## What it is
Elchemy is a transpiler that lets you write Elixir code using Elm's statically-typed syntax, compiling to idiomatic, readable Elixir that runs on the BEAM. It combines Elm's type safety and inference with Elixir's ecosystem and tooling, including type-safe interop with Elixir/Erlang based on typespecs.

## Use cases
- write type-safe elixir code with elm syntax
- transpile elm-like code to elixir
- add static typing to a beam project
- call elixir functions from a typed language
- eliminate runtime errors in elixir codebases

## When to choose
- you want Elm's type safety while targeting the BEAM/Elixir ecosystem
- you prefer Elm syntax and type inference for writing Elixir
- you need type-safe interop with existing Elixir/Erlang code

## When to avoid
- you develop on Windows or rely on non-Unix tooling
- you need side effects or JSON decoders support
- you need an actively maintained compiler - the project has not seen releases since 2020
