Triple Whale vs Cometly
Triple Whale is best for Shopify brands at scale wanting a unified dashboard. Cometly is best for B2B SaaS teams (Stripe- and CRM-native), not primarily ecommerce. If what you need is what each channel caused, there is a third option: a causal read of the GA4 export you already have.
€99 once, excl. VAT. Keep either one; use us as the causal second opinion.
Side by side. Every fact sourced.
Short answer: Triple Whale uses pixel-based multi-touch attribution and Cometly uses first-party pixel + server-side tracking. Causality Engine is compatible with all of them: it installs nothing and reads the GA4 export you already have, so it adds a read of what each channel caused on top of whichever you keep, 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 Triple Whale falls short
- Pixel-dependent: needs its tracking script on every store page, and browser privacy controls limit what a pixel can observe
- Multi-touch attribution starts on the paid Foundation plan ($219/mo); the free plan has first- and last-click models
- Correlation not causation
- Multi-touch attribution allocates credit across observed touchpoints; it is not a counterfactual estimate of what a channel caused
Where Cometly falls short
- Requires the Comet Pixel plus server-side setup
- No free trial, vendor cites required CRM and ad-platform setup
- Pixel, webhook and click-ID setup required per store
- Multi-touch tracking, not causal measurement
