GA4 DebugView is one of the first tools most marketers and developers reach for when something looks off with their tracking. It's built right into Google Analytics 4, it's free, and it gives you a real-time event stream from your own browser. For checking whether a GA4 event fires at all, it's genuinely hard to beat.
But there's a gap between "the event fires in my browser in debug mode" and "conversions are being recorded correctly in production, across platforms, for real users." That gap is where things break — and where ConversionOK comes in.
At a glance

| Platforms supported | GA4 only | Google Ads, GA4, Meta Pixel, TikTok Pixel, and more |
| Setup required | Enable debug mode via browser extension or GTM debug | Enter your URL — no extensions, no debug flags |
| Consent state testing | Limited — you control your own consent banner manually | Tests what fires when consent is denied vs. granted |
| Value / currency check | Shows event parameters including value | Verifies value and currency reach the ad platform correctly |

Where GA4 DebugView shines
DebugView deserves credit for what it does well — and it does several things very well.
Free and built in
If you already have GA4 set up, DebugView is right there. No extra tools to install, no subscription, no setup beyond enabling debug mode. For teams watching their tool budget, that matters.
Real-time event stream with parameter inspection
DebugView shows every GA4 event as it fires, in order, with full parameter detail. You can click into any event and see every parameter — event name, value, currency, user properties, everything GA4 received. For diagnosing which parameters are missing or malformed, this level of detail is excellent.
See every GA4 event, not just conversions
DebugView doesn't just show conversion events. It shows page_view, scroll, click, and every custom event you've configured. When you're building out your GA4 implementation from scratch, this full picture is exactly what you need.
Where ConversionOK fills the gap
DebugView answers "does this event fire in my browser in debug mode?" ConversionOK answers a different question: "are conversions actually being recorded correctly in production?"
No self-clicking required
To test with DebugView, you need to navigate to your site and trigger the conversion yourself. If you're running paid campaigns, the natural instinct is to click your own ad to test the full flow. But clicking your own Google ads is against Google's policy — it counts as invalid traffic and can flag your account.
ConversionOK tests from an external browser. You never click your own ad. You never generate invalid traffic. The test simulates a real user journey without putting your ad account at risk.
Consent state testing
With privacy regulations tightening and Consent Mode v2 now required in the EU, a critical question is: what happens to your conversion tracking when a user denies consent?
DebugView shows you what fires in your browser, with your consent state. To test different consent scenarios, you'd need to manually clear cookies, change your consent choice, and repeat — and even then, you're only testing GA4.
ConversionOK lets you see what fires under different consent states, across multiple platforms, in a single test. You can verify that Google Ads still receives modeled conversions when consent is denied, and that Meta's Conversions API handles the fallback correctly.
Beyond GA4 — test every ad platform at once
DebugView only shows GA4 events. If you're also running Meta ads, TikTok campaigns, or other platforms, you need separate tools for each — Meta's Events Manager, TikTok's Events Manager, and so on.
ConversionOK shows you what fires across all your ad platforms in one place. When a conversion should trigger a GA4 event, a Google Ads conversion tag, and a Meta Pixel event simultaneously, you can verify all three at once. No switching between dashboards.
Production conditions, not debug mode
This is a subtle but important distinction. Debug mode can behave differently from production. Some tag configurations fire differently when GTM's preview mode is active. Some consent management platforms behave differently when they detect debug extensions. The point of verification is to confirm what real users experience — and real users aren't in debug mode.
ConversionOK tests under production conditions. What you see is what your actual visitors trigger.
Who should choose which
The honest answer: most teams should use both, for different purposes.
Use GA4 DebugView when:
- You're building or modifying your GA4 implementation
- You need to inspect individual event parameters in detail
- You're debugging why a specific GA4 event isn't firing
- You want a quick, free check during development
Use ConversionOK when:
- You need to verify conversions are working in production — not just in debug mode
- You want to verify your GA4 tag alongside Google Ads, Meta, and other platforms
- You need to test consent state scenarios without clicking your own ads
- You want to catch issues like duplicate conversions or missing value parameters before they affect your data
- You need ongoing verification that nothing has broken after a site update
Think of it this way: DebugView is your development tool. ConversionOK is your production verification tool. You wouldn't skip testing in production just because unit tests passed — the same logic applies to conversion tracking.
FAQ
Can I use GA4 DebugView without the Chrome extension?
Yes. You can enable debug mode by adding debug_mode: true to your GA4 configuration in GTM, or by using the debug_mode parameter in your gtag.js config. The Chrome extension (GA Debugger) is the most common method, but it's not the only one.
Does DebugView show Google Ads conversion data?
No. DebugView only shows GA4 events. Google Ads conversion tags (the ones placed via gtag.js or GTM's "Google Ads Conversion Tracking" tag) don't appear in DebugView. To verify those, you'd typically check the Google Ads interface — or use ConversionOK, which shows both GA4 and Google Ads conversion events.
Is debug mode data included in GA4 reports?
By default, events sent with debug_mode: true are still processed into your regular GA4 reports. They appear in DebugView and in your standard reports. If you want to exclude debug traffic from reports, you'll need to filter it manually. This means DebugView testing can add noise to your analytics data — another reason to keep debug testing to development and use external verification for production.
The bottom line
GA4 DebugView is a genuinely useful, free tool for GA4 development. It's the right choice when you're building your implementation and need to see every parameter on every event in real time.
But if your question is "are my conversions actually working correctly in production, across all my ad platforms, without me clicking my own ads?" — that's a different question, and it needs a different tool. ConversionOK tests from the outside, under real conditions, across every platform, so you can verify without guessing.
