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.
The Product Engineer
This is a single-snippet client-side product: AI-generated microexperiences with visitor-percentage control, a recommended 50/50 split ramping toward 95% personalised traffic, and a permanent 5% control group running in the background. We found no public information on SDKs for any language, server-side or edge delivery, or multivariate and multi-page tests, so a team that wants to run experiments behind its own feature flags and stack has nothing documented to build on. 3 4 5
