AssertionHub is a no-code automated testing platform built for digital analysts and marketing teams who need to continuously validate their analytics and marketing tag implementations before broken data reaches their reports. You record user journeys once through the built-in browser recorder, then schedule them to run daily. At each step, AssertionHub validates that GA4, Meta Pixel, Google Ads, GTM Data Layer, Adobe Web SDK, Bing Ads, and other events fire correctly. No script installation, no access to your analytics accounts, no coding required. Key capabilities: - Built-in browser recorder: record your conversion funnels directly in the app, schedule them to run daily, and get Slack or email alerts when something breaks - AI-assisted test creation: click an event in the live panel during recording and let AI prefill the parameters for you - Built-in tests and duplicate event detection for GA4, Meta, GTM, and Google Ads, continuously updated - Google Consent Mode awareness: see which consent state each event fired under at the individual event level - Global checks: define a validation once and reuse it across all recordings and vendors - No installation on your website and no access to your analytics accounts needed.
