We don't require any access to your data,
We don't charge more as your traffic grows.
How AssertionHub works
With our built-in recorder, you add your website and while you navigate it, the recording is automatically generated. The starting point is to identify the journey you want to test. Once recorded, AssertionHub can run it daily or on demand, tracking issues get caught before they go live, not when they're already affecting your data collection.
Along with built-in validations, you can create custom validations on every specific detail you want to test. Built-in example: duplicate GA4 event or missing value on your purchase event. Custom example: a custom dimension you created or a non-standard event.
Easily check your test results with all the information about the issues found. Set an email to receive alerts if any issue is detected and schedule a User Journey to run daily automatically.
Every plan includes a certain number of hours to resolve issues you spot through AssertionHub. Your purchase event is not firing? We can fix it for you or at least point you to the fix. You will not find this service anywhere else.
Why AssertionHub?
No coding knowledge needed.
Anyone on your team should be able to protect your ad-spend from tracking issues. So we built Assertionhub to run tests without writing a single line of code. From analysts to marketers, everyone can validate tracking from day one.
Predictable costs. No per-event pricing.
Verifying that your purchase event fires should not depend on your traffic volume. That is why we offer a generous free tier and flat-rate plans that grow with your team, not your event count.
No script to install. No browser extension.
With Assertionhub you don't need to install anything. It runs entirely in the cloud, with nothing added to your codebase and nothing that can interfere with your tracking setup or website performance. Works on any browser, any device.
No AI in the validations.
Testing should be deterministic. Run the same test 100 times and, without a fix, you get the same result every time. It also means our pricing will never fluctuate with AI token costs.
What sets Assertionhub apart
Built-in recorder
Add your website URL and navigate it directly inside Assertionhub. The User Journey recording is automatically generated and the events for your tests are detected for you. No browser extension, no selectors to write.
Global tests
Need to validate something on every event or a specific set? Create a global test once and it runs across all matching events automatically. No repeating the same test over and over.
Modular tests
With other tools you create the same test every time you need it. In Assertionhub you create it once and reuse it across multiple recordings or steps.
Facilitated test creation
Start from a detected event and all the metrics are already prefilled. No need to remember which metric to use. Or describe in plain language what you want to test and our AI creates the test for you.
