Aftman is a toolchain manager. It enables installing project-specific command line tools and switching between them seamlessly.
$ rojo --version
Rojo 6.2.0
$ cat ~/.aftman/aftman.toml
[tools]
rojo = "rojo-rbx/rojo@6.2.0"
$ cd uses-rojo-7
$ rojo --version
Rojo 7.1.0
$ cat aftman.toml
[tools]
rojo = "rojo-rbx/rojo@7.1.0"
You can install Aftman from crates.io using Rust 1.58.0 or newer:
cargo install aftman
On Windows, you should then run
aftman self-install
This will install Aftman to its own bin directory and update the PATH
environment variable for you.
On other platforms, you'll need to add Aftman's bin directory to your system PATH
:
- On Windows:
%USERPROFILE%\.aftman\bin
- On Linux or macOS:
~/.aftman/bin
To create a new aftman.toml
file in your current directory, run
aftman init
To add a new tool, you can follow the instructions in the file, or run
aftman add rojo-rbx/rojo
# install a specific version
aftman add rojo-rbx/rojo@6.2.0
# install with a different binary name
aftman add BurntSushi/ripgrep rg
If your PATH is configured correctly (see Installation), you will now be able to run that tool from your project.
To install a tool system-wide so that it can be used anywhere, edit ~/.aftman/aftman.toml
or run
aftman add --global rojo-rbx/rojo
To install all tools listed by your aftman.toml
files, run
aftman install
Aftman supports:
- Windows (x86, x86-64)
- macOS (x86-64, AArch64)
- Linux (x86, x86-64)
For detailed help information, run aftman --help
.
Usage:
aftman init [path]
Creates a new aftman.toml
file in the given directory. Defaults to the current directory.
Usage:
aftman add [--global] <tool-spec> [tool-alias]
Installs a new tool with the given tool spec and optional alias to use for installing the tool.
Examples:
# Install the latest version of Rojo in the nearest aftman.toml file
aftman add rojo-rbx/rojo
# Install the latest version of Rojo globally
aftman add --global rojo-rbx/rojo
# Install a specific version of Rojo locally
aftman add rojo-rbx/rojo@6.2.0
# Install Rojo with a different binary name
aftman add rojo-rbx/rojo@6.2.0 rojo6
Usage:
aftman install [--no-trust-check]
Install all tools listed in aftman.toml
files based on your current directory.
If --no-trust-check
is given, all tools will be installed, regardless of whether they are known. This should generally only be used in CI environments. To trust a specific tool before running aftman install
, use aftman trust <tool>
instead.
Usage:
aftman self-install
Installs Aftman, upgrades any references to Aftman, and adds aftman
to your system PATH
if supported.
Whenever you upgrade Aftman, run this command. Aftman makes copies of itself to mimic the tools it installs, and this command will ensure those copies get updated as well.
Usage:
aftman trust <tool-name>
Adds a tool to the list of trusted tools.
Aftman prompts the user before installing new tools. Running aftman trust
beforehand skips this prompt. This is useful when running automation that depends on a tool from a known location.

Aftman is spiritually very similar to Foreman, a project I created at Roblox.
I'm hoping to fix some of the core design mistakes I made in Foreman and also take a little more care with the codebase. Roughly:
- Exact version dependencies. Using a range here has tripped up lots of users, so Aftman uses exact versions in all configuration files.
- Commands to install, uninstall, and upgrade tools. Editing a global, tucked-away toml file by hand is rough.
- Change model to no longer trust-by-default. Aftman prompts before downloading new tools. (Roblox/foreman#16).
- Better strategy for storing executables. (Roblox/foreman#11)
- Better heuristics for picking the right artifacts for your platform. Aftman uses your Compiler, OS, architecture, and will eventually support custom patterns. (Roblox/foreman#18)
- Proper error handling. Unlike Foreman, which uses
Result::unwrap
liberally, Aftman has good error hygeine with helpful context attached. - Less Roblox-angled. Aftman does not market itself as being for Roblox development. It is a generally useful tool that can install all sorts of CLI tools.
