About Gleam

Key Features of Gleam



Gleam's powerful static type system helps find and prevent bugs at compile time.

Fault tolerant

The Erlang virtual machine provides well tested mechanisms for gracefully handling failure.

Friendly compiler

Hunting down bugs can be stressful so Gleam's compiler provides clear and helpful feedback.

Friendly community

People of all backgrounds, genders, and experience levels are welcome in the Gleam community.

Erlang compatible

Gleam makes it easy to use code written in other BEAM languages such as Erlang, Elixir and LFE.


Gleam adds no overhead of its own, so all Gleam programs are as fast as their Erlang counterparts.

Get mentored the Gleam way

Every language has its own way of doing things. Gleam is no different. Our mentors will help you learn to think like a Gleam developer and how to write idiomatic code in Gleam. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Gleam - they'll help you discover the things you don't know that you don't know.
