Polar Analytics vs Causality Engine
Polar Analytics is best for DTC brands wanting unified BI + basic attribution. Choose Causality Engine when you need a defensible per-channel read before a budget decision, from the GA4 export you already have.
€99 once, excl. VAT. Keep Polar Analytics; use us as the causal second opinion.
Side by side. Every fact sourced.
Short answer: Keep Polar Analytics. Causality Engine is not a replacement for it: it installs nothing and reads the GA4 export you already have, so it adds a read of what each channel caused on top of Polar Analytics' deterministic multi-touch attribution on its first-party pixel, for €99.

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.

Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.
Where Polar Analytics falls short
- BI dashboard first, attribution second
- Deterministic MTA misses untracked journeys
- Attribution runs on its pixel, which does not track retroactively
- Attribution is not the core product
What Causality Engine does differently
- No pixel and no tag. It reads the GA4 export you already have, where Polar Analytics needs its own tracking on the store.
- What each channel caused, next to what last-click gave it, with a data-health score on every channel.
- The first number 1 to 2 minutes after the upload, on whatever GA4 history you export; 12 months or more reads best.
- €99 once, excl. VAT. Pro is €299 a month, billed monthly, cancel any time.
- Full refund within 30 days, no questions asked. You keep the read.
