Glew and Causality Engine, fact by fact
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.
How to switch, in five steps.
No cancellation required yet
Keep Glew running (its terms: annual prepayment (Glew Pro); custom pricing (Glew Plus)). Causality Engine reads your GA4 CSV export, so nothing conflicts and no data moves between the two.
Upload your GA4 CSV (no integration required)
Export 12 months or more of GA4 data and upload it. Longer reads better. No OAuth, no pixel, no code, no DNS changes. Shopify native is on the roadmap.
Run your first analysis
What each channel caused, next to last-click, with a data-health score on each, 1 to 2 minutes after the upload. Compare it with what Glew was telling you.
Evaluate side by side
Run both for a month and compare them channel by channel. Where they disagree is where a budget decision is at stake.
Cancel Glew when ready
Only if the side-by-side says you should. On refunds, Glew states: no refunds; annual term with no early termination. Nothing in Causality Engine depends on Glew being gone.
What to weigh before you leave Glew
Glew uses BI dashboarding + reporting and is best for ecommerce brands wanting operational BI dashboards. Where it differs from a causal read:
- BI dashboards, no marketing attribution
- Built for store reporting, not for estimating incremental channel contribution
- No causal or incrementality methods
- Operational analytics not marketing measurement

Yes. 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.
