For mise alternatives, take one project with multiple runtime versions and set it up on a clean machine.
- Pin runtimes and tools in version-controlled configuration.
- Install from scratch and verify exact versions and checksums where available.
- Run project tasks and environment-variable loading as currently used.
- Test switching between two projects without version leakage.
- Compare Windows, macOS, Linux, and CI behavior if the team spans them.
A version manager is valuable when onboarding and CI match local development. Measure setup repeatability, not just command syntax.
