The QTE, Cloud Services, and Release Engineering team (collectively known as DevEx, Developer Experience) are kicking off a new project to create an advanced prototype of an on-demand test environment provisioner called Catalyst. This tool is a logical successor to Patch Demo, which could deploy MediaWikis for testing but not services, and DUCT, which could deploy Mediawikis and services for testing in Wikifunctions, but was not scalable to other teams/projects.

We expect the MVP (minimum viable prototype) to be ready in approximately two months and would be very interested in input/help from the community, both with the prototype and with where a generally available product might look like thereafter. More information on the project, its technology stack, and how to get involved is at https://wikitech.wikimedia.org/wiki/Catalyst.
