In all honesty, “bloat” is an awkward term that’s subjective, with different meanings, and it’s probably overused. Your experience of bloat will vary hugely depending on your resources and your workflows.
Having said that, a common misunderstanding is that Linux distros are all minimal by default, optimized for lightweight use. While this can be true, the following distros show that it isn’t always.
Ubuntu
The plus-size king of bloat
Ubuntu is probably the most popular, mainstream Linux distro, and it’s one of the most bloated, in general terms.
For a start, Ubuntu uses the GNOME desktop environment by default. This gives it a clean, modern look, but at a cost of resource usage compared to alternatives like Xfce, LXQt, or i3.
Ubuntu also uses Snap as its default package manager. Snap makes it easier to install apps because it bundles everything the app needs, including its dependencies, in a single package. While this system has security benefits and helps avoid issues with library compatibility, it also consumes more disk space. Some users have reported higher RAM usage and slow startup times.
Qubes OS
Demanding hardware requirements
Qubes OS is a distro that picks up the concept of compartmentalization and runs with it. Applications are segmented into virtual machines called qubes and sandboxed to produce a highly secure system.
Once more, however, this robustness comes with a cost: you’ll need a pretty decent machine to run them. Qubes’ base requirements are 6GB RAM and 32GB of free disk space; this doesn’t sound like much, but it’s a lot more than Debian or Puppy Linux. Recommended requirements are also significantly higher: 16GB+ RAM and 128GB+ disk.
Qubes’ templates—which provide shared filesystem access—can help to alleviate bloat, but they can involve a lot of setting up and will be even less familiar to users of more traditional distros.
Garuda Linux
Great for gamers, bad for bloat
Many Linux distros target gamers, with those such as CachyOS and Pop!_OS occupying two of the top five most popular spots on the DistroWatch rankings. Garuda is another such distro, but it’s one that comes with a huge amount of pre-installed software, especially if you opt for the Garuda Dr460nized Gaming edition.
Its Plasma desktop may look good, but it uses heavy visual themes with effects like blurring, and all those built-in applications add plenty of weight to the overall footprint.
As a result, Garuda Dr460nized is really a distro for modern hardware only. Some of its fancier apps, like MangoHUD or the Heroic games launcher, won’t even be of much interest to most gamers, so trimming the fat involves a fair bit of time and effort.
Zorin OS Pro
A massive collection of bundled software
Zorin OS Pro is another full-featured distro, but it targets professionals rather than gamers. This is a distro that actually costs money to buy, but its suite of pre-installed apps may justify the price: video editor, image editor, illustration software, audio workstation, 3d graphics editor, and much more.
All these apps add up, of course, so you’ll need some reasonably beefy hardware to run it. And unless you’re a polymath, you probably won’t be making the most out of every last creativity app that’s bundled in Zorin.
Zorin is also billed as an excellent distro for those migrating from Windows, with a familiar feel and excellent support for Windows apps. But its extensive pre-bundled software and reports of 2GB idle RAM consumption have led some to believe it’s too bloated. Fortunately, a Zorin Lite alternative is available—until 2029, anyway.
Kali Linux Everything
The clue’s in the name…
OK, maybe this is a bit unfair; Kali Linux Everything clearly declares that it’s a bit of a beast up front. Still, I’m including it here to demonstrate just how big some distros can get, and to make a point: bloat is in the eye of the beholder.
Kali Linux is a pretty special distro, designed for security testing and vulnerability analysis. It includes plenty of security tools, which wouldn’t typically come bundled in a Linux distro, and the specific kali-linux-everything metapackage goes even further. This build includes every official Kali Linux tool, so you shouldn’t need to install any additional packages.
Installing the lot will take up 35GB, although recommendations vary between 60 and 100GB for a usable system. In comparison, the fairly bloated Ubuntu requires just 15-20GB for a standard installation.
It’s easy to avoid Linux bloat
“Bloat” is a tricky term to define, since it depends on your own personal usage and its impact varies with your resources. Still, some Linux distros are considerably weightier than others, either purposefully or simply as a result of desktop and tooling choices.
If you’re looking for a lightweight distro, try Mint, Lubuntu, Arch, or Debian.
