embala

One config, multiple installers: .msi, setup.exe, .app, .pkg and Chocolatey .nupkg, written natively from any host OS. No WiX, no Wine, no macOS required. embala packages prebuilt artifacts; it never compiles.

embala build                      # every format with a section in embala.toml
embala build --formats msi,nupkg  # a subset, into dist/

A minimal embala.toml:

[package]
name = "hello"
display-name = "Hello"
version = "1.0.0"
identifier = "com.example.hello"
publisher = "Example"
description = "Example app"

[msi]
arch = "x86_64"
main-executable = "hello.exe"
files = [{ src = "dist/hello.exe", dest = "hello.exe" }]
# Optional: register a payload file as a Windows service.
# service = { name = "hello", start = "auto", arguments = "--service", executable = "agent.exe" }
# Optional: append the install directory to the system PATH.
# add-to-path = true

Prebuilt binaries, the full config reference and signing notes are in the repository. The format writers are separate crates: embala-msi, embala-pkg, embala-nupkg, embala-setup.
