About Gleam
Gleam combines a static type system and functional programming with the concurrent, fault-tolerant Erlang runtime, using a familiar modern syntax. Programs can use actor-based concurrency with lightweight processes and can also compile to JavaScript.
The compiler, build tool, formatter, package manager and editor integrations come in one install, so a new project starts with gleam new. Gleam code can use packages from the wider BEAM ecosystem.
Strengths
- Static types on the Erlang VM
- Compiler, build tool, formatter and package manager in one
- Can target JavaScript as well as Erlang
- Access to the BEAM package ecosystem
Limitations
- Younger language with a smaller community than Erlang or Elixir

Alternatives to Gleam
Compare allSoftware that can replace Gleam 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.
Elixir also runs on the Erlang VM but is dynamic with a gradual type system, has an established ecosystem including Phoenix and Ecto, and does not target JavaScript.
Erlang/OTP
The Erlang programming language and OTP runtime for building concurrent, fault-tolerant distributed systems.
Erlang/OTP is the original BEAM language with OTP supervision principles, dynamically typed and without Gleam's JavaScript target.
OCaml
A functional programming language with a strong static type system and a native-code compiler.
OCaml offers a strong static type system with a native-code compiler instead of targeting the Erlang VM or JavaScript.
