rbenv is a version manager for the Ruby programming language on Unix-like systems, letting you switch between multiple Ruby versions per project via a .ruby-version file. Its companion ruby-build installs Ruby versions, and behavior is extensible through bash plugins.

Use cases

• manage multiple ruby versions on one machine
• pin a ruby version per project
• install specific ruby versions with ruby-build
• switch ruby versions when changing directories
• set up a consistent ruby environment for a team

When to choose

• you work on multiple Ruby projects needing different Ruby versions
• you want a lightweight, shell-based version manager without extra runtime overhead
• you need per-project version pinning via .ruby-version

When to avoid

• you need a single system-wide Ruby only
• you want a version manager that also handles gems isolation out of the box (consider bundler or alternatives like asdf)
• you are on Windows without WSL
