Current "Occasional" Release: 6.0.5738

2026-10-04

The releases on this page are what we consider the current release builds of Subsurface.

We expect these builds to be reasonably stable and somewhat tested, and try to update them about once a quarter (the actual frequency may vary).

If you are looking for more "bleeding edge" releases builds, please check out the Latest Release Page.

This Subsurface Windows installer should be signed - and while it will warn you about the installation, it should be less scary warnings as with the latest builds.
This is the next generation Windows installer that adds more features and uses newer libraries - this will be the default version soon.
We try to post a signed Subsurface macOS DMG here. If your Mac doesn't want to install this image, please let us know in the User Forum. The default binaries are for Apple Silicon Macs. There's also a binary for Intel Macs, and a binary that matches the earlier, Qt 5 - based Intel releases.

Subsurface-mobile for Android is available in the Google Play store, additionally we make APKs available here. The Subsurface Android APK can be side-loaded on most Android devices.

If you would like to get automatic updates, you can use Obtainium. After installing it, click on this link on your device to add the current release version of Subsurface-mobile to Obtainium, and get update notifications when new versions are released.

Note: If you previously had installed Subsurface-mobile from the Google Play store, the first time you switch to a side-loaded app, you'll have to uninstall the Play store version. Make sure your data is synced to the Subsurface Cloud. After you install this APK and log in to the Subsurface Cloud again, the data will be restored. Every subsequent update will not require an uninstall.

A brief explanation of the concept of side-loading can be found in this androidcentral article.

iOS is the only platform right now where in general side-loading or installing unsigned binaries is impossible (apparently that may change for users in the EU, but not elsewhere). As a result we cannot make new versions of Subsurface-mobile for iOS available here, but the goal is to update the AppStore version to the "weekly" versions reasonably frequently as well.

Linux

The Subsurface team is providing distribution packages for Ubuntu and Fedora as well as a Snap and a generic "AppImage" that should work on most other x86_64 Linux distributions.

Debian

There is a version of Subsurface for debian that is maintained by a community contributor.

For the initial setup follow the instructions on https://dfx.at/subsurface-debian/, and then install Subsurface with sudo apt install subsurface.

Ubuntu and compatible distros

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

sudo add-apt-repository ppa:subsurface/subsurface; sudo apt update

and then install Subsurface with sudo apt install subsurface

Fedora

To install the Subsurface CICD binaries on Fedora simply run

sudo dnf copr enable dirkhh/Subsurface

and then install Subsurface with sudo dnf install subsurface

Arch

To install the Subsurface CICD binaries on Arch Linux you can use the AUR package which packages the AppImage.

Other x86_64 Linux distributions

The 'candidate' Snap-channel contains our current build.
A generic AppImage is available. After you download this file, make it executable chmod +x Subsurface-6.0.5738-CICD-release.AppImage, and then simply run this file.
