LINUX APP PUBLISHING
Publish Your App on Linux — Snap Store, Flathub & AppImage
SaasToStore builds all three automatically using Tauri and GitHub Actions. 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 binaries are typically under 15 MB.
- 2
GitHub Actions matrix builds all three formats
The build.yml matrix runs three jobs simultaneously: Ubuntu 22.04 for Linux (.AppImage + Snap), Windows for .msi, macOS for .dmg. All three complete in 8–12 minutes. 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 get a permanent download URL on GitHub Releases.
- 4
Snap Store — connect once, publish automatically
Connect your Snapcraft credentials in the SaasToStore dashboard. One-click publishing uploads the snap package to the Snap Store and submits it for review. Snap review: 1–3 business days.
- 5
Flathub — manifest generated, PR opened automatically
Connect your GitHub account. SaasToStore generates the Flatpak manifest (org.yourapp.App) and opens a pull request to the Flathub GitHub repository. Flathub review: 1–2 weeks. Once approved, your app is live on flathub.org.
Linux distributions supported
What's included with every Linux build
- Linux .AppImage — runs on any x86_64 distribution without installation
- Snap package — ready for Snap Store submission
- Flatpak manifest — ready for Flathub pull request
- Tauri native window — not a browser, not Electron
- Application icon + desktop entry (.desktop file)
- GitHub Release with permanent download URL
- Same build as Windows .msi and macOS .dmg — LAUNCH plan 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 40+ other Linux distributions. Over 20 million Linux users access the Snap Store monthly. 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. It distributes to over 2 million monthly active users. 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, Snap package, and Flatpak manifest automatically using Tauri and GitHub Actions. 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: 40+ 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?+
The LAUNCH plan (20 EUR one-shot) includes Android + Desktop — Windows .msi, macOS .dmg, Linux .AppImage, Snap Store, and Flathub. All five from a single build.
Three Linux distribution channels from one build
AppImage for direct download. Snap Store for 20M+ users. Flathub for 2M+ monthly active users. All three from the SaasToStore LAUNCH plan.
