Ruler Analytics vs Causality Engine
Ruler Analytics is best for lead-gen businesses tracking calls and forms. 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 Ruler Analytics; use us as the causal second opinion.
Side by side. Every fact sourced.
Short answer: Keep Ruler 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 Ruler Analytics' cookie-based multi-touch attribution, 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 Ruler Analytics falls short
- Cookie-dependent tracking degrades with privacy changes
- Focused on lead-gen not ecommerce
- Complex CRM integration required
- No causal measurement methodology
What Causality Engine does differently
- No pixel and no tag. It reads the GA4 export you already have, where Ruler 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.
