Causality Engine installs nothing on your site. It reads the GA4 export you already have, so it runs on top of any tool here without touching its setup. The one condition: GA4 runs on your store too. “Not stated” means we could not find it on the vendor's own pages or listings on 12 October 2026; it does not mean the feature is missing.

Where Northbeam Shines
Northbeam has earned its place in the market by offering a sophisticated multi-touch attribution platform. It provides a unified view of marketing data, which is a significant step up from relying on the fragmented reporting of individual ad platforms. Its key strengths lie in its complete feature set, including detailed customer journey mapping, creative analytics, and a wide array of integrations. Furthermore, Northbeam's introduction of 'Clicks + Deterministic Views' demonstrates a commitment to moving beyond last-click attribution and capturing a more complete picture of ad performance. For businesses seeking to consolidate their marketing data and gain a deeper understanding of customer touchpoints, Northbeam offers a useful and reliable solution.
Correlation is Not Causation: The Billion-Dollar Mistake
Northbeam, and the entire category of attribution tools, are built on a foundation of correlation. They are exceptionally good at telling you what happened. A user saw a TikTok ad, then a Facebook ad, then searched on Google, and then purchased. The system logs these touchpoints and distributes credit. The fundamental flaw is that it never answers why the purchase happened. It assumes every touchpoint played a role, but it cannot distinguish between a touchpoint that influenced the decision and one that was merely present in the journey.
Causality Engine uses causal inference on the GA4 history you already have to estimate what each channel caused.
Feature Comparison: A Tale of Two Philosophies
When to Choose Northbeam vs. Causality Engine
Northbeam is an excellent choice for businesses that have a complex marketing ecosystem with numerous channels and require a unified view of all touchpoints. If your primary goal is to track and visualize every interaction a customer has with your brand, Northbeam provides a useful and complete solution.
Causality Engine reads one file, the Attribution paths export from GA4, and shows what each channel caused next to what last-click gave it. The read works on GA4 channel groups, not campaigns or creatives, and it is a one-off read rather than a daily dashboard. We are not a better attribution tool; we are a different category of tool altogether.
