Download

The button picks the macOS, Windows or Linux build automatically; Android and iOS are listed below along with every other format.

macOS:

Download Foxl for Mac (Universal)

The universal build works on both Apple Silicon and Intel Macs.

Or with Homebrew: brew install --cask foxl-ai/tap/foxl. The cask is updated as part of every release and installs the same universal build.

Windows:

Download Foxl for Windows (Installer)

NSIS installer with auto-update support.

Download Foxl for Windows (Portable ZIP)

No installation needed. Extract and run.

Linux:

Download Foxl for Linux (AppImage)

A single self-contained file - no package manager, no root.

Android:

Download the Android APK

The Android app ships from this same release. See Mobile Apps for iOS.

Installation

macOS

1. Open the downloaded .dmg file
2. Drag Foxl to your Applications folder
3. Open Foxl from Applications
4. On first launch, macOS may ask you to confirm - click "Open"

Windows

Installer: Run Foxl-latest-setup.exe and follow the prompts. Foxl will be installed and a desktop shortcut created.

Portable: Extract the ZIP and run Foxl.exe. No installation required.

Linux

1. Make the file executable: chmod +x Foxl-latest.AppImage
2. Run it: ./Foxl-latest.AppImage

If it stops with dlopen(): error loading libfuse.so.2, the AppImage runtime needs FUSE 2, which Ubuntu 22.04 and later no longer install by default: sudo apt install libfuse2 (on Ubuntu 24.04 the package is libfuse2t64), then run it again.

Sign In

After launching Foxl, sign in with Google, Apple, GitHub, or email - a magic link, or a password if you have set one.

Then connect a model in Settings > Model & provider - Foxl is free and the model access is yours to supply, so this is the one setup step that matters. Your own API key, a local model, or a Claude / ChatGPT subscription you already pay for all work; see Cost & model access.

First run

A new install opens on a short setup over the live app: pick light, dark or system and one of nineteen colour themes, then optionally say what you do and how technical an answer you like, followed by a short tour: cards pointing at Schedules, Agents and Chat, and on the desktop app a fourth at the Model & provider pane, because a fresh desktop cannot chat until a provider is connected. Nothing is required - Continue works with nothing selected, and "Skip all" or Escape leaves at any point. An install you have already used never sees it; Settings > Appearance has a Show setup again button that replays it, and below that a Reset onboarding row that forgets setup was completed on this device and returns to the main screen, where it starts over.

The phone apps go straight from sign-in into the product and skip this; see Mobile Apps.

Appearance

Foxl follows your system light/dark setting by default. To pin it, open Settings > Appearance and choose Light, Dark, or System. The same section holds nineteen colour themes and fifteen Surfaces - see Appearance for the full set. The choice applies to the desktop app, app.foxl.ai, and the phone apps.

On macOS 26 (Tahoe) and later the window's outer chrome is a real translucent material, so your desktop shows through behind the sidebar while the content stays opaque and readable. Older macOS, Windows, and Linux get the standard opaque window - nothing else changes.

Auto-Updates

Foxl automatically checks for updates and installs them when you quit the app. You'll always have the latest version.

If an install does not complete - something was still holding the app when the installer got there - Foxl notices on the next launch and says so in the bell and in Settings, with an offer to try again, rather than restarting you silently onto the old version.

Beta updates

Settings > General, under Updates, has a Beta updates switch that offers beta builds as soon as they are put out, a release ahead of everyone else.

• A beta is the same Foxl, signed the same way, on your normal account and your normal data. It is not a separate environment or a test server - only the app is ahead.
• When the matching stable release ships you move onto it automatically, so you are never stranded on an old beta.
• Turning the setting off keeps you on the build you are running until that stable release arrives; it does not put you backwards.
• Betas are published as prereleases, so with the setting off you will never be offered one, and the download links above always point at the stable release.
