Pastes into your terminal and installs onyx on your macOS or Linux machine in one step — no manual setup, no build tools. It fetches the project's own install script and runs it, which is the standard way these tools ship — worth a read if you like to know what's running.
How to set up onyx, step by step
Open Terminal. On a Mac it's in Applications ▸ Utilities, or press Cmd+Space and type Terminal. On Linux, press Ctrl+Alt+T. Paste the command and press Enter.
Run onyx --help to see the available commands, and
onyx --version to confirm the install worked. If your shell complains about
permissions, that project usually documents a corrected command on its own site.
This downloads the project's shell installer and pipes it straight into your shell, which executes it without saving a file. Same caveat: it's the project's script, but read it first if you want to be sure.

onyx is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
onyx is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
