Batamanta is a packaging utility that creates 100% self-contained executable binaries from Elixir releases.

It packages your Elixir application along with the complete Erlang Runtime System (ERTS) into a single static binary, eliminating any dependency on Erlang or Elixir being installed on the target machine.

Features

• Self-contained binaries: No Erlang/Elixir installation required on target
• Cross-compilation: Build for Linux (glibc/musl), macOS, and Windows from any platform
• Compression: Uses Zstandard for optimal size/performance balance
• Multiple execution modes: CLI, TUI, and Daemon support
• Escript format: Lightweight bundling for projects using mix escript.build
• Release format: Full OTP release with supervisor tree
• Automatic Cleanup: Wipes temporary build artifacts while preserving the ERTS cache

Configuration

Add Batamanta to your dependencies and configure it in mix.exs:

def project do
  [
    app: :my_app,
    version: "0.1.0",
    deps: [{:batamanta, "~> 1.0", runtime: false}],
    batamanta: [
      format: :escript,
      erts_target: :auto,
      execution_mode: :cli,
      compression: 3
    ]
  ]
end

Then build your executable:

$ mix batamanta
