Choose Supermetrics when your problem is wiring up ad-platform and analytics data into Sheets, Looker Studio, Power BI, or a warehouse for reporting. Stack Causality Engine on top when you've moved the data and now want a causal conclusion on it.
€99 once, excl. VAT. Keep Supermetrics; use us as the causal second opinion.
Same question, different answer. Often the opposite answer.
Short answer: Keep Supermetrics. 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 Supermetrics' data extraction and aggregation (no attribution), for €99.
Compatible with Causality Engine: Yes. It installs nothing on your site; the one condition is GA4.

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.
Supermetrics is the marketing-data connector category leader: 130+ connectors piping ad-platform and analytics data into Google Sheets, BI tools, warehouses, and dashboards. The Relay42 acquisition in mid-2025 pushed them further toward a 'marketing intelligence platform' positioning, with newer messaging around AI and incrementality (vendor-asserted, lightly documented in independent sources).
Functionally it's a pipeline. Pricing scales by data source and connector (from $44 a month billed annually on the vendor's pricing page at the time of writing, rising with sources and destinations). Some reviewers flag per-source pricing creep, slow support response, and ecommerce-connector rate limits.
Which one is the right call for your situation.
Choose Supermetrics when
your problem is wiring up ad-platform and analytics data into Sheets, Looker Studio, Power BI, or a warehouse for reporting. That's the connector category they own.
Stack Causality Engine on top when
you've moved the data and now want a causal conclusion on it. We don't compete with a pipeline; we sit downstream of one. Use Supermetrics for the connectors, run us on the GA4 export.
Take it to your CFO.
Not a Supermetrics replacement. Connectors are a different job. A €99 causal read on the data you're already collecting.
The questions buyers ask about us vs Supermetrics.
Is Causality Engine a Supermetrics alternative?

No. A direct GA4 CSV export is enough.
