Comparing Flatpak and Snapcraft: Pros, Cons, and Use Cases

With the rise of containerization technologies, software packaging, and distribution have also seen major advancements in the past few years. Flatpak and Snapcraft are two of the most popular container-based package management systems that aim to make software installation and distribution more accessible, reliable, and secure. This article will explore the key differences between Flatpak and Snapcraft, their pros and cons, and which one might better fit your use case.

What is Flatpak?

Flatpak is a package management system developed by Red Hat that enables users to install, run, and manage applications in a sandboxed environment. Unlike traditional package managers, Flatpak uses containerization technology to isolate the applications from the underlying operating system, libraries, and dependencies, making them more secure and portable across different Linux distributions.

Flatpak packages are called “runtimes” and “apps.” Runtimes are a collection of system libraries and dependencies required by the applications, while apps are the basic software packages that users can install and run on their systems. Flatpak relies on the Flatpak runtime to provide a standardized environment for the applications, ensuring that they work consistently across different distributions.

What is Snapcraft?

Snapcraft, on the other hand, is a package management system developed by Canonical, the company behind Ubuntu. Like Flatpak, Snapcraft uses containerization technology to package and distribute software in a portable and secure manner. Snap packages contain all the necessary libraries, dependencies, and system resources to run the software, making them self-contained and isolated from the underlying system.

Snapcraft packages are distributed through the Snap Store, an app store-like interface allowing users to discover, download, and install Snap packages on their systems. Snap packages are also designed to work seamlessly across different Linux distributions, making them popular for developers who want to distribute their software to a broader audience.

Flatpak vs. Snapcraft: Pros and Cons

Now that we have a basic understanding of Flatpak and Snapcraft, let’s compare the two based on their pros and cons.

Flatpak Pros:

  • It supports multiple runtimes, allowing developers to choose the runtime that best fits their application’s needs.
  • Provides a standardized environment for applications, ensuring that they work consistently across different distributions.
  • Allows users to install and run applications without root access, making it a more secure option.
  • Offers support for OSTree, a technology that allows users to roll back to previous versions of an application or runtime in case of issues or conflicts.

Flatpak Cons:

  • It can be slower to start up and run applications due to the containerization overhead.
  • Requires a separate runtime for each application, which can lead to increased disk space usage.
  • It can be challenging for developers to package their applications due to the strict sandboxing requirements.
  • The Flatpak ecosystem is relatively new, so not all Linux distributions support it out of the box.

Snapcraft Pros:

  • Offers a user-friendly app store interface for discovering, installing, and updating snap packages.
  • Provides a self-contained and isolated environment for applications, ensuring that they work consistently across different distributions.
  • Allows users to roll back to the previous application or snap package versions in case of issues or conflicts.
  • It offers various system interfaces and APIs that developers can use to integrate their applications with the underlying system.

Snapcraft Cons:

  • Limited runtime support means that developers have to use the default snap runtime provided by Canonical.
  • It can be slower to start up and run applications due to the containerization overhead.
  • Requires additional disk space to store the snap packages, which can be a concern for systems with limited storage.
  • Some system interfaces and APIs are only available to snap packages installed with the “classic” confinement, which may not be suitable for all use cases.

Which One is Better: Flatpak or Snapcraft?

Deciding which is better between Flatpak and Snapcraft depends on your use case and requirements. Both Flatpak and Snapcraft have their pros and cons, so it’s essential to evaluate them based on your needs.

If you’re a developer who wants to package and distribute your applications across different Linux distributions, Snapcraft might be a better choice. Snapcraft’s app store-like interface and wide range of system interfaces and APIs make it easier for developers to reach a broader audience and integrate their applications with the underlying system.

On the other hand, if you’re a user who wants a more secure and standardized environment for running applications, Flatpak might be a better choice. Flatpak’s support for multiple runtimes and sandboxing requirements ensures that applications work consistently and securely across different distributions.

Conclusion

Flatpak and Snapcraft are two popular container-based package management systems that offer a more secure, reliable, and portable way to install and manage applications on Linux systems. While both have pros and cons, the choice depends on your use case and requirements. As a developer, Snapcraft’s app store-like interface and system interfaces might be more appealing. At the same time, Flatpak’s standardized environment and sandboxing requirements might suit users who want a more secure system.
