Erlang is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs.
We provide different releases and apply security updates on a regular basis. Currently, these versions are available: 20, 21, 22, 23 and 24. All versions include Elixir and Mix, a build tool that allows you to easily create projects, manage tasks, run tests and more.
If you don’t select a certain version, our default will be used. We decided to default to version 21

Connection to webserver¶
In order to make your application accessable from the outside, you need to
connect it to the webserver, using a web backend. Please note
that your application must listen on the IP

between 1024 and 65535.
