Talk:A/B testing

What software is used for A/B testing at Wikipedia?

What software is used for A/B testing at Wikipedia? Doesn't appear to be mentioned on this page. For example, they're conducting an A/B tests on enwiki for the skin for vector-2022 right now. What software is being used? Are there Puppet config files for it? How would one pull up a list of active A/B tests? How would one create a new A/B test? Novem Linguae (talk) 03:16, 9 June 2023 (UTC)
