Have you looked into devcontainers? Could be a good option.

We use tilt right now for running the apps themselves. Haven’t delved into virtualized dev environments yet. We’re a Mac shop so we just have a list of brew commands to run. And for some critical tools they are invoked through docker so no cli install needed.

We have a file that houses the version and everything is done through a Makefile. So on the next main pull people will always invoke the correct version of a build tool.

I switch between Solarized light and solarized dark.
