About:
Proto is a pluggable version manager for multiple programming languages, similar to asdf but with modern tooling and better performance. It allows developers to install and switch between different versions of languages, CLIs, and tools on a per-project or global basis. The tool is built in Rust and supports a wide ecosystem of plugins.
Key Features:
  • Multi-language support via plugins (Node.js, Python, Rust, Go, etc.)
  • Fast, Rust-based implementation for improved performance
  • Declarative configuration in a single proto.toml file
  • Automatic version detection and switching per project
Use Cases:
  • Managing disparate language versions across multiple projects on a single machine
  • Ensuring consistent tooling versions for development teams
Alternatives:
  • asdf – Proto is a modern, faster alternative with a more ergonomic configuration format and improved plugin system.
  • nvm – NVM is Node.js specific, whereas Proto manages multiple languages and tools with a single CLI.
