Ask HN: What SDK/Version manager do you use?

What's your preferred setup for isolating SDKs and dependencies across different projects (Go, Python, Node, etc.) on macOS without using containers? I'm struggling with global pollution (e.g., GOPATH, site-packages) and want a project-local approach that plays nicely with JetBrains IDEs. What tools/techniques do you find most effective: asdf, mise, direnv, language-specific managers (nvm, pyenv), or something else entirely? What are the trade-offs?
