Download Orizon

In the browser on any device, and as an app for Linux. The Android app is in testing.

Last updated: 25 September 2026

Orizon works right away in the browser and as an app for Linux. The Android app is in closed testing and the iOS one is in the works: we would rather release them when they work well than in a hurry.

Available now

In the browser, on any device

Open app.4orizon.eu from a computer, tablet or phone. There is nothing to install, and encryption works exactly as it does in the apps.

Open Orizon

On Linux computers

Orizon for 64-bit Linux, with voice and video calls. Choose the package for your distribution:

Debian, Ubuntu, Linux Mint
Download .deb

Fedora, openSUSE
Download .rpm

Arch, Manjaro, EndeavourOS
Download .pacman

Any distribution, no installation needed
Download .tar.gz

You need an up-to-date distribution: Ubuntu 22.04 or later, Debian 12 or later, or a recent Fedora or Arch. All versions, including older ones, are in the releases on GitHub.

On Debian, Ubuntu, Mint, Fedora and openSUSE, just double-click the downloaded file. From a terminal, in the folder where you downloaded it:

sudo apt install ./orizon-desktop_1.12.13-2_amd64.deb
sudo dnf install ./orizon-desktop-1.12.13-2.x86_64.rpm
sudo pacman -U orizon-desktop-1.12.13-2-x86_64.pacman

Verifying the package

Before installing, you can check that the file is exactly the one we published and that nobody has altered it along the way. Compute its fingerprint, for example:

sha256sum orizon-desktop_1.12.13-2_amd64.deb

The result must match the one for your package, character for character:

The same fingerprints are also published in the SHA256SUMS.txt file of the GitHub release: two independent sources that must say the same thing.

Installing it on your phone from the browser

Until the phone apps are public, you can add Orizon to your home screen and use it like a normal app, full screen and with its own icon.

  • Android: open the site in Chrome, tap the menu and choose "Install app" or "Add to Home screen".
  • iPhone: open the site in Safari, tap the share button and choose "Add to Home Screen".

Want to try the Android app

It is in closed testing on Google Play. If you would like to try it before release, write to info@4orizon.eu with the address of your Google account and we will add you to the testers. We will use your address only for that.

Requirements

  • In the browser: Chrome, Firefox, Safari or Edge in a recent version, with JavaScript enabled, which encryption needs in order to work.
  • On Linux: a 64-bit Debian-based distribution.
