After many years of using Synapse as my primary application launcher in Linux, I started encountering more and more issues. Synapse would occasionally freeze, fail to launch automatically at system startup, and sometimes simply stop working during a session. These frustrating experiences led me to search for an alternative, and that’s how I discovered Ulauncher – and I must say, I’m impressed.
What is Ulauncher?
Ulauncher is a fast and modern application launcher for Linux, written in Python using GTK+. It’s an open-source tool that significantly speeds up access to applications, files, and other system functions without having to search through application menus or use a file manager.
Why Switch from Synapse to Ulauncher?
For years, Synapse was my favorite launcher – fast, stable, and functional. Unfortunately, over time it began to cause problems. Sometimes it wouldn’t launch at system startup, requiring manual process restarts through Task Manager. In some cases, it would simply freeze while typing a query. Worse yet, Synapse is currently an abandoned project – the last update was 7 years ago, and the project’s Launchpad page shows virtually no activity. In contrast, Ulauncher is actively developed and supported.
Key Features of Ulauncher
Fuzzy Search
One of Ulauncher’s best features is fuzzy search. You don’t need to know the exact name of an application or file – just type a few first letters, and Ulauncher will find what you’re looking for, even if you make a typo. Moreover, the launcher learns your habits and automatically suggests your most frequently selected options.
Extensions
Ulauncher offers a rich ecosystem of extensions that can be easily installed. Extensions are available for searching emoji, checking weather, speed tests, notes, password managers, and many other functions. Installation is simple – just go to Preferences > extensions > add extension and paste the extension URL.
Shortcuts
You can configure your own shortcuts for searching the internet or running scripts. By default, Ulauncher offers shortcuts such as “g” for Google search, “wiki” for Wikipedia, or “so” for Stack Overflow.
File and Directory Browsing
To quickly browse files and directories, just start typing with “~” or “/”. This is much faster than opening a file manager.
Calculator
Ulauncher allows you to perform calculations directly in the search window, eliminating the need to launch a separate calculator application.
Color Themes
Unlike Synapse’s somewhat outdated look, Ulauncher offers a modern, minimalist interface with customization options. There are 4 built-in themes, as well as the ability to create your own.
Installing Ulauncher
Installation on Ubuntu/Linux Mint is very simple. Just add the PPA repository and install the application:
sudo add-apt-repository ppa:agornostal/ulauncher
sudo apt update
sudo apt install ulauncher
For Arch Linux-based distributions, Ulauncher is available in AUR, and for Fedora in the default repositories.
Configuring Automatic Startup
To have Ulauncher launch automatically at system startup, it’s best to activate the built-in “Launch at Login” option in the application settings. If that doesn’t work, you can add Ulauncher to your system’s startup applications.
How to Use Ulauncher?
By default, to invoke Ulauncher, use the key combination Ctrl + Space. This can be changed in the settings to any other combination. To launch an application, just type the first few letters of its name. For example, typing “fir” will bring up Firefox. To search for files, start with “~” or “/”.
Summary
After switching from Synapse to Ulauncher, I don’t regret the decision. Ulauncher is faster, more stable, and offers more features than its predecessor. Most importantly, it’s actively developed, which gives hope for many years of trouble-free use. If, like me, you’re having problems with Synapse or are simply looking for a modern and functional launcher for your Linux system, I highly recommend trying Ulauncher. It’s a tool that significantly increases productivity and convenience when using the system.
