Conda does not solve the problems of deployment and they don't have any reproducibility guarantees. That's not surprising considering how Conda binaries are built.

That's why I emphasized Pixi. With Pixi you get a per-platform lockfile that guarantees installation of the exact versions.

If what you want is to deploy a server or development environment, you already get it with Pixi. If you want a Windows installer with DLLs, you don't get. However it was never the reason.
