The universal build, package, and publishing tool.

Koca is a modern, universal, and system-native package manager designed to simplify the process of building and distributing applications across multiple platforms. It is so powerful that it even builds and packages itself!

• Universal: Build for any operating system—Windows, macOS, and Linux distributions (Ubuntu, Debian, Red Hat)—using a single build file.
• System Native: Leverage native packaging systems to output familiar formats like .exe, .pkg, .deb, .rpm, and more.
• Lightning Fast: Optimized for speed with a Rust-based backend, ensuring your builds are as fast as possible.
• Developer First: Focus on building your application, not the packaging tooling around it.

Koca uses a simple, bash-like syntax for its build files. Here is an example of how you can package Claude Code using Koca:

pkgname=claude-code
pkgver=2.1.50
pkgrel=1
pkgdesc='Terminal-based AI coding assistant'
arch=('x86_64')

build() {
    # Download the pre-built Claude Code binary, using the version we defined above with Bash variable syntax
    curl -L "https://storage.googleapis.com/claude-code-dist-86c565f3-f756-42ad-8dfa-d59b1c096819/claude-code-releases/${pkgver}/linux-x64/claude" -o claude
    chmod +x claude
}

package() {
    # Koca provides the $pkgdir environment variable to stage your package
    install -Dm 755 "claude" "${pkgdir}/usr/bin/claude"
}

To create a package from this script:

# Create a .deb and .rpm package for Claude Code
koca create claude-code.koca --output-type all

You can download the latest pre-built binaries for your platform from the GitHub releases page.

If you have Rust and Cargo installed, you can build and install Koca from source:

cargo install koca-cli

You can also run Koca as a Docker container:

docker run --rm -v $(pwd):/workspace ghcr.io/koca-build/koca create /workspace/your-app.koca

The create command is the primary way to build packages:

# Create .deb and .rpm packages (default)
koca create your-app.koca

# Create an .rpm package
koca create your-app.koca --output-type rpm

Koca is released under the FSL-1.1-MIT license.
