Snap vs Flatpak 2025: Which Universal Package Format Is Better?

In the Linux world, software fragmentation has always been one of the biggest challenges. Developers had to package their apps for .deb (Debian/Ubuntu), .rpm (Fedora/RHEL), and countless other formats. The solution? Universal packages. Two titans have risen to the top of this battle: Snap (backed by Canonical) and Flatpak (community-driven, with strong ties to Fedora/Red Hat). But in 2025, these two formats are no longer just competing for the same crown; their paths are increasingly diverging. In this Snap vs Flatpak 2025 analysis, we’ll explore their key differences, security models, and surprising new directions.

The debate is no longer just about whether the centralized Snapcraft store is better than the open Flathub. It’s now a question of whether you need a package for a desktop app or for an optimized AI model on a server. Let’s dive into a detailed Snapcraft vs Flathub comparison and find out which of these Linux universal packages deserves a place on your system.

What Are Snap and Flatpak?

Before we dive in, let’s refresh the basics. Both Snap and Flatpak are software packaging systems that bundle an application and all its dependencies (libraries, runtimes) into a single package. This means two things:

1. It Just Works: The application will run on any Linux distribution that supports Snap or Flatpak, regardless of whether it’s Fedora, Ubuntu, Manjaro, or openSUSE.
2. Isolation (Sandboxing): The applications run in an isolated environment, separate from the rest of your system. This greatly increases security, as the app doesn’t have default access to your personal files or system settings.

While the goal is the same, the execution is entirely different.

The Core Comparison: Snap vs Flatpak 2025

Though conceptually similar, the formats’ core philosophies and technical choices differ significantly. This has a direct impact on user experience, security, and the future of both platforms.

Philosophy and Centralization: Snapcraft vs Flathub

This is perhaps the biggest ideological difference.

• Snap (Snapcraft): Snaps are tightly controlled by Canonical, the company behind Ubuntu. There is a single, centralized store called the SNAPCRAFT STORE. While you can technically host your own Snap servers, the end-user experience is funneled through this one store. Critically, while the snapd client is open-source, the Snapcraft store backend is proprietary. This bothers many open-source advocates.
• Flatpak (Flathub): Flatpak is decentralized by nature. While FLATHUB has become the de facto central hub for Flatpak apps, anyone can create their own repository. Fedora, for example, offers its own repository alongside Flathub. This openness aligns more closely with the traditional Linux philosophy.

Security Model: AppArmor vs. Portals

Both formats use sandboxing, but they implement it differently.

• Snap: Relies heavily on APPARMOR, a Linux kernel security module developed by Canonical, to enforce security rules. Snaps use “interfaces” that define what they can access (e.g., network, home folder, webcam). These rules are defined at installation.
• Flatpak: Uses a technology called BUBBLEWRAP to create isolated namespaces. The key difference, however, is Portals. When a Flatpak app wants to access something outside its sandbox (like opening a file), it must ask the desktop environment for it via a Portal. This gives the user real-time, granular control over permissions (similar to Android or iOS), which many see as a friendlier and more secure approach.

Startup Speed and Integration

This is where the biggest user complaints have historically been.

• Startup Speed: Snaps have been (and often still are) notorious for slow first-launch times. This is because the system has to mount the compressed application image on the first run. Subsequent launches are faster, but that initial experience can be jarring. Flatpak apps generally have a faster startup time, though they may have larger initial downloads if you don’t have the necessary “runtimes” installed.
• Package size: Another practical difference is package size: Snaps often include all dependencies, making them larger, while Flatpaks can reuse shared runtimes, which reduces duplication.
• Integration: In the early years, both formats struggled with desktop themes, icons, and fonts. By 2025, Flatpak has largely solved this through better portal implementation and theme runtime extensions. Snaps have also improved, but theming issues can still pop up, especially outside of the GNOME desktop that Ubuntu defaults to. By 2025, both systems have improved dramatically, but Flatpak’s closer integration with desktop environments has given it a slight edge in consistency.
• Updates: Snaps feature forced, automatic updates that run in the background. While good for security, this infuriates users who want control over when their apps update. Flatpak updates are managed by the user through their software manager (like GNOME Software or KDE Discover) or via the flatpak update command.

The New Battlegrounds: Where Snap and Flatpak Are Headed in 2025

This is where the Snap vs Flatpak 2025 comparison gets most interesting. Instead of fighting for the exact same market, they seem to be carving out different territories.

Flatpak: The Undisputed King of the Desktop

If you look at most non-Ubuntu distributions, the winner is clear.

• Fedora, Linux Mint, Pop!_OS, and many others default to Flatpak and integrate Flathub out of the box.
• The Steam Deck: The single biggest boost for Flatpak came from Valve. The Steam Deck uses Flatpak (via the Discover store) as its default method for installing desktop applications. This has brought a massive new user base and incentivized developers to publish on Flathub.
• The Focus: Flatpak’s goal remains clear: to be the best way to distribute desktop applications on Linux.

Snap: Looking Beyond the Desktop (AI and Servers)

While Canonical has forced Snap onto Ubuntu desktop users (causing some backlash, e.g., replacing the system Firefox with a Snap), their real strategy became clear in the last year. Snap is no longer just for the desktop.

• Servers and IoT: Snap has long been a strong contender in the embedded (IoT) and server space. Its transactional update nature (which can be safely rolled back if an update fails) is ideal for unattended devices.
• The New Frontier – AI and LLMs: In late October 2025, PHORONIX REPORTED that Canonical has begun using Snap to distribute silicon-optimized AI Large Language Models (LLMs). This is a massive development. Developers can now package AI models, optimized for specific hardware (like Intel or ARM), as a Snap. This allows for easy, one-command installation of complex AI tools (snap install deepseek-r1) while ensuring all dependencies are met.It is worth noting that this is still an emerging use case in 2025, and while Canonical has demonstrated the potential, widespread adoption of AI model distribution via Snap is only beginning.

This Snapcraft vs Flathub comparison clearly shows that Flatpak is winning the desktop, while Snap is building a fortress in the server, IoT, and emerging tech spaces like AI.

Snap vs. Flatpak: Pros & Cons (2025)

Conclusion: Which One Should You Choose?

The answer to Snap vs Flatpak 2025 is no longer “which is better,” but “which is better for you?”

If you are a standard desktop user, especially if you game (Steam Deck) or use a distribution like Fedora or Linux Mint, Flatpak is likely your best choice. It offers a wider selection of desktop apps, better integration, and faster startup times.

If you are an Ubuntu user, you will inevitably use Snaps, as Canonical has built key system components into it.

However, if you are a developer, sysadmin, or someone experimenting with Artificial Intelligence, Snap is becoming an incredibly compelling platform. Its ability to package complex server-side applications and now even AI models gives it a unique advantage in markets Flatpak isn’t even targeting.

The universal package war has ended in a truce: Flatpak has won the desktop, while Snap is carving out the future of server and AI infrastructure.
