Causality Engine vs Rockerbox: at a glance
Short answer: Keep Rockerbox. 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 Rockerbox's multi-touch attribution, MMM and control-group incrementality testing, 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.

Causality Engine: Causal Inference
Causality Engine, based in the Netherlands, reads the history you already have instead of running a test: causal inference on a GA4 export. That's causal attribution without an experiment, so the read grades itself with a data-health score on every channel.
How It Works: A Technical Overview
For each GA4 channel group (not each campaign or customer journey), the model estimates what the channel caused and sets last-click from the same export beside it: within 25% the two agree, and under 1% on both is too small to act on. The read arrives 1–2 minutes after upload; ad-platform connections are on the roadmap, not live.
| Feature | Rockerbox | Causality Engine |
|---|---|---|
| Methodology | Multi-touch attribution, MMM and control-group incrementality tests | causal inference on a GA4 export |
| Measures | Credit across tracked touchpoints; lift in designed experiments | What each channel caused, next to last-click |
| Experiments | Control-group tests; spend held back or shifted while they run | None to design; reads the history you already have |
| Pricing Model | Enterprise, quoted via sales; not publicly listed | €99 per read, or Pro at €299/mo |
Key Differentiators
What each channel caused: its share of the credit once Direct is split back to the channels that sent those buyers.
A data-health score on every channel: 0 to 100, grading the read rather than the channel; under 90, move budget in steps.
A next step per channel: raise, cut or hold, or fix tagging first, with how to test a channel in one region before you move budget.
Paths to purchase and receipts for every number come with each read; prices are on the pricing page.
Making the Switch
You don't have to switch anything to compare. Every platform grades its own homework, so start with two free checks: put last week's Meta- and Google-reported purchases next to your Shopify orders for the same week to see how far the platform numbers run ahead, then cut one channel's spend in one region for two weeks and compare revenue with the regions you left alone.

Frequently asked questions
Is Causality Engine a direct replacement for Rockerbox?
For a self-serve read of what each channel caused on a GA4 ecommerce brand, it can stand in for Rockerbox's attribution. Causality Engine works on GA4's channel groups and runs no experiments of its own.How long does it take to see results?
The first read arrives 1–2 minutes after you upload a GA4 export, and covers whatever GA4 history you export. Pro keeps the read updating as new GA4 data comes in.What is the main difference between causal inference and traditional attribution?
Traditional attribution splits the credit for a sale across tracked touchpoints by a rule or a model; causal inference estimates what would have happened without a channel. Causality Engine estimates what each channel caused from the GA4 history you already have, with no experiment to design.

- Causal AttributionCausal Attribution uses causal inference to determine which marketing touchpoints genuinely cause conversions, not just correlate with them.
- Causal InferenceCausal inference is the set of methods for estimating how much an outcome changes because of a cause, rather than alongside it. It works by comparing what happened with an estimate of what would have happened without the cause.
- Customer journeyCustomer journey is the path and sequence of interactions customers have with a website. Customers use multiple devices and channels, making a consistent experience important.
- First Click AttributionFirst Click Attribution assigns all conversion credit to the first marketing touchpoint. Causal inference evaluates if first touchpoints truly drive conversions or if other interactions have greater causal impact.
- IncrementalityIncrementality is the part of an outcome, such as orders or revenue, that a marketing activity caused: the extra results compared with what would have happened without it. It is a causal effect, not the number of conversions credited to a channel.
- Last Click AttributionLast Click Attribution: Assigns all credit for a conversion to the final marketing touchpoint before that conversion.
- Linear AttributionLinear Attribution assigns equal credit to every marketing touchpoint in a customer's conversion path. This model distributes value uniformly across all interactions.
- Multi-Touch AttributionMulti-Touch Attribution assigns credit to multiple marketing touchpoints across the customer journey. It provides a complete view of channel impact on conversions.
