Install.

Prebuilt artifacts are attached to each GitHub Release.

macOS

abstract-<version>-macos-aarch64.dmg (Apple Silicon) or ...-macos-x86_64.dmg (Intel) — open and drag abstract to Applications. A .app.zip alternative is attached too. Builds are ad-hoc signed (no Apple Developer ID), so Gatekeeper blocks the first launch: right-click → Open, or run:

xattr -dr com.apple.quarantine /Applications/abstract.app

Linux

abstract-<version>-linux-x86_64.tar.gz (binary + docs), a .deb, an .rpm, or an .AppImage. aarch64 builds are attached as abstract-<version>-linux-aarch64.*. Works on Wayland and X11.

Arch / CachyOS (AUR)

paru -S abstract-editor      # build from source
paru -S abstract-editor-bin  # prebuilt binary

Download the .deb from the latest release, then:

sudo dpkg -i abstract-editor_<version>_amd64.deb
