Client A/B testing refers to the method of performing experimentation related changes to a web application at runtime, typically within a browser. This method of experimentation is popular in the industry as it is easier to deploy, requires minimal to no engineering bandwidth for creating experiments and is accessible to non-engineering personnel as well.
This incubation's objective is to devise methods of conducting the same outcome with all its benefits offered, but without the performance penalties.
- Standardize A/B transformation operations to a spec.
- Enable application of experimentation changes at the Origin, an intermediary CDN/Edge/Proxy or the Browser.
- Minimize or eliminate performance metrics degradation caused by application of changes in the browser through performant methods and through exploration of browser-native implementations.
- Explainer and supported operations
