Why Linux app installation finally got simpler
Distro-hopping used to be the answer when something didn’t run on your system. In 2026 that’s barely an argument: Flatpak runs everywhere, Snap is on the major distros, and AppImage handles the edge cases. The choice now is which front-end you point at all of that.
Here are seven Linux app installers that ship on desktop in 2026, with notes on which one fits which workflow.
What to look for in a Linux app installer
- Format support. Flatpak, Snap, and AppImage are the three formats most upstream developers actually publish.
- Sandboxing. Every modern installer should isolate apps; some do it better than others.
- Updates. The right installer queues and applies updates without breaking your session.
- GUI vs CLI. Most users want a store; power users want an inspectable command.
Quick comparison
| App | Best for | Formats | Free plan | Distro support |
|---|---|---|---|---|
| Flathub | the cross-distro standard | Flatpak | Yes | Universal |
| Snap Store | Ubuntu-first apps | Snap | Yes | Ubuntu and derivatives |
| GNOME Software | GNOME desktops | Flatpak, Snap, deb/rpm | Yes | GNOME-based distros |
| KDE Discover | KDE desktops | Flatpak, Snap, deb/rpm | Yes | KDE-based distros |
| AppImageLauncher | portable apps | AppImage | Yes | Universal |
| Pop!_Shop | Pop!_OS users | Flatpak, deb | Yes | Pop!_OS |
| Distrobox | running apps from other distros | OCI containers | Yes | Any distro with podman or docker |
The apps
1. Flathub — the cross-distro standard
Flathub is the de facto Flatpak repository and the closest Linux has to a universal app store. Most major desktop apps publish here, sandboxing is enforced by Portal APIs, and updates are atomic.
Where it falls short: Sandboxing sometimes breaks file access between apps. Not every app’s Flatpak version is the same as the upstream version.
Pricing:
- Free: Public repository.
Distros: Universal (Flatpak supported on Fedora, Ubuntu, Arch, openSUSE, Debian, and more).
Download: Flathub
Bottom line: Add this first on any distro. It covers most desktop apps.
2. Snap Store — Ubuntu-first apps
Snap Store is Canonical’s installer. It’s the only place to get certain Ubuntu-blessed builds (Chromium, recent Firefox snaps, some IDEs) and integrates tightly with Ubuntu Core for IoT and server use.
Where it falls short: Slower app startup is a perennial complaint. Snap’s central store backend isn’t open like Flatpak’s.
Pricing:
- Free: Public store.
Distros: Ubuntu, Ubuntu derivatives, optional install on Fedora, Arch, openSUSE.
Download: Snap Store (snapcraft.io)
Bottom line: Useful on Ubuntu. Optional on everything else.
3. GNOME Software — GNOME desktops
GNOME Software is the front-end for GNOME-based distros (Fedora, Ubuntu GNOME, Debian GNOME). It surfaces Flatpak, Snap (where enabled), and native packages in one search.
Where it falls short: Slow to refresh metadata. Some users disable its background daemon to free memory.
Pricing:
- Free.
Distros: Fedora, Ubuntu (GNOME), Debian, and others using GNOME.
Download: Bundled with GNOME desktops. Source on the GNOME GitLab.
Bottom line: Use this on GNOME distros where it ships preinstalled.
4. KDE Discover — KDE desktops
KDE Discover is the equivalent on KDE Plasma. It handles Flatpak, Snap (optional), Plasma widgets, and native packages.
Where it falls short: Some users prefer the command line over Discover’s slower UI. Edge cases around Plasma 6.x add-ons take a few clicks to surface.
Pricing:
- Free.
Distros: KDE Plasma desktops (Kubuntu, openSUSE, Manjaro KDE, Fedora KDE).
Download: Bundled with KDE Plasma. Source on the KDE GitLab.
Bottom line: Use this on KDE-based distros where it ships preinstalled.
5. AppImageLauncher — portable apps
AppImageLauncher turns AppImage files into proper desktop entries. Double-click an AppImage and it offers to integrate it (add to your menu, manage updates) or run it once and forget.
Where it falls short: AppImage as a format doesn’t sandbox. You’re responsible for trust on each binary.
Pricing:
- Free.
Distros: Universal.
Download: AppImageLauncher (GitHub)
Bottom line: Install this if upstream developers ship AppImages and you want them to behave like installed apps.
6. Pop!_Shop — Pop!_OS users
Pop!_Shop is System76’s app store for Pop!_OS. It surfaces Flatpak and deb packages and integrates with the Pop!_OS recovery and update flow.
Where it falls short: Pop!_OS-specific. Not useful outside the System76 ecosystem.
Pricing:
- Free.
Distros: Pop!_OS.
Download: Bundled with Pop!_OS. Source on the System76 GitHub.
Bottom line: Use this if Pop!_OS is your distro.
7. Distrobox — running apps from other distros
Distrobox runs containerized distributions on top of your host. Need a tool that only ships as an Arch package? Spin up an Arch container. Need a CentOS-only build? Same idea. The host stays stable, the tools come from wherever they’re published.
Where it falls short: No GUI store. You install packages inside the container with the container’s native package manager.
Pricing:
- Free.
Distros: Any with podman or docker.
Download: Distrobox (GitHub)
Bottom line: Install this if you regularly need software from a distro you don’t run.
How to pick the right one
- If you want the cross-distro standard: Flathub (Flatpak) on top of whatever your distro ships.
- If you’re on Ubuntu: Snap Store plus Flathub.
- If you’re on Fedora GNOME or KDE: GNOME Software or KDE Discover plus Flathub.
- If you frequently use AppImages: AppImageLauncher.
- If your daily driver is Pop!_OS: Pop!_Shop.
- If you need software from another distro: Distrobox.
FAQ
What is the best way to install apps on Linux in 2026?
For most people, Flathub plus whatever GUI store your distro ships (GNOME Software or KDE Discover). Use Distrobox for niche tools and AppImageLauncher when upstream ships an AppImage.
Is Flatpak better than Snap?
Flatpak is community-governed and has wider third-party repository support. Snap is faster to publish for Ubuntu-first developers. Most desktop users prefer Flatpak.
Do I need AppImageLauncher to run AppImages?
No. AppImages run if you chmod +x them and double-click. AppImageLauncher makes them behave like installed apps with menu entries and update prompts.
Is Distrobox sandboxed?
Distrobox uses podman or docker. Containers are isolated from each other, but they share your home directory by default, so it’s not full sandboxing.
Can I use Snap on Fedora?
Yes, by installing the snapd package. But Fedora’s defaults steer toward Flatpak, and most users follow that path.
