Testing Multiple Linux Distributions Is Now Possible Without Even Closing Your Browser, with DistroSea
One of the consequences of GNU/Linux environments being free software is that there is an enormous variety of options to choose from when deciding which distribution to install on our machines.
Until recently, one of the most popular tools for this task was DistroTest, a website that allowed users to emulate various Linux distributions directly in their browser for a first look, free of any security risks.

However, DistroTest has been offline for some time now. Fortunately, when one door closes another opens quickly, and in its place a new alternative has emerged called DistroSea, which offers a very similar user experience.
This means that anyone turning to DistroSea can try out various Linux distributions without having to install any of them on their own machines.

Using DistroSea
Using DistroSea is straightforward: when you visit the site you will find a wide list of popular distributions, such as Alma Linux, Arch Linux, CentOS Stream, Debian, Fedora, Linux Mint, openSUSE, Slackware, Ubuntu… among many others.
And not only can you try one distribution or another — once you select one, you will be able to choose a specific version of it.
Once you have selected the distribution and version, the website will start virtualizing the chosen operating system and, within seconds, a session will open in which users can interact with the distribution.

By default it launches in full-screen mode, but users simply need to press ESC or F11 to return to the normal view.
At the moment, DistroSea offers ‘only’ 39 virtual machines to test. However, its creators plan to add more distributions in the future. They also intend to soon add a server located in Europe or the US, to address the latency issues caused by the current server, which is located in India.
As for how DistroSea works, few details are available at this time. According to a Reddit thread, it appears that most distribution ISO images are downloaded via the quickget script from the Quickemu project, a handy tool for fast and easy emulation. The noVNC libraries are used to render the desktop inside a web page.
How DistroSea Actually Works
DistroSea runs Linux distributions inside a virtual machine that streams directly to your browser via noVNC. You pick a distro from the list, wait about 30-60 seconds for it to boot, and then you get a working desktop you can actually click around in — not just a screenshot tour.
It’s not fast, and it’s definitely not representative of what performance feels like on real hardware. But for answering “what does this desktop environment actually look like to use?” it’s surprisingly useful.
What’s Available and What to Try First
DistroSea has a solid selection — Ubuntu, Fedora, Mint, Debian, Manjaro, openSUSE, and quite a few more niche options. If you’re new to Linux, I’d suggest starting with Linux Mint with the Cinnamon desktop. It’s the most Windows-like experience and gives you a realistic picture of what switching would actually feel like day-to-day.
After that, try Ubuntu with GNOME if you want something more modern, and then maybe Fedora for a comparison. The differences become much clearer when you can click through them yourself rather than reading about them.
The Honest Limitations
Browser-based testing has real ceiling. You can’t install software, the graphics are sluggish compared to native hardware, and anything GPU-intensive won’t reflect reality. It’s also shared infrastructure, so sometimes you’ll get a session that feels slower than others.
Think of it as a 15-minute “does this interest me enough to try it properly?” check, not a substitute for actually booting a live USB. Once you’ve narrowed it down to one or two candidates on DistroSea, the next step is creating a bootable drive with Ventoy or Rufus and testing it properly on your machine.
Frequently Asked Questions
Is DistroSea free to use?
Yes, completely free and no account required. You just go to the website, pick a distribution, and start a session.
How long can a DistroSea session last?
Sessions are typically limited to around 30 minutes. It’s enough to get a real feel for the interface and basic workflows, but not for extended testing.
Can I install software during a DistroSea session?
No. The sessions run in a read-only environment. You can open the package manager and browse what’s available, but installations don’t persist.
What’s a good alternative to DistroSea for more thorough testing?
Creating a live USB with Ventoy is the best next step. It lets you boot the actual distribution on your real hardware and gives a much more accurate performance picture.
Which Linux distribution should I try first on DistroSea?
Linux Mint with Cinnamon is the most recommended starting point for Windows users. It looks familiar, behaves intuitively, and shows you exactly what daily Linux use looks like without overwhelming you.
