In their own words
frum
frum is a free Ruby version manager written in Rust. It can install and uninstall Ruby versions, list available or installed versions, and select a global or local version. It also works with .ruby-version files, so projects can specify which Ruby version frum should use. The project describes its implementation as pure Rust and says it does not use ruby-build. Installation methods listed include Homebrew or Linuxbrew, Arch Linux packages, Cargo, and release binaries. The README provides setup instructions for Bash, Zsh, and Fish and lists shell auto-completion. Ruby installation accepts configuration options such as an OpenSSL directory and jemalloc allocator selection. The README reports a benchmark in which evaluating frum init ran about six times faster than evaluating rbenv init. The project is MIT licensed and welcomes contributions, issues, and pull requests. Linux and macOS are listed as supported platforms; Windows is mentioned in the project’s goals. Its latest listed release is v0.1.2.
