rtx is a tool for managing programming language and tool versions. For example, use this to install a particular version of node.js and ruby for a project. Using rtx activate, you can have your shell automatically switch to the correct node and ruby versions when you cd into the project's directory1. Other projects on your machine can use a different set of versions. rtx is inspired by asdf and uses asdf's vast plugin ecosystem under the hood. However, it is much faster than asdf and has a more friendly user experience.
