What is it?

Gleam is a statically typed programming language whose compiler is written in Rust. It targets the Erlang virtual machine, so programs can use the BEAM runtime's concurrency and fault-tolerance model while getting type checking at compile time.

The project is aimed at developers who want type safety for backend and distributed systems without leaving the Erlang ecosystem. Its compiler and tooling are developed as a single project hosted on GitHub, and the language is positioned as a friendly alternative for building scalable services.

The repository's README is brief and mainly points to the project website for documentation, sponsorship information, and community links.

Key features
