subsurface-4.9.4.exe has been tested on a number of 32 and 64 bit versions of Windows, including Windows 7, Windows 8 and Windows 10.


Subsurface-4.9.4.dmg is a Mac image that can be installed on 64bit Intel Macs running MacOS 10.10 or later by dragging the to your /Applications folder.


The Subsurface team is making our own dedicated binaries available for a number of Linux versions as well as a generic “AppImage” that should work on most any Linux distribution.

Ubuntu (16.04 and 18.04), LinuxMint (18), and Debian Stretch

To use these binaries in Ubuntu, simply add the following PPA to your system:


On LinuxMint you have to add this on the command line and explicitly request the PPA version of Subsurface, otherwise the outdated Subsurface 4.0 would have been installed:

sudo apt-add-repository ppa:subsurface/subsurface
sudo apt-get update
sudo apt-get install subsurface=4.9.4-1~xenial

For Debian Jessie you need to add the Ubuntu repository:

echo "deb xenial main" 
        | sudo tee /etc/apt/sources.list.d/subsurface.list
gpg --keyserver --recv-keys A8BC9756EE61D9C6
gpg -a --export A8BC9756EE61D9C6 | sudo apt-key add -
sudo apt-get update

For distributions who only support the older Subsurface version replace xenial with trusty.
Now you can install Subsurface from that repository:

sudo apt-get install subsurface

Make sure you are getting a current version with all its Qt5 dependencies.

OpenSUSE Leap 42.3, Leap 15.0, Tumbleweed and Fedora 27, 28, 29, and rawhide

To install the official Subsurface package under these OpenSUSE or Fedora versions, go to our build service project page and follow the simple instructions there -- it’s as easy as two clicks.

All other 64bit Linux versions

A generic AppImage is available for download as Subsurface-4.9.4-x86_64.AppImage. You should be able to download this file, make it executable chmod +x Subsurface-4.9.4-x86_64.AppImage and then simply run this file. We are very interested in feedback regarding this way of distributing Linux binaries.

Deprecated distribution maintained packages

Some flavors of Linux allow an install of Subsurface from within the OS. While this is very convenient, we recommend that you use the official packages as described above.


Sources are of course available via git or as a release tar-ball Subsurface-4.9.4.tgz. The sources of the GPL and LGPL components shipped with the Mac and Windows binaries can be found at MacPorts and MinGW.
