One of the many ways to speed up Ubuntu system is to use lightweight alternatives of the popular applications.

You have already seen must have Linux applications earlier. Here, let's take a look at the lightweight alternative applications for Ubuntu and other Linux distributions.

Must Have Essential Applications for Desktop Linux Users
Brief: What are the must-have applications for Linux? The answer is subjective, and it depends on what purposes you have for using desktop Linux. But there are still some essential Linux apps that are more likely to be used by most Linux users. Here, we’ve listed the best Linux

Is your Linux system slow? Are the applications taking a long time to open? The best solution for you is to use a lightweight Linux distro.

But it is not always possible to reinstall an operating system, is it?

So if you want to stick to your present Linux distribution, but want improved performance, you should use lightweight alternatives to the applications you are using.

Here, I will put together a list of lightweight alternatives to various popular Linux applications.

Since I am using Ubuntu, I have provided installation instructions for Ubuntu-based Linux distributions. But these applications should work on most other Linux distributions. You have to find a way to install these lightweight Linux tools in your distro.

1. Falkon: Web Browser

Falkon Browser

Falkon browser is a KDE project that aims to provide a clean and lightweight browsing experience.

It was previously known as QupZilla and now uses QtWebEngine as its rendering engine.

As a cherry on top, it comes with a built-in AdBlock extension and offers essential options like keyboard shortcuts, password manager, limited extension support, and a few more things.

Installing Falkon in Linux

Midori is available on Ubuntu via the official repository. Just run the following commands for installing it:

sudo apt install falkon

You can also install it via Flatpak or Snap if you have any other Linux distribution installed.

2. Trojitá: email client

Trojitá is an open-source robust IMAP e-mail client. It is fast and resource-efficient. It utilizes Qt to offer a comforting and yet lightweight experience.

It could be one of the best email clients for Linux if you can live with only IMAP support on your e-mail client. And if that is the case, you may not need to look any further.

Trojitá uses various techniques—on-demand e-mail loading, offline caching, bandwidth-saving mode, etc. — for achieving its impressive performance.

Installing Trojitá in Linux distributions

Unfortunately, it does not offer any pre-built binaries. You will have to compile it from the source by following the official instructions.

3. GDebi: Package Installer

Sometimes you need to quickly install DEB packages. Ubuntu Software Center is a resource-heavy application and using it just for installing .deb files may not be a pleasant experience.

Gdebi is certainly a nifty tool for the same purpose that offers a minimal graphical interface.


GDebi is totally lightweight and does its job flawlessly. You should even make Gdebi the default installer for DEB files.

Installing GDebi in Ubuntu

You can install GDebi on Ubuntu with this simple one-liner:

sudo apt install gdebi

4. App Grid: Software Center

If you use the software center frequently for searching, installing, and managing applications on Ubuntu, App Grid is a must-have application.

It may not have evolved its user experience but it is a fast alternative to the default Ubuntu Software Center.

App Grid

App Grid supports ratings, reviews, and screenshots for applications.

Installing App Grid on Ubuntu based distributions

App Grid has its official PPA for Ubuntu-based distributions. Use the following commands for installing App Grid:

sudo add-apt-repository ppa:appgrid/stable
sudo apt update
sudo apt install appgrid

5. Sayonara: Music Player

Sayonara is an elegant music player with essential audio format support and a lightweight user experience. Undoubtedly, one of the best music players for Linux.

While it offers a fast experience, it also lets you customize a lot of things to tweak your experience.

It uses GStreamer as its audio-backend, which ensures that all the major file formats should work as expected.

Sayonara Music Player for Linux

It supports playlists, library management, and several plugins, including an equalizer, spectrum analyzer, and more.

Installing Sayonara in Linux

You will have to install Sayonara on Ubuntu via PPA using the following commands:

sudo apt-add-repository ppa:lucioc/sayonara
sudo apt-get update
sudo apt-get install sayonara

You also get a Snap package and an AppImage file if you want to install it on any other Linux distribution.

6. Parole Media Player

If you are looking for an alternative to VLC Media Player but on the lighter side of things, Parole Media Player will be a great fit. It

Similar to the Sayonara music player, it also utilizes the GStreamer framework to ensure the best compatibility with file formats and codecs.

Distributions like Zorin OS Lite include Parole Media Player out of the box.

It is primarily tailored for Xfce desktop environments but works on other desktops as well.

Installing Parole in Linux

For Ubuntu-based distros, you should find it in the default repository. So, all you need to do is enter the following command in the terminal:

7. Thunar: File Manager

Thunar file manager is yet another app originally tailored for the Xfce desktop environment but can be used anywhere else.

You should find all the essential features when compared to other file manager applications like Nemo on Linux Mint.

The user interface is simple and offers a side panel, which you cannot hide (I couldn’t find the option to). It may not offer bookmarking feature, but it provides a fast and useful experience.

Installing Thunar on Linux distributions

Installing Thunar on Ubuntu-based distros will just take one simple command:

Installing Mousepad in Linux

For installing Mousepad, use the following command in the terminal:

9. GNOME Office: Office Suite

Many of us need to use office applications quite often.

Generally, most office applications take up more storage space and are resource-hungry.

Gnome Office is quite the opposite in that respect. Gnome Office is technically not a complete office suite but it is composed of different standalone applications and among them, AbiWord & Gnumeric stands out.

AbiWord is the word processor. It is lightweight and faster than other alternatives. But that comes at a cost—you might miss some features like macros, grammar checking, etc. It’s not perfect but it works.


Gnumeric is the spreadsheet editor. Just like AbiWord, Gnumeric is also light on resources and provides accurate calculations. If you are looking for a simple and lightweight spreadsheet editor, Gnumeric has got you covered.


While these two are the key highlights of the collection, you can find the full list of applications in the official Gnome Office wiki.

Installing AbiWord & Gnumeric in Linux

All the tools that are involved with the office suite should be available in the default repositories for most Linux distros. For Ubuntu-based distros, you can type in the following command to install Abiword and Gnumeric:
