Firefly is an alternative implementation of the BEAM virtual machine, including a compiler and runtime for BEAM languages like Erlang and Elixir, written in Rust. It targets WebAssembly as a primary compilation target, enabling BEAM language code to run in the browser and other WASM environments.

Use cases

• compile Erlang or Elixir code to WebAssembly
• run BEAM language applications in the browser
• build web apps using Elixir without a server
• experiment with alternative Erlang VM implementations
• compile BEAM languages to native executables or libraries
• embed Erlang-style concurrency in WASM environments

When to choose

• you want to run Erlang/Elixir code in WebAssembly environments like the browser
• you need a lightweight alternative to the standard BEAM VM
• you're experimenting with compiling BEAM languages to native or WASM targets

When to avoid

• you need a production-ready, fully OTP-compatible Erlang VM
• you rely on complete OTP behavior and standard library support
• you need a stable, mature toolchain for critical systems
