About:
Ry is a command-line tool for managing multiple Ruby versions and environments on a per-project basis. It functions similarly to Python's virtualenv, allowing users to switch between different Ruby interpreters and sets of gems seamlessly. This tool simplifies dependency management by isolating project-specific environments without the overhead of heavier version managers.

Key Features:

Per-project Ruby version switching
Automatic environment activation via .ruby-version files
Lightweight and fast operation
Seamless integration with existing Ruby workflows

Use Cases:

Managing legacy applications that require older Ruby versions alongside modern projects
Isolating gem dependencies between different development projects
Simplifying onboarding for developers by automatically using the correct Ruby version

Alternatives:

rbenv – rbenv is more widely used and feature-rich, but ry offers a simpler, more lightweight approach focused on per-project environments.
RVM – RVM is a more comprehensive tool that also manages gemsets, but ry is significantly lighter and less intrusive.
asdf – asdf is a multi-language version manager, whereas ry is specialized solely for Ruby environments.
