Installation

FantASM ships as a single self-contained executable. Grab a prebuilt binary for your platform, or build it from source.

Prebuilt binaries

Download the latest release for your platform from the Downloads page — macOS (Apple Silicon), Windows, and Linux (.deb, Arch, or a portable tarball).

Each build is a compressed archive: unpack it and put the fantasm binary somewhere on your PATH (e.g. /usr/local/bin on macOS/Linux) so you can run it from any directory. On macOS the Apple Silicon build is signed and notarised. Every download ships with .sha256 and .md5 checksums alongside — verify before running.

Build from source

FantASM is written in Rust (2024 edition), so you’ll need a recent toolchain — Rust 1.85 or newer. Install it via rustup if you don’t have it.

git clone https://codeberg.org/twistedraven/fantasm.git
cd fantasm
cargo build --release

The binary lands at target/release/fantasm. Copy it onto your PATH, or run it in place.

Verify

Check the version to confirm the install:

fantasm --version

You should see the FantASM version banner. You’re ready for the Quick Start.
