Gleam Has a Free Type-Safe Language That Runs on the BEAM — Erlang's Power, Modern Syntax
The BEAM Problem Erlang powers WhatsApp (2 billion users, 50 engineers). Elixir made it beautiful. But both have a secret weakness: no static types. Your Elixir app works great — until production reveals a type mismatch that the compiler never caught. Gleam fixes this. Full static types. Runs on the BEAM. Zero runtime overhead. What Gleam Gives You Type-Safe Erlang/Elixir Interop import gleam/io import gleam/int pub fn main() { let answer = add(20, 22) io.println("The answer is: " <> int.to_string(answer)) } fn add(a: Int, b: Int) -> Int { a + b } Every function has types. The compiler catches mistakes before runtime. Pattern Matching pub type Shape { Circle(radius: Float) Rectangle(width: Float, height: Float) } pub fn area(shape: Shape) -> Float { case shape { Circle(r) -> 3.14159 *. r *. r Rectangle(w, h) -> w *. h } } Forget a case? Compiler error. Not a runtime crash at 3 AM. Use All of Erlang's Libraries // Call Erlang's crypto module directly @external(erlang, "crypto", "strong_
