Why Agencies Switch to isMyWebOk

No More Manual Testing

With GTmetrix, you often have to log in and trigger a test to see the current state. Across 20+ clients, that takes hours of your time.

With isMyWebOk: Add a site once. We check it every morning. You only get reports and alerts.

History That Doesn't Expire

Free and lower-tier GTmetrix plans often delete report history after a week or months. It's hard to prove annual progress to a client.

With isMyWebOk: We keep your result history forever. Show your client "Before" and "After" charts from a year ago.

Client-Friendly Language

GTmetrix reports are amazing for devs, but scary for business owners. Too many Waterfalls and technical jargon.

With isMyWebOk: We translate tech to business impact. "Your site is fast" vs "LCP 2.4s (render blocking resources...)".

The Hybrid Approach

Many of our customers still use the free version of GTmetrix! How?

The Perfect Workflow:

isMyWebOk monitors 50 client sites daily in the background.
You get an alert: "Client X's site slowed down".
You visit GTmetrix (Free), run a deep test to find the cause.

Don't overpay for continuous monitoring in GTmetrix if you only need it for occasional diagnostics.

When is GTmetrix Better?

Let's be honest - GTmetrix is legendary for a reason.

🔧 Choose GTmetrix if:

You are a developer fixing a specific bug.
You need a Waterfall chart (resource loading).
You need to test from very specific global locations.

🛡️ Choose isMyWebOk if:

You manage multiple sites (Maintenance).
You want to know about downtime before your client.
You need reports that clients understand.

Frequently Asked Questions

Will isMyWebOk results be the same as GTmetrix?

Close, but not identical. Both tools use Google Lighthouse technology. GTmetrix might test from a different location or device. The trends, however, will match - if your site slows down, both will catch it.

Does isMyWebOk replace GTmetrix?

It replaces paid GTmetrix plans for monitoring (alerting) purposes. It does not replace GTmetrix as a deep-dive developer analysis tool (debugging).
