Perti

Perti is Wix’s holistic experiment system, it covers the lifecycle of product experimenting including A/B tests and feature toggles. Petri is used at large scale at Wix, supporting dozens of daily changes (instantly affecting production, no deployment needed).

Main features include create and gradually open A/B tests to affect your user’s experience. This feature helps our Product Managers collect data on user behavior before making decisions. Create Feature Toggles to control inner implementation details. This feature helps our developers gradually roll out features.

Define filters to determine what users will be included in your defined experiments. Our filters include language, geo, user-agent, individual user IDs (usually used for QA) and more. Custom filters can also be added. Conduction values are periodically reported back to the server to enable quick triaging as well as automatic pausing if a limit to the number of users is specified.
