About Erlang/OTP

Erlang is a functional programming language built around lightweight processes that communicate by sending messages. OTP is the runtime and set of libraries and design principles that ship with it, used for systems that must keep running when parts fail.

The distribution includes the BEAM virtual machine, the standard library and an interactive shell for trying code as you write it. Release 29 is the current version. Erlang/OTP also underpins other BEAM languages, so it is a common install for anyone working with that ecosystem.

Strengths

  • Lightweight processes and message passing built into the language
  • OTP design principles for supervised, fault-tolerant applications
  • Interactive shell for quick experiments
  • Mature runtime shared by other BEAM languages

Limitations

  • Functional style and syntax take time to learn for newcomers
  • Better suited to servers and distributed systems than desktop apps

Alternatives to Erlang/OTP

Compare all

Software that can replace Erlang/OTP for an important use case, and what changes if you switch.

  • Elixir

    A dynamic, functional programming language that runs on the Erlang VM for scalable, maintainable applications.

    FreeOpen sourceWindowsmacOSLinuxCommand line

    Elixir runs on the same Erlang VM with a different syntax, a gradual type system and ecosystem tools such as Phoenix and Ecto.

  • Gleam

    A type-safe functional programming language that runs on the Erlang VM and JavaScript runtimes.

    FreeOpen sourceWindowsmacOSLinuxCommand line

    Gleam adds static types on the Erlang VM and can also target JavaScript, but has a younger, smaller community than Erlang.
