Submitting an app to be added to Pi-Apps

If you're reading this, you are probably thinking about submitting a new app to be added to Pi-Apps. Welcome! Please understand that Pi-Apps is maintained by volunteers, and we have high standards for which apps are added. As we are a small team, we value quality over quantity. We manually review each potential app for quality and usefulness to average Linux users.

If you are not sure if an app fits the guidelines, feel free to ask us before you spend a bunch of time writing scripts and a description for it! It's OK to ask first! We appreciate it.

  • The app needs to be useful for people who use their Raspberry Pi as an everyday, desktop computer.
    • Apps that are meant to run on a headless Pi will not be accepted. (Rosetta@home, pihole, etc)
    • Apps that are not designed for everyday GUI users won't be accepted. (command-line file servers, webservers, etc)
    • Low-effort apps with questionable usefulness will be rejected.
  • The app needs to be legal to download and use. (No piracy allowed)
    • Paid apps are allowed. If your app has a free demo mode (like Doom 3), please ask the user if they want the demo mode or the full version.
  • The app should be appropriate for all ages. After all, Raspberry Pi is designed with children in mind.
  • Update 2026: ARM64-only apps are perfectly fine. If the app runs on 32-bit ARM that's fine, but not required anymore.
  • The app may not have any malicious content. Any attempt to upload viruses, zip bombs, or any sort of software will result in a swift ban from all pi-apps repos and a report of such malicious activity to GitHub.
  • The app needs to look legitimate, established, and under active maintainance.
    • AI-generated apps that appear to be low quality will not be accepted.
    • Apps that appear to be beginner level coding projects with low likelihood of being maintained will not be accepted.
  • Even if your app follows all of these guidelines, there still may be a reason we decide not to add it to the official Pi-Apps repository. If that happens, you can still take advantage of Pi-Apps's features by telling your users to import the zip file for your app.

Note about Package Apps (APT and Flatpak Apps):

Pi-Apps was never intended to be a GUI for apt. The only reason we have package-apps is to avoid limiting the options for a given task. For example, if you need an image editor, the best option may be an apt package, so it's best to include them for comparison rather than giving script-apps an unfair advantage.

In other words, package apps need to compliment preexisting script-apps. A proposed package-app in a completely new category will not be accepted.

The remainder of this page will explain how to make an app.

  • First, launch Pi-Apps Settings.
  • Click New App.
  • This launches the Create App Wizard. This series of dialog boxes will guide you through the process of making your very own app.
  • It will ask for:
    • Name of app (required)
    • Icon: should be a square icon, at least 64x64 px. Note that Windows .bmp icons rarely scale properly.
    • Website: In general, the website link should point to where users will find help and more information about the app.
    • OS architecture compatibility: Select if your app is 32-bit compatible, 64-bit compatible, or both.
    • Description: Explain to a total noob user what the app is, what the app does, and how to get it running.
    • Credits: Give yourself credit for adding it to Pi-Apps! :)
  • In the subsequent pages, Pi-Apps will assist you in making your own bash scripts to install and uninstall the app.

Making an install script

What's a bash script? I'm glad you asked.
Basically, ask yourself this question: "What commands should I run in a terminal to install this app?"
Simply write down all those commands in a file Pi-Apps opens for you.
Here's the install-32 script from the Arduino app: (located at ~/pi-apps/apps/Arduino/install-32)

#!/bin/bash
version=1.8.19

cd ~/.local/share
wget https://downloads.arduino.cc/arduino-${version}-linuxarm.tar.xz || error "failed to download!"
tar -xf $(pwd)/arduino-${version}-linuxarm.tar.xz || error "failed to extract with tar!"
sudo $(pwd)/arduino-${version}/install.sh || error "failed run Arduino install script!"
rm -f $HOME/Desktop/arduino-arduinoide.desktop $(pwd)/arduino-${version}-linuxarm.tar.xz

Let's walk through the script, one line at a time.

  • First we tell our script which command language we are using, in this case it is bash, all scripts will likely have this
#!/bin/bash
wget https://downloads.arduino.cc/arduino-${version}-linuxarm.tar.xz || error "failed to download!"
  • Oh, but what's that ⏫? error? The error command is used in all Pi-Apps scripts to exit if something goes wrong. For example, if the above line failed to download Arduino for some reason, the script will stop and talk. (in the terminal, it will exit with a red error saying "failed to download!")
  • This line extracts the zipped folder we just downloaded. ⏬ (again, notice the error command that will notify us if this current command fails)
tar -xf $(pwd)/arduino-${version}-linuxarm.tar.xz || error "failed to extract with tar!"
  • This command runs Arduino's built-in installation bash script. ⏬
sudo $(pwd)/arduino-${version}/install.sh || error "failed run Arduino install script!"
  • And this remaining portion of the script will clean up unnecessary files afterwards.⏬
rm -f $HOME/Desktop/arduino-arduinoide.desktop $(pwd)/arduino-${version}-linuxarm.tar.xz
  • Notice that this ⏫ command does not have an error. That's because we don't care if this command fails.

