We are starting to adopt devenv in our team. Overall it's really good--we have control over our toolchain, environment, and the processes that we start. There are some lingering papercuts though, like they haven't yet released a version where they allow specifying the Go toolchain version, and they seem to periodically re-download the Nix package archive. But I think they are improving fairly quickly.

Ultimately, we might still end up moving to straight Nix flakes, just not sure yet.

I'd be interested in anybody who has tried https://devenv.sh/ and https://www.jetify.com/devbox and chosen one over the other. Tried devbox which has been good, but not devenv.

I briefly tried devenv and I find it much easier to use than raw nix, but I also had issues with my nix install on macos (using both the official and the DS installer). It worked well on my linux machine.

Today though mise has so many other great features, I would still choose it over devenv or devbox.
