10 Best of the Best Linux Apps (2021)

Linux may not be the most popular OS out there, but it does have a fair share of apps. In this post, we’ll explore the best 10 apps for Linux!

10. Darktable

Darktable app

Darktable is an app for processing RAW images taken with a DSLR camera. It is a free program, but don’t let this fool you, Darktable is just as powerful as Adobe Lightroom. I’ve been using Darktable for eight years, and I can say that it is the most impressive Linux app for me.


Gimp app

GIMP is another advanced image manipulation app. It is the best alternative to Adobe Photoshop on Linux. GIMP is not as powerful and intuitive as Photoshop, but it can do the job. For example, I use GIMP for all my image processing for Youtube and this blog.

It’s also worth mentioning that it’s completely free and cross-platform so you can use it on macOS/Windows as well.

8. KColorChooser

KColorChooser app

Many of you are probably familiar with the fact that KDE is my favorite desktop environment. KColorChooser allows you to identify/pick any colour on your KDE desktop just by moving your cursor. If you are a developer/designer or work with colors, then you need to have this app. I use it almost every day!

7. Kdenlive

Kdenlive app

Kdenlive is a powerful, cross-platform video editor. I’ve created every video for my YouTube channel using Kdenlive. While it does not have a glorious past, the future looks bright. Having been using it for a few years now, it’s has improved tremendously with each release.

It’s much more stable and reliable app now. If you need to work with videos on Linux, then look no further than Kdenlive. For all those who had a bad experience in the past, I would recommend giving it a second chance. As of 2021, Kdenlive is a beast!

You can use Kdenlive for basic editing and even for some motion graphics such as lower-third animation.

6. PDFsam

PDFsam app

PDFsam, as the name suggests, is an app for working with PDF files. It’s a very featureful app, and you can perform many operations on PDF files. Split, merge, rotate, extract pages and do so much more!

PDFsam is a freemium app which means that certain features are only available if you purchase it. The basic/free version works for me, and I have covered its features in a separate article.

5. Thunderbird

Thunderbird app

Thunderbird is an open-source email client made by Mozilla Foundation. It is from the same foundation that develops Firefox web browser and other open-source software. For me, Thunderbird is the best email client, and I use it daily.

Contrary to many popular beliefs that its UI is not so great, I like its minimalism and what it offers. Not only does Thunderbird serves as an email client but as an organizer as well with Lighting extension. Thunderbird is open-source and can serve as a replacement to a Calendar app.

4. VirtualBox

VirtualBox app

VirtualBox is an open-source virtualization app developed by Oracle. It’s a must-have for anyone making Linux videos because it’s the easiest way to test any Linux distro or OS for that matter.

You can experiment on Linux in a virtual machine without making these changes to your host OS. For example, if you are installing Arch for the first time and don’t want to mess up your machine!

VirtualBox is also a great option to run Windows and Windows apps inside Linux.

3. KeePassX

KeePassX app

KeePassX is a cross-platform password manager. Having tried many password managers for Linux, KeePassX is the best fit for me. It stores passwords locally, has a minimalistic style which I quite like, especially on KDE. You can learn more about how to use it in our article.

2. Yakuake

Yakuake app

Yakuake is my second favorite app for Linux. It’s probably the one that I use the most as well. Yakuake is a very convenient dropdown terminal. Toggle it with a press of a keyboard shortcut, and it’s ready to take your commands!

These are some of the features that it offers:

  • Split screen
  • Create tabs
  • Configure custom size/animation
  • and so much more!

1. Dolphin

Dolphin app

Dolphin is arguably the best file manager for Linux and my favorite one. It’s very configurable, modern and intuitive to use that it can compete with macOS’s Finder or Windows’s File Manager.

Tabbed interface, custom menu, custom style view for each folder, loads of plugins are only some of the features that Dolphin offers to its users. It’s too advanced to discuss it in this section. Check our article if you want to learn how to leverage the outstanding features of this file manager. I would only like to mention that Dolphin is the only file manager that can have different stye view (icons, list, details) for different folders.

In conjunction with Yakuake, it’s my most used app and deserves the top spot on this list. Exceptional work KDE developers!

Hi Vladimir, thank you for a nice compact but very enjoyable video showing us your favourite apps for Linux. I must say that I do utilise most that you have shown but as always is the case, your tips and illustration of what you do in each app was indeed helpful and I am sure a few of those tips will now find their way in to my daily use of linux.

I am not sure if you have tried the DRILL search app. I downloaded the AppImage and run it and am amazed at its speed and ease of use.

Thanks again for your most enjoyable video and all the best for the soon to be upon us 2022 Christmas/New Year period. Take care as I look forward to your many interesting articles.

Thank you for this list of Linux apps, I look forward to giving many of them a try. I installed Virtual Box last night and I’m trying to decide which distro to try first, it will probably be Ubuntu since I’m just starting off with Linux. I’ve used Gimp with Windows but it’s been quite some time since I’ve used it. Darktable is the one I’m most excited about since I haven’t had a chance to work on my photos in a long time. I’ll definitely be checking out more of your content.


I use ubuntu, but am using Awesome window manager theme by Hikari Knight instead of gnome and removed the app store. I enjoy using celluloid for videos, Cherrytree is a great tree structure note taking application (when I’m not using LibreOffice Writer), youtube-dl is a great downloader for youtube videos and conversion, atom is an excellent app for making and editing computer code files, fd is amazing command line tool to search for files that is better than the default find tool. This is all I can think of for now.
