Must Have Essential Applications for Desktop Linux Users

What are the must-have applications for Linux? The answer is subjective. Here, we’ve listed some of the best options.
Warp Terminal

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!

Non-FOSS Warning! Some of the applications mentioned here are not open source. They have been included in the context of Linux usage.

Image Editors

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.


Audio Editors

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.

Screen Recording and Streaming Tools

screen recorders for linux

Are you a Blogger, YouTuber, or work in similar industries? Here are a few tools for you.

1. Kazam 📷

If you’ve been following us, you might have already read about the best screen recorders available for Linux.

Kazam is the simplest solution among them. It lets you record your screen and includes several essential features like giving you the ability to select the area/window, hiding/showing the cursor, and enabling the sound from your mic/speaker.

For installation instructions, its GitHub page would be your best bet.

3. Flameshot 📸

Flameshot is yet one of the nicest options to take screenshots and annotate them.

You can even directly upload your images to Imgur without needing to save them on your PC. Regardless of what Linux distro you use, you could find it handy.

We’ve discussed multiple ways to take screenshots in Linux, and using Ksnip is one of them.

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

gaming apps linux

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.

📋
You can always try Heroic Games Launcher, Bottles, or Lutris game clients if you want to use Epic Games Store on Linux.

1. Timeshift 📁☁️

Yes, we often keep a backup of our files. But what about the driver updates and configuration changes that you perform? What if these break your entire system?

In such a case, Timeshift will help you take a backup (or a snapshot) of your entire OS along with all its configurations. You can easily restore it when something goes wrong. We have a guide on how to use Timeshift on Linux as well.

Code and Text Editors

code editors linux

1. VS Code 👨‍💻

Even though we’re Linux users, I’ve noticed that many people like the Visual Studio Code editor. It includes a smart feature to autocomplete what you write based on variable type or function definition. It’s highly recommended if you’re working with Git, because the relevant commands are built-in. And as you start exploring, you’ll discover so much more to it.

1. Slack 💬

Even at It’s FOSS, we used Slack before moving to other chat platforms for team communication. This is not an open-source solution.

Slack on Linux is available for free, and you can opt to upgrade it to the premium version for more features. You won’t be needing a premium plan unless you’re an enterprise user with many users to manage. Free or premium, it’s an essential addition.

You can also look for open-source Slack alternatives if you don’t like it.
