Please go to the download section on the website

On Linux: Be sure to install all the gstreamer packages on your system to be able to use the mediaplayer. Problem with the AppImage ? Check the wiki or file an issue

On MacOS: After opening/mounting the DMG image, hold Control and click on the galacteek icon, and select Open and accept. You probably need to allow the system to install applications from anywhere in the security settings. Create an issue if you have problems running the DMG image.

On Windows: GIT is not packaged in the installer. Install it here. If you run into an issue with the installer, please create an issue here .

You'll need to have git installed to sync hashmarks repositories.


Docker images are available. They run the full GUI inside a virtual Xorg server (using Xvfb). A VNC server runs on TCP port 5900 of the container, just use a regular VNC client to access the interface. The password to access the VNC service is printed to the console when starting the container.

Pull the image and run it with:

docker pull
docker run -p 5900:5900 -t

If you want to persist the container's galacteek data on your system, use the following:

mkdir /usr/local/galacteek-docker
docker run -p 5900:5900 -v /usr/local/galacteek-docker:/home/galacteek -t

Open your VNC client using the container's IP address (port 5900) using the password issued on the container's console.

You can view all the available docker images here in the container registry.

Browsing the Wikipedia mirror over IPFS

Browsing the Wikipedia mirror over IPFS


galacteek can either spawn an IPFS daemon and use it as transport, or connect to an existing IPFS daemon. By default it will try to run a daemon. You can change the IPFS connection settings by clicking on the settings icon in the toolbar and restart the application afterwards. If using a custom daemon, you should enable pubsub and p2p streams, or some features won't be available (Check this page for more information).

  • Decentralized Identifiers (DID) support with IPID
  • Semantic dweb agent (distributed RDF graph)
  • Browser-to-browser DID authentication over libp2p streams (Verifiable Credentials with RSA-PSS)
  • Browsing sessions with automatic pinning (pins every page you browse)
  • Distributed chat with pubsub (chat channels syncronized with CRDT+DAG)
  • Support for remote pinning services
  • File manager with drag-and-drop support and timeframes (per-day view of files in the MFS)
  • File sharing
  • BitTorrent to IPFS bridge
  • Gemini support
  • Tor support
  • Simple messenger based on the Bitmessage protocol
  • Search content with the ipfs-search search engine as well as with cyber
  • Built-in blog with Atom feeds
  • Webcam to IPFS capture (image and videos)
  • Basic built-in media player with playlists based on linked-data
  • Image viewer and QR codes support
  • Use the IPFS filestore to avoid file duplication
  • ENS (Ethereum Name Service) resolving (access to ENS+IPFS websites)
  • Run WASM binaries with wasmer (use Open on a WASM object from the clipboard manager)

Command-line usage

Use the -d command-line switch to enable debugging output. Using --profile gives you the ability to have separate application profiles (main is the default profile). Use --help for all options.

If you've changed some settings and want to go back to the default configuration, use --config-defaults.

You can run the IPFS daemon in offline mode, using --offline

Time-rotated log files can be found in the $HOME/.local/share/galacteek/main/logs directory

Enable colorized log output with --log-color

Development: Use --monitor to enable event-loop monitoring with aiomonitor (install aiomonitor manually as it's not a dependency). Then connect to the aiomonitor interface with nc localhost 50101

Keyboard shortcuts

Please see the shortcuts page (or from the application, click on the Information icon in the toolbar, which will open the documentation).


For instructions on how to build the application, look at the BUILDING page.


Contributions that can help:

  • Write DID services
  • UI translations (French, Spanish)
  • Manual translations (French, Spanish)

Platforms supported

  • Linux (x86_64) (main target)
  • Linux (aarch64). If you have a Raspberry PI (64-bit), check the Raspberry page.
  • Any BSD operating system (with manual build)
  • MacOS

Unofficially supported:

  • Windows: although an installer is provided, no special effort will be put in maintaining support for this platform. Not all features will work. By all means use Linux and you'll enjoy the full experience.

Because of the nature of the software's stack (asyncio/Quamash), support for any other platform is unlikely.


  • python3 >= 3.7 (Works with python 3.7, 3.8, 3.9)
  • go-ipfs >= 0.5.0 (the installers include go-ipfs version 0.9.0)
  • PyQt5 >= 5.13.2
  • PyQtWebengine >= 5.13.2
  • gstreamer (on Linux) for media player support
  • git
  • asyncqt
  • aiohttp
  • aioipfs
