Installation

Choose the build for your operating system and CPU architecture from Download Athas. Use stable releases for everyday work; see Updates for upgrades.

Quick Install

bash

curl -fsSL https://athas.dev/install.sh | sh

If you prefer wget:

bash

wget -qO- https://athas.dev/install.sh | sh

The install script detects your OS and architecture, downloads the latest stable release from GitHub by default, verifies the SHA256 checksum when available, and installs it. To install a specific release, pass its version:

bash

curl -fsSL https://athas.dev/install.sh | sh -s -- --version 0.15.1

On macOS, the script installs Athas to /Applications. On Linux, it installs the app bundle to ~/.local/share/athas/athas.app and links the executable at ~/.local/bin/athas.

On Linux, Athas uses the system WebKitGTK 4.1. The script checks for it and, if it is missing, prints the command to install it instead of installing an app that cannot start:

Distribution	Package
Debian, Ubuntu	`libwebkit2gtk-4.1-0`
Fedora	`webkit2gtk4.1`
Arch Linux	`webkit2gtk-4.1`
openSUSE	`libwebkit2gtk-4_1-0`

Linux Package Repositories

Athas publishes signed APT and DNF repositories for x64 and ARM64. Once the repository is set up, your system package manager installs Athas and picks up each stable release with its regular upgrades.

Add the signing key and the repository, then install Athas:

bash

sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://athas.dev/apt/athas.gpg | sudo tee /etc/apt/keyrings/athas.gpg > /dev/null
echo "deb [arch=amd64,arm64 signed-by=/etc/apt/keyrings/athas.gpg] https://athas.dev/apt stable main" \
  | sudo tee /etc/apt/sources.list.d/athas.list > /dev/null
sudo apt update
sudo apt install athas

Update Athas with the rest of your system:

bash

sudo apt update && sudo apt upgrade

Both repositories are signed with the Athas Packages key ([email protected]), fingerprint 9D96 7A0C 00D8 DC21 1F23 695B 9548 A14F 4E5A 0666. They track stable releases only, and the package files are the same ones attached to each GitHub release.

Package Managers

bash

brew install --cask athas

The Homebrew cask and the athas-bin AUR package are maintained by the community. Athas does not publish a Nix package; community packages may exist. WinGet and Scoop packages are on the way; until then use the PowerShell command above or the Windows installer.

Manual Download

Download the latest version from GitHub releases:

Download from GitHub Releases

Download the .dmg file from releases
Open the downloaded file
Drag Athas to your Applications folder
Open Athas from Applications

Verify the install

Open Athas, open a project folder, save a test file, and open the terminal. Install the shell command from Settings > General > Terminal Command, then run athas --help in a new shell. If the app will not launch, record the exact error and package format for Troubleshooting.

Uninstall

Quit Athas before uninstalling. Removing user-data directories also removes local settings and history; export or back up anything you want to keep first. Removing only the application preserves its user data. Use the package manager that installed the app when possible.

bash

rm -rf /Applications/Athas.app

Optional: permanently remove local settings/history and cache after backing them up:

bash

rm -rf ~/Library/Application\ Support/com.code.athas
rm -rf ~/Library/Caches/com.code.athas
