plenv review
A focused, free Perl manager with project pinning, shims, and plugin support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
plenv is a free, open-source command-line manager for developers who need to install and run multiple Perl versions. It supports global, project-local, and shell-specific selection, making it suitable for Perl teams that maintain projects with different runtime requirements. A project-local version is recorded in a .perl-version file, while shims route Perl executables to the selected version. Shell autocompletion is available for Bash and Zsh.
The product’s main strength is its focused version-selection model. Developers can install Perl versions through the perl-build plugin, rebuild shims after adding runtimes or commands, and migrate modules between Perl environments. This gives teams separate controls for a default runtime, a project runtime, and a temporary shell choice. The scope is intentionally narrow: plenv manages Perl rather than providing a shared version-management workflow across several programming languages. Teams seeking one manager for multiple language ecosystems should consider a different category fit.
plenv also fits Perl workflows through integrations with Carton, perl-build, and plenv-contrib. Its free, open-source distribution removes plan or tier decisions, while the macOS and Linux focus suits Unix-like development environments. The practical trade-off is that the workflow centers on command-line configuration, shims, shell integration, and project files rather than a graphical interface. Perl teams that want explicit control over runtime selection and module environments should pick plenv; teams needing broader language coverage or a GUI-oriented workflow should look elsewhere.

- perl-build, Carton, completions, and module migration support
- Where it doesn't
- Focused on Perl rather than multi-language version management
- Command-line workflow may require shell configuration knowledge
- Supports macOS and Linux development environments
