataset Google uses in Search Console. GTmetrix doesn't offer CrUX data.
