Install Facet

Facet is a Mac app. It needs no account and no sign-up, and it keeps your designs as files on your Mac.

You need a Mac with Apple silicon (M1 or later) and macOS 13 Ventura or later.

Download and open

  1. Download Facet.dmg from faux.design.
  2. Open the downloaded file. A window shows the Facet icon and an Applications folder.
  3. Drag Facet onto Applications.
  4. Open Facet from your Applications folder, Launchpad or Spotlight (⌘ Space, type "Facet").
  5. macOS asks once whether you want to open an app downloaded from the internet. Click Open.

Facet is signed and checked by Apple (notarized), so that is the only question macOS asks.

What you see first

A welcome screen with three choices:

  • Start with a sample opens a small, half-finished design you can explore, or ask your AI to finish.
  • New design starts an empty file.
  • Open… opens a design you already have.

Beside them, Let your AI design with you connects Claude, ChatGPT, Cursor or another assistant in one click. See Connect your AI. You can skip it and come back any time from Facet › Connect AI Apps…. Help › Show Welcome brings this screen back.

With Homebrew

If you already use Homebrew:

brew install --cask uxfreak/tap/facet

This installs the app and the facet command together. Updates still arrive inside the app.

Where your designs live

Designs are ordinary files ending in .facet. New designs go to Documents › Facet unless you choose another folder. Double-click a .facet file in Finder to open it, or drop it on the Facet icon. Facet keeps its settings, recent files and design systems in a hidden folder in your home folder, .facet.
