I'm building a Starlark-based build system that operates at the level of building multi-container environments, rather than normal code assets: https://github.com/kurtosis-tech/kurtosis

It's kind of like Docker in the sense that it packages up an application in a reproducible, composable, and portable way...but instead of working at the level of one server, it works at the level of multi-server applications.

In the back of my head I'm very curious about making an application that just messages me on WhatsApp whenever its the birthday of one of my close friends because I never remember those
