What is Snap and Why Use It?
I don’t know if you know or not but Snap is a universal package format developed by Canonical, the maker of Ubuntu. The main benefit?

Whether you’re using Ubuntu, Fedora, or Arch, Snap ensures that the app will run smoothly without compatibility issues.
So here is why you might want to use Snap:
- Automatic Updates: Snap packages automatically update in the background when the system is turned on and connected to the Internet. No more worrying about whether you’re running the latest version.
- Enhanced Security: Snap applications run in a sandbox, meaning they are isolated from your system. This provides an extra layer of security. Isn’t it great?
- Cross-Platform Compatibility: Snap is not just for Ubuntu; it works across multiple Linux distributions, making it versatile and more useful.

While Snap is convenient, it’s not the only option for installing applications on Ubuntu. Here are some alternatives:
- APT (Advanced Package Tool): APT is Ubuntu’s default package manager and works for installing software from the official repositories. While it doesn’t bundle dependencies like Snap, it’s lighter and faster. When it comes to install packages from Ubuntu’s official repo then APT is great. But yes, it’s not necessary that you will find all the apps in the official repo.
- Flatpak: Like Snap, Flatpak is a universal package format that works across different Linux distributions. It’s known for sandboxing apps and providing the latest versions without needing root access.
- AppImage: AppImage is a portable package format. You can download an AppImage file, make it executable, and run it without needing to install it. It’s a great choice for users who want a completely self-contained app.
Each of these alternatives has its own pros and cons, but Snap stands out for its ease of use and security features.
