In the world of Linux, there are alternatives to everything. Choosing a distro? There are dozens of them. Trying to find a decent music player? Plenty of alternatives there too.
But not all of them are built with the same thing in mind – some of them might target minimalism, while others might offer tons of features. Finding the right application for your needs can be quite a confusing and boring task.
Let’s make it a bit easier 😉
⭐ Essential applications for Linux users
I have put together a list of the essential Linux applications that I prefer to use in different categories.
I’m not saying that they are the best, but I’ve tried many applications in each category and these are the ones I liked the most. So, you are more than welcome to mention your favorite applications in the comments section, too.
In addition, we’ve categorized the apps as well to get you started!
We’ve already discussed some of the best photo applications for Linux. Here we shall mention two essential tools for every user.
1. GIMP 🖌️🎨
GIMP is the holy grail of image editors for casual users and professionals. It offers almost every type of tool you will ever require manipulating an image, scaling it, cropping it, or simply adding a layer to it.
Allowing plugins that extend its functionality while being an open-source solution is impressive.
You can install it from your Software Center or follow our GIMP installation guide.
2. Inkscape 🖋️
One of the best Linux tools for digital artists, Inkscape is certainly an impressive image editor as well.
Unlike GIMP, Inkscape comes pre-installed on many major Linux distros. It offers a bunch of drawing tools and vector graphics editing capabilities, making it a powerful choice for manipulating images as well.
3. Conjure ➰
If you are looking for a tool to help you with quick tasks like Blur, Emboss, Sharpen, etc, Conjure can help you transform images.
It is a fairly new GUI tool as a front end to ImageMagick.
1. Audacity 🎧
We’ve mentioned several audio editors in the past, but Audacity is the most popular tool for basic editing tasks. You can try to experiment and pull off something interesting as well. For instance, reducing noise from your recording.
It supports plugins to extend its functionality. If you’re wondering: it is an open-source software and available for free. You can install it directly from the Software Center, or explore other options on its official download page.

LMMS is a free and open-source Digital Audio Workstation (DAW) available cross-platform. Undoubtedly, it is one of the best DAWs for Linux.
It is a feature-rich alternative to premium audio editors (or DAWs) for creating, editing, and recording music. If you have a MIDI device, you can just plug it into your machine and get started with LMMS. It also supports VST plugins, to say the least.

Evolution is the default mail app for GNOME desktop users, and it is quickly replacing Thunderbird as a pre-installed mail client on numerous Linux distributions.
It offers a nice user interface and also supports Microsoft Exchange using an extension.
You can check out its GNOME wiki page to find links to Flatpak and other installation options.

4. Ksnip ✂️
A simple Qt-based cross-platform screenshot tool that offers more annotation features.
We’ve discussed multiple ways to take screenshots in Linux, and using Ksnip is one of them.
It’s fairly new, and not the most popular screenshot tool out there, but it works as expected. Refer to its GitHub page for information on installation and more.
System Optimizers/Task Managers
1. Stacer ⚙️
Stacer is my favorite system optimizer and task manager on Linux, with a beautiful user interface.

2. htop 🖥️
You probably know about the default “top” CLI tool to monitor processes in your system. It is still useful – but not the best out there.
So if you’re looking for a better command-line based tool, htop is the perfect replacement. You no longer need to type in the process number to kill it, just navigate to it and end it. It is way easier and faster than the traditional top CLI tool.
You can also take a look at our list of top alternatives to find more utilities for system monitoring.
Apps for Gamers
While I recommend going through our gaming guide to get better insights on what you need to game on Linux. These are the absolute best apps to have:
1. Steam 🎮
Yes, Steam is a proprietary client or marketplace to purchase/install/manage your Linux games.
However, it is the best game client with a massive library of free and paid games to offer (both native Linux games and Windows exclusives).
To install it, you can download the .deb file from its official download page or find the installer on Software Center. We also have a quick Steam installation guide for help.
2. Discord 🎮🕹️
Without a second thought, if you’re a gamer, you have to install this one right away. Do note that it’s not an open-source application.
Yes, there are alternatives to it. But nothing beats Discord when it comes to the ability to manage a server room where fellow gamers can interact and communicate on voice channels in-game.
You can easily install Discord on Linux.

Backup is one of the essential parts of not only Linux, but any operating system. Here are two options for you.
1. Timeshift 📁☁️
