Are you bored in windows?
The best and free alternative for windows is linux.
There are large number of linux distros in internet.
I’m personally suggest linux mint and zorin os for windows alternative.
In this blog I tried to show free and open source linux essential apps.
In addition, we’ve categorized the apps as well to get you started!
Image Editors
GIMP

Allowing plugins that extend its functionality while being an open source solution is impressive. It offers almost every type of tool you will ever require manipulating an image, scale it, crop it, or simply add a layer to it. You can install it from your AppCenter or Software Center, or visit to GIMP’S website download it.
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 most of the 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.
Audio Editors
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. It supports plugins to extend its functionality. If you’re wondering: it’s open-source software and available for free. You can install it directly from the App Center or Software Center, or from the official download page.
Email Clients
Thunderbird
A simple and free email client developed by Mozilla. You may find it pre-installed on some Linux distributions – if not, you can easily install it using your Software Center or App Center. You can also download it from their website and then install it.
It offers most of the features you need – however, the UI may be the only downside for some.
Personal Communication

Signal is a popular open-source instant messaging app as one of the alternatives for whatsapp
We also have a guide to help you install Signal in Linux to get started.
Streaming Tools
Blogger, YouTuber or work in similar industries? Here are a few tools for you.
OBS
Open Broadcaster Software is a pretty popular and robust screen recorder app often used by streamers.
You can heavily customize it, add your own template, etc. So there’s a lot of things you can do once you start exploring it. OBS is suitable for both personal and professional users – it’s not the easiest but it’s really useful.
Flameshot
Flameshot is for taking screenshots and annotating them. Heck, you can even directly upload your images to Imgur without needing to save them on your PC. I use this no matter what Linux distro I install — it’s so easy and flexible, you might want to install it too.
Steam
Yes, Steam is a proprietary client or marketplace for purchasing/installing/managing your Linux games. But it’s the best client out there, also offering a huge library to choose from. You’ll find both free and paid options, so browse through them. To install it, you can download the .deb file from its official download page or find the installer on AppCenter or Software Center.
Media Players
Audacious
Audacious is a simple music player that is low on resources while being an open-source solution. You can customize the interface to give it a different look. To add songs, just drag and drop the folder you want. You can either install it from the Software Center or visit the official download page.
Go on, get started!
VLC
I’ve tried a lot of video players on my Windows machine and on Linux systems as well – but I keep going back to VLC pretty much every time. VLC is a simple media player that’s open-source and free as well. It supports almost every type of file format. You can download it from their website or find it on your Software Center.
Media Server Software
Kodi
Kodi is definitely one of the best media server programs available for Linux. Many of the other best media server tools are based on Kodi as well.
Video Editors
Kdenlive
Kdenlive is one of the best professional video editing available for Linux. It’s an open-source solution and also offers support for dual monitors. It includes most of the necessary features like basic transition effects, layout customization, multi-track editing, and so on.
PDF Editing Tools
PDF Studio
PDF Studio is an amazing PDF editor by Qoppa software. It’s not an open source offering – in fact, it’s a paid solution for users looking to edit PDF files. It offers a bunch of features (annotate, edit, optimize, sign, watermark, etc.) for manipulating PDF files easily.
Code and Text Editors
VS Code
Even though we’re Linux users, I’ve noticed that a lot of 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 that there’s so much more to it.
Lyx
An open-source editor with a lot of features. If you’re writing scientific documents or a thesis, this can come in handy with its formula editor to make things easier. You can download it right from the AppCenter or Software Center. More information can be found on their website.
Virtualization Apps
Oracle VM VirtualBox
VirtualBox is an amazing free and open-source virtualization solution for those who want to try different distros (or experiment with stuff) without affecting your host system. There are numerous uses for it – go explore!
Authenticators
Authy
Almost everyone uses 2-factor authentication to secure their online accounts. But usually, you need your smartphone along with an authentication app for the codes, right? Fret not, with Authy, an alternative to Google Authenticator, you’ll be able to sync 2FA codes across devices without the risk of losing them. It is available for Android, iOS, Linux, Windows, and macOS as well.