Other things to be aware of

The Arduino app was quite simple because it already included its own installation scripts. Not all apps are like this. Below are other tips that will come in handy when making your own apps, or understanding other pre-made install scripts.

  • To download a github repository, you can't use wget. Use the git clone command instead. For example, git clone https://github.com/Botspot/pi-apps, which will download the git repository to the ~/pi-apps folder by default. (As usual, add an || error clause at the end in case the download fails.)
  • To install a package, don't use apt! Doing this causes problems, no matter which approach you try:
    • Your app could install the ffmpeg package when installing the app, and uninstall ffmpeg when uninstalling the app. What's the problem here? Some people will already have ffmpeg installed on the system, and they will be quite annoyed when it goes missing after uninstalling your app.
    • To solve the above issue, your app could only install the ffmpeg package, and not even try to uninstall it. This solution would work, but it's a very bad choice, both for disk usage, and for the Pi-Apps policy where users expect an uninstall script to undo everything.
    • Solution: don't use apt. Use Pi-Apps's install_packages function. install_packages uses apt, but it records which packages each app installs. When you uninstall the app, the purge_packages script will uninstall these packages that were written down earlier.
      install_packages usage:
      install_packages package1 /path/to/package2.deb https://example.com/package3.deb package4-* || exit 1

      That ⏫ is roughly equivalent to something like sudo apt update && sudo apt install -y package1 package2 package3 || exit 1
      And to remove all packages your app installed earlier:
      purge_packages || exit 1
  • Shortcut: create small text files using echo inside the install script. Many scripts use this technique to create menu button files:
echo "[Desktop Entry]
Name=Ultimaker Cura
GenericName=3D Printing Software
Comment=Cura converts 3D models into paths for a 3D printer. It prepares your print for maximum accuracy, minimum printing time and good reliability with many extra features that make your print come out great.
Exec=/opt/Cura.AppImage %f
Icon=$(dirname $0)/icon-64.png
Terminal=false
Type=Application
MimeType=application/sla;application/vnd.ms-3mfdocument;application/prs.wavefront-obj;model/x3d+xml;model/stl;
Categories=Graphics;Education;Development;Science;
Keywords=3D;Printing;
StartupNotify=true" | sudo tee /usr/share/applications/cura.desktop

This ⏫ was taken from the Cura app's install-32 script. It creates a file at /usr/share/applications/cura.desktop. (Don't forget to make the uninstall script remove it!)

  • Delete files with rm /path/to/file-i-wanna-delete.txt. It's good practice to use rm -f to hide errors in case the file doesn't exist. For deleting entire folders, use rm -rf.
  • Move files to the Trash with gio trash /path/to/file/or/folder-i-wanna-delete.

Making an uninstall script

It should undo all changes made during installation, with one exception: uninstalling an app must not delete the app's configuration files. We don't want people's Minecraft worlds being deleted during an update.
Here's the Arduino app's uninstall script. ⏬

#!/bin/bash
VERSION=arduino-1.8.19

if [ -f "$HOME/.local/share/$VERSION/uninstall.sh" ]; then
  sudo $HOME/.local/share/$VERSION/uninstall.sh || error "Failed to run Arduino uninstall script!"
  rm -rf $HOME/.local/share/$VERSION || error "Failed to remove $HOME/.local/share/$VERSION folder"
elif [ -f "$HOME/.local/share/$VERSION/install.sh" ]; then
  #there is an option to uninstall Arduino in its install script, if uninstall script not found, use sudo $VERSION/install.sh -u instead
  sudo $HOME/.local/share/$VERSION/install.sh -u || error "Failed to run sudo ~/.local/share/$VERSION/install.sh -u"
  rm -rf $HOME/.local/share/$VERSION || error "Failed to remove $HOME/.local/share/$VERSION folder"
else
  echo "WARNING: Arduino's install and uninstall script were not found! Most likely it was never fully installed. Removing $HOME/.local/share/$VERSION folder..."
  rm -rf $HOME/.local/share/$VERSION || error "Failed to remove $HOME/.local/share/$VERSION folder"
fi

Script explanation:

  • These run scripts that have resided in Arduino's folder. ⏬ They will remove the menu buttons for us and take care of most of the uninstall process.
sudo $HOME/.local/share/$VERSION/uninstall.sh
  • And this will delete the Arduino folder if the uninstall and install scripts are not found. ⏬
rm -rf $HOME/.local/share/$VERSION
