Caramel is a functional programming language that compiles OCaml-style source code to run on the Erlang VM (BEAM), combining OCaml's type system with Erlang's fault-tolerant concurrency. It ships as a single executable with a built-in formatter and type-safe interop with existing Erlang and Elixir code.
Use cases
- write type-safe Erlang applications
- compile OCaml to the Erlang VM
- add static typing to an Elixir or Erlang codebase
- build fault-tolerant distributed systems with a functional language
- format BEAM language source code
- interop between OCaml and Erlang code
When to choose
- you want OCaml-style type safety and inference while targeting the BEAM ecosystem
- you need zero-cost interop with existing Erlang or Elixir code
- you want a batteries-included single-binary toolchain with a formatter
When to avoid
- you need a mature, actively developed language — development has slowed since 2023
- you want a large ecosystem and community, where Elixir, Gleam, or Erlang are safer bets
- you need Reason syntax support, which was never fully delivered
