If you've ever tried running Windows apps on Linux, you know how challenging it can be. I've been using Wine or WinApps for it, but the results are often hit or miss, and sometimes it raises compatibility issues as well. Similarly, running a whole virtual machine comes with its own challenges, especially on not-so-high-end devices. These often feel like workarounds rather than actual solutions.
While I love running Linux and have recently been doing most of my tasks on it, as a long-time Windows user, there are a few Windows-only apps that I simply cannot function without. That's when I began searching for a more effective and manageable way to bridge the gap between my Linux system and Windows applications.
On my hunt, I discovered WinBoat — a free, open-source app that surprised me with its ease of installation and use.
What is WinBoat?
A quick overview
WinBoat is a lightweight, containerized tool that makes it easy to run Windows environments on Linux using Docker. It's like a portable Windows sandbox, but unlike traditional VMs, it doesn't bloat my system and, surprisingly, isn't resource-hungry.
To put it simply, the Windows OS runs as a VM inside a Docker container, and it uses WinBoat Guest Server to fetch the necessary data from Windows. You can access it via FreeRDP (or a browser-based interface). This makes it flexible, efficient, and user-friendly.
The best part of WinBoat is that it's free and open-source. There's no paywall, and the whole project is community-driven.
How I set it up
From installing to running Windows apps in minutes
Setting up WinBoat was far smoother than I expected. I set it up on my Ubuntu 24 machine, but you can install it on anything that supports Docker.
I made sure that I had these prerequisites fulfilled before attempting the installation process:
- RAM: At least 4GB free for WinBoat only (I tested it on 2GB and 3GB RAM, and it went horribly)
- CPU: At least 2 CPU threads
- Storage: At least 32GB (I allotted 40GB)
- Virtualization enabled
- Docker installed
- Docker Compose v2 installed
- FreeRDP
- iptables and iptable_net modules loaded
After meeting the prerequisites, here are the steps I took:
- I downloaded the latest release of WinBoat from the official GitHub page. For Ubuntu, I downloaded the ".deb" version.
- After downloading and installing it, the process was straightforward. I launched WinBoat using the terminal.
- Then I created the Windows instance, and the GUI guided me in allotting RAM, CPU, and disk space. There's also an option to pick a custom ISO, but I let WinBoat handle it automatically.
- Within 30–40 minutes, WinBoat set up everything and was ready to run Windows apps.
That was it. No registry tweaks, no driver installation, and nothing complex. The Windows container was ready to run whatever apps I required. Compared to setting up a traditional virtual machine, this was much less of a headache overall.
Features that make WinBoat stand out
Why I prefer it over other approaches
What makes WinBoat different from other ways is how it works. If you want a proper balance between flexibility and simplicity, it's a better approach. Unlike traditional VMs, you don't have to manage full virtual disks or manually install operating systems. Unlike Wine, it doesn't raise unexpected compatibility issues. There are certain things that set it apart.
First, WinBoat is container-based, which means you don't need to install Windows from scratch — the image is prebuilt and ready to use. And despite its simplicity, it still provides a complete Windows environment in which I can run anything, from older apps to modern ones, without any compatibility issues.
All applications I run are in an isolated container, so my Linux system is untouched and there's almost no chance of system failure (until, of course, you allocate your maximum RAM to WinBoat). Furthermore, I can allocate RAM, CPU threads, and storage depending on what I require from the Windows environment. So, let's say I just want to run the native Windows Notepad app; I can set the minimum hardware configuration for it.
Since the containers are persistent, I can save and resume sessions like a lightweight VM snapshot. Also, apart from the default Windows apps, I can also side-load third-party Windows apps using WinBoat. Overall, for daily use, the WinBoat approach is best for running Windows apps.
Things to keep in mind
A few limitations worth noting
Of course, like any other software, WinBoat also has limitations. For starters, you need to be comfortable with Docker to use it. According to its GitHub page, Docker Desktop isn't supported, so the setup is only available through the terminal. Frankly, it's not overly complex, but you need to run a few commands on the CLI.
Performance is another consideration. WinBoat is pretty efficient, but it still runs a complete Windows environment, so you'll still require decent hardware. The app requires at least 4GB of RAM, and you cannot allocate more than half of your total system RAM, so you need to have more than 8GB of RAM. If you intend to use heavy Windows applications, you need to have the corresponding hardware components.
If you plan to run modern, GPU-intensive games, WinBoat is not the right tool for the job. It's not optimized for running games, and you might run into trouble.
Overall, it's not for everyone, but if you are a Linux user who needs a reliable and clean way to run Windows apps for testing or simply because they're not natively available on Linux, it's absolutely worth trying.
