Beamer is a tool that allows you to install and manage multiple versions of OTPless Erlang on the same machine.
curl -o- https://raw.githubusercontent.com/otpless-erlang/beamer/v0.0.1/install.sh | bash
beamer install x.y.z
beamer use x.y.z
beam -v
Inspired by NVM, Beamer is designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: Linux, macOS, and Windows WSL.
