Read this page as one judge. Each weighs the same scores by what they care about.

The CRO Consultant

Weighted verdict

Sets up testing programmes for several clients and has to recommend a platform each can afford and defend. Reads for multi-project management, clean analytics integration, a consent setup a client's DPO will sign off, and a traffic metric she can estimate before the contract.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The CRO Consultant

Experiment types & delivery

How this is scored

What can be tested and where: client-side changes through an editor, server-side and feature experiments through SDKs, multivariate and multi-page tests, and personalisation — judged on what the documentation shows rather than on the feature grid.

0 — Simple A/B split of one page element through a visual editor; no server-side option, no targeting beyond URL.

3 — Client-side A/B and split-URL tests with basic audience targeting, and no SDK or server-side delivery.

5 — Client-side and server-side experiments through documented SDKs for common languages, multivariate and multi-page tests, audience targeting on behaviour and attributes, and rule-based personalisation.

8 — Feature-flag-based experiments sharing one audience and metric model with web tests, mutually exclusive experiment groups, holdouts, edge or CDN delivery, and personalisation that can itself be tested against a control.

10 — One experimentation programme across every surface: web, app, server and edge from the same platform, experiment interactions managed, a documented experiment lifecycle from hypothesis to archived result, and a library of past results a team can search.

Report an error

The CRO Consultant

The homepage positions a server-side programme across native apps, websites, email and CRM, and algorithms with multiple SDKs and a searchable experiment hub for documentation and decisions, which is broader than client-side-only tools. But the SDKs are marketing copy rather than documentation, and we found no public information on multivariate or multi-page tests, audience targeting, personalisation, or feature-flag mechanics such as holdouts and mutual exclusion, so I cannot tell a client which test types the platform actually supports. 1 3

Statistical method & guardrails

How this is scored

Which statistics decide the winner and what protects the customer from misreading them. Scored on what the vendor documents: the method by name, how peeking and multiple comparisons are handled, and whether sample ratio mismatch is detected.

0 — A "winner" or "probability to beat" figure with no documented method, no stated sample-size guidance and no warning against stopping early.

3 — The method is named (frequentist or Bayesian) but its assumptions are not documented, and nothing prevents a test from being called while it is still underpowered.

5 — Documented method with confidence or credible intervals, a sample-size or test-duration calculator, and stated guidance on when a result may be read.

8 — Sequential testing or an equivalent documented protection against peeking, correction for multiple metrics or variants, sample ratio mismatch detection, variance reduction such as CUPED, and guardrail metrics that can stop a harmful test.

10 — The statistics are auditable: methodology published in enough detail to reproduce a result, the choice of method explained per use case, raw per-visitor data available for independent re-analysis, and the interface refuses to present an underpowered result as a conclusion.

Report an error

The CRO Consultant

Group Sequential Testing is named in the published feature list, which is a method built for repeated looks at live results, but its assumptions are not documented and we found no public information on sample-size guidance, multiple-comparison correction, or sample ratio mismatch detection. A named method with no visible methodology is exactly what I would struggle to defend to a data-minded client. 3

Snippet performance & flicker

How this is scored

The cost the client-side snippet imposes on the page it tests: blocking load, flicker of original content, script weight and the effect on Core Web Vitals — scored on what the vendor measures and publishes, not on "lightning fast".

0 — A synchronous snippet with no stated size, no flicker handling and no mention of performance.

3 — An anti-flicker snippet that hides the page until the test loads, with a timeout, and no published figures for script size or load cost.

5 — Script size and loading behaviour documented, asynchronous loading option, flicker handling explained with its trade-off, and CDN delivery of the snippet.

8 — Published performance figures including impact on Core Web Vitals, a self-hosting or first-party-domain option for the script, per-project bundles containing only active experiments, and a server-side or edge alternative for flicker-sensitive tests.

10 — Performance is a stated commitment: measured overhead published and maintained, flicker eliminated by edge or server-side rendering as a documented path, and tooling that shows the customer what their own configuration costs the page.

