Track every click. Or measure what caused the sale.
Choose Hyros when you run long, multi-touch funnels or high-ticket offers with phone sales, and your core problem is tracking a winding click-to-revenue path that platforms miss. Choose Causality Engine when you're a Shopify and GA4 ecommerce brand and the question is which spend is actually incremental, not where did every click go.
€99 once, excl. VAT. Keep Hyros; use us as the causal second opinion.

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.
Every fact, sourced. And why you can keep Hyros.
Short answer: Keep Hyros. 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 Hyros' server-side click tracking, 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.

The short version. What each one is for.
Hyros is built for a specific world: long, multi-step funnels (coaching, info-products, high-ticket and long-sales-cycle advertisers) where deterministic click-to-revenue tracking and call tracking are the hard part. For that use case it's strong, and it's often credited with recovering conversions Meta and Google under-report.
For a Shopify DTC brand, though, it's a different animal. Hyros is among the heaviest installs on this list: watcher scripts on every landing and conversion page, platform API connections, and reported 2 to 12 week (occasionally longer) implementations with real technical hours. And it's still click-tracking, not causal: more precise credit, not incrementality. Pricing is one plan sized to the revenue it tracks: its page publishes no figure and quotes the price on a setup call (read 2026-10-12).
Which one is the right call for your situation.
Choose Hyros when
you run long, multi-touch funnels or high-ticket offers with phone sales, and your core problem is tracking a winding click-to-revenue path that platforms miss. That's its home turf.
Choose Causality Engine when
you're a Shopify and GA4 ecommerce brand and the question is which spend is actually incremental, not where did every click go. No watcher scripts, no multi-week install, no developer ticket. A causal read on your existing data in minutes for €99.
Take it to your CFO.
Zero engineering hours and no scripts in production, versus a multi-week tracking install. And a €99 credit-card read versus a subscription that scales with tracked revenue.
