LINUX APP PUBLISHING
Publish Your App on Linux — Snap Store, Flathub & AppImage
To publish an app on Linux, you ship it through the two Linux app stores, Snap Store and Flathub, plus a portable AppImage for every other distribution. SaasToStore builds the AppImage from your URL with Tauri and GitHub Actions, and the snap package and Flatpak manifest once those stores are set up after purchase: no snapcraft.yaml, no Linux machine required.
SaasToStore builds the AppImage with Tauri and GitHub Actions, and the snap package and Flatpak manifest once you set up those stores after purchase. No snapcraft.yaml to write, no Flatpak manifest to maintain. Paste your URL — get a native Linux app.

Three Linux distribution formats — compared
How SaasToStore builds your Linux app
The Linux build pipeline runs on GitHub Actions with an Ubuntu 22.04 runner:
- 1
Tauri wraps your web app in a native shell
SaasToStore uses Tauri — the Rust-based desktop framework — to embed your web app URL in a native Linux window. The result has its own application menu entry, taskbar icon, and system notifications. No Electron bloat — Tauri apps stay light.
- 2
A GitHub Actions matrix builds every desktop OS
The build.yml matrix runs three jobs simultaneously: Ubuntu 22.04 for Linux (.AppImage, plus the snap once the Snap Store is set up), Windows for .msi, macOS for .dmg. Linux artifacts are uploaded to a GitHub Release.
- 3
AppImage — ready immediately for direct download
The .AppImage is included with every Desktop build. It runs on any x86_64 Linux distribution without installation — users double-click it. You download it from your SaasToStore dashboard.
- 4
Snap Store — the snap package, once the store is set up
Once the Snap Store is set up after purchase, the Linux build also produces the snap package. A paid build delivers the files each store asks for; the Snap Store sets its own review time.
- 5
Flathub — the Flatpak manifest, once the store is set up
Once Flathub is set up after purchase, SaasToStore generates the Flatpak manifest (org.yourapp.App) for your submission. Flathub reviews each new app and sets its own timing; once approved, your app is live on flathub.org.
Publishing to the Snap Store and to Flathub
Linux has two main app stores, and many distributions show them right in their software center. The same desktop build serves both stores. Here is what each store is, what your app becomes there, and how publishing works.
Snap Store — your app as a snap
- Canonical's app store for Linux, at snapcraft.io
- Snap comes with Ubuntu and can be installed on many other distributions
- People get your app from Ubuntu's software center or with snap install
- Your app ships as a snap: sandboxed, and updated automatically through release channels
- Once the Snap Store is set up in the Publish tab, the desktop build packages the snap and sends it to the store
- No fee to publish
Flathub — your app as a Flatpak
- The main store for Flatpak apps, run by the Linux community, at flathub.org
- GNOME Software and KDE Discover list its apps on distributions that enable it, such as Linux Mint and Pop!_OS
- Your app ships as a Flatpak: sandboxed, and the same package on every distribution
- Once Flathub is set up in the Publish tab, SaasToStore generates the Flatpak manifest and prepares the submission
- Flathub reviews each new app and sets its own review time
- No fee to publish
Both stores take the same desktop build as your Windows and macOS installers. The app shows your live website, so content changes reach Linux users without a new build; a new icon or a new name needs one. There's no free desktop build: the free test build is an Android .apk for your own phone. What each store asks of you is listed in the Publish tab once desktop is part of your plan.
Linux distributions supported
What's included with every Linux build
- Linux .AppImage — runs on any x86_64 distribution without installation
- Snap package — once the Snap Store is set up
- Flatpak manifest — once Flathub is set up
- Tauri native window — not a browser, not Electron
- Application icon + desktop entry (.desktop file)
- Download from your dashboard (GitHub Releases)
- Same build as Windows .msi and macOS .dmg — SHIP covers all five
Frequently asked questions
What is the Snap Store?+
The Snap Store is Canonical's app distribution platform for Linux. Snap packages (snaps) run on Ubuntu, Fedora, Debian, Arch, and many other Linux distributions. Publishing is free.
What is Flathub?+
Flathub is the largest Flatpak app repository for Linux, integrated by default into GNOME Software on Fedora, Linux Mint, and elementary OS. Listing on Flathub is free for open-source and commercial apps.
What is an AppImage?+
An AppImage is a portable Linux application format — a single self-contained .AppImage file that runs on any Linux distribution without installation, without root access, and without package management. It's ideal for direct download distribution.
Do I need to know Linux packaging to publish with SaasToStore?+
No. SaasToStore builds your .AppImage with Tauri and GitHub Actions, and your Snap package and Flatpak manifest once you connect the Snap Store or Flathub after purchase. You don't write any packaging configuration.
Can my web app run as a native Linux application?+
Yes. SaasToStore uses Tauri to wrap your web app in a native Linux window — with a taskbar icon, application menu entry, and system notifications. It behaves like a native desktop app, not a browser window.
Which Linux distributions does SaasToStore target?+
AppImage: runs on any x86_64 Linux distribution (Ubuntu, Fedora, Debian, Arch, Manjaro, and more). Snap: many distributions via the Snap daemon. Flatpak/Flathub: Fedora, Linux Mint, Pop!_OS, elementary OS, and any distribution with Flatpak installed.
Is publishing to Flathub free?+
Yes. Flathub is free for both open-source and proprietary commercial apps. The review process requires submitting a Flatpak manifest via a GitHub pull request — SaasToStore generates this manifest automatically.
What plan includes Linux publishing?+
SHIP (39 EUR one-shot) includes Android, iOS and Desktop — Windows .msi, macOS .dmg, Linux .AppImage, plus Snap Store and Flathub once you connect them.
Three Linux distribution channels from one build
AppImage for direct download. Snap Store and Flathub once you set them up. All three from the SaasToStore SHIP plan.