Report an error

The CRO Consultant

"Keep your vitals performant" is positioning, not measurement, and we found no published figures for script size, loading behaviour, flicker handling or Core Web Vitals impact. The server-side, build-on-your-own-stack story implies a light client footprint, but nothing on the captured pages quantifies it, so I cannot set a client's expectation of page cost. 1 3

Analytics, data export & integrations

How this is scored

Getting results and raw data out: integration with analytics and tag management, export of visitor-level results, warehouse-native analysis, and an API — because an experiment result that cannot be checked in the customer's own data is a claim, not a finding.

0 — Results visible in the vendor's dashboard only; no export, no analytics integration, no API.

3 — CSV export of aggregated results and one analytics integration, with no visitor-level data and no documented API.

5 — Integrations with common analytics and tag managers, export of results, and a documented API for managing experiments and reading results.

8 — Visitor-level raw data export or streaming to a data warehouse, warehouse-native analysis on the customer's own metrics, CDP integration for audiences, and an API with stated limits.

10 — The platform treats the customer's warehouse as the source of truth: metrics defined once and computed there, full historical experiment data exportable in open formats, and a versioned API a team can build its own programme tooling on.

Report an error

The CRO Consultant

Multiple SDKs, user-crafted metrics, real-time data and one-click programme reporting are claimed on the homepage, but the SDKs are not documented with languages, and we found no public information on an API, export of visitor-level results, or named analytics, tag manager or warehouse integrations. An experiment result I cannot check against a client's own data is a claim rather than a finding, so this gap weighs heavily in any recommendation I would make. 1

European sovereignty

How this is scored

Where visitor data is processed and stored and who the contracting entity is. Independently sourced by the sovereignty pipeline; weighted higher here than in categories that hold only the customer's own data, because the script runs on every visitor to the customer's site and their behaviour is what the platform records.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and visitor data leaving the EU without a stated safeguard.

3 — EU data residency offered as an option or an enterprise add-on while the contracting entity is non-EU, or the subprocessor list is absent.

5 — EU processing of visitor data as standard and an EU contracting entity, but parts of the chain — CDN, support access, analytics — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure including the delivery of the snippet, EU contracting entity, subprocessor list published, and a DPA covering the visitor data the script collects.

10 — Sovereign end to end and evidenced: vendor, entity, hosting, snippet delivery and every subprocessor European, certification published, and no visitor data reaching a non-EU party at any point.

Report an error

The CRO Consultant

The contracting entity is ABsmartly B.V. of Amsterdam, which is what I want to see, but the captured privacy policy states collected data may be stored on servers in the USA, with standard contractual clauses cited as the safeguard, and the contents of the linked subprocessors page are not captured. Visitor-data residency is therefore not confirmed, and US storage is not something I can hand a European client's DPO unchallenged. 1 2

Pricing transparency not rated — the vendor publishes no price

How this is scored

A category priced by traffic — monthly tracked users, visitors or impressions — where the tier a site lands in depends on numbers the buyer has to estimate. Whether a buyer can compute the real annual cost including traffic limits, overage, server-side or personalisation modules and seats — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A starting price or a free tier exists, but the traffic metric, the limits and what happens above them are unstated — the invoice is unknowable.

5 — Tier prices public with the traffic metric and its limits defined, but at least one commonly needed piece (server-side SDKs, personalisation, overage) is unpriced or "contact sales".

8 — Every tier priced publicly with the traffic metric defined, limits, overage rates, module prices, minimum term and VAT treatment stated.

10 — Complete price computability: annual invoice derivable for a given traffic volume, set of modules and team size, with overage and every add-on published.

Report an error

The CRO Consultant

The only path to a price is a demo request form, and we found no public information on tiers, the traffic metric, or what happens above the limits — so there is no way to estimate a client's annual invoice before the contract. The terms at least give a 14-working-day cooling-off period with a refund within 30 days of a written cancellation letter, but after that the subscription is "100% non-refundable" and prices can be changed "at any time". 1 3
