Revaboxy is a reverse proxy made for A/B testing of front end applications. It is placed in front of two or more versions of a frontend and does randomize the trafic to the different versions based on probability. When a users browser makes subsequent requests, revaboxy will automaticly select the same version as before.
Revaboxy is released as docker images, binaries for linux/windows/mac and as a Go library.
When setting up Revaboxy, every version has to be setup with the url and probability that it will be selected.
These environment variables are called VERSION_NAME_URL and VERSION_NAME_PROBABILITY.
As an example, say we have two version, one called DEFAULT and one called GREEN_BACKGROUND. The environment variables needed would be:
VERSION_DEFAULT_URL=http://defaulturl
VERSION_DEFAULT_PROBABILITY=0.6
VERSION_GREEN_BACKGROUND_URL=http://greenbackgroundurl
VERSION_GREEN_BACKGROUND_PROBABILITY=0.4| Name | Default | Description |
