For VMware vs VirtualBox on a desktop lab, both are good, free type 2 apps. VMware Workstation (Windows, Linux) and Fusion (Mac) are polished and, as of October 2026, free for personal and commercial use (verify on Broadcom's site). VirtualBox is open source and runs on all three platforms. Proxmox is a server platform, not a desktop app, but you can run it inside either one to learn it.
Who this is for: you want to run virtual machines on the computer you already own, and you need to pick one tool to start.
What a desktop lab is
A desktop lab is a set of virtual machines on your everyday laptop or desktop. You install a hypervisor app, create VMs, and break things without risk to your main system. It is the cheapest way to start a home lab, because you need no extra hardware.
VMware Workstation, VMware Fusion and VirtualBox are type 2 hypervisors. They run as apps on top of your normal OS. Proxmox VE is a type 1 hypervisor. It installs on bare metal and becomes the OS. If those terms are new, read type 1 vs type 2 hypervisors explained first. The difference shapes everything below.
VMware Workstation and Fusion
VMware makes two desktop products. Workstation Pro runs on Windows and Linux hosts. Fusion Pro runs on macOS. Broadcom now owns VMware.
License
In May 2024, Broadcom dropped the price of Workstation Pro and Fusion Pro to zero for home users. On 11 November 2024, it made them free for all use: personal, commercial and educational. You need no license key. Broadcom sells no support for these free versions. As of October 2026, verify the current license, download steps and any commercial-use rules on Broadcom's site. Start from the Broadcom TechDocs portal and search for Workstation or Fusion. Do not rely on an old blog post (this one included) for license terms.
Strengths
- Mature, stable and well documented.
- Good graphics support for desktop guests.
- Snapshots, clones and virtual networks that are easy to set up.
- A familiar path if you work with VMware at your job.
Limits
- Closed source. You depend on Broadcom's choices about pricing and downloads.
- The download process needs an account on Broadcom's portal. Some users find it confusing.
- Fusion on Apple Silicon Macs runs ARM guests. You need ARM builds of Windows or Linux, not the usual x86 ISOs. Check the current docs for what is supported.
Oracle VirtualBox
VirtualBox is Oracle's free hypervisor app. It runs on Windows, macOS and Linux hosts. The base package is open source under the GPL.
License
The core VirtualBox package is free for any use. The Extension Pack is different. It adds features such as some USB and remote display support, and it has its own license (the PUEL). That license has limits on use in organizations. As of October 2026, read the license terms on the VirtualBox downloads page before you install the Extension Pack at work.
Strengths
- Free and open source for the core package.
- One tool on all three desktop platforms.
- Large community and many guides.
- Works well with Vagrant and other automation tools.
Limits
- Graphics and desktop feel can be less smooth than VMware for some guests.
- On Windows, VirtualBox can clash with Hyper-V features (WSL2, Windows Sandbox, some security settings). It can run on top of the Windows hypervisor, but performance may drop. Check the VirtualBox manual for the current guidance.
- Apple Silicon host support is newer than the x86 version. Check the current docs for which guests work.
Proxmox VE: not a desktop tool, but worth learning
Proxmox VE is a server platform. It is based on Debian Linux, uses KVM for VMs and LXC for containers, and you manage it from a web browser. You do not install it as an app on Windows or macOS. You install it on its own machine. The guide to what Proxmox VE is covers the details.
So why is it in this comparison? Because many people start with a desktop app, then move to Proxmox on a spare PC or mini PC. You can try Proxmox first inside VMware or VirtualBox. This is called nested virtualization. A VM runs Proxmox, and Proxmox runs its own VMs inside it.
How to run Proxmox nested
- Check that your CPU supports hardware virtualization (Intel VT-x or AMD-V). Turn it on in the BIOS or UEFI.
- Download the Proxmox VE ISO from the official site.
- Create a VM in VMware or VirtualBox with at least two CPU cores and enough memory for Proxmox plus one small guest.
- Turn on nested virtualization in the VM settings. VMware calls it "Virtualize Intel VT-x/EPT or AMD-V/RVI". VirtualBox calls it "Enable Nested VT-x/AMD-V".
- Boot the ISO and install Proxmox. Then open its web interface from your host browser.
Menu names change between versions. If a setting is missing, check the docs for your version. Nested guests run slower than guests on bare metal. Use nesting to learn, not to host services you rely on.
Apple Silicon Macs are different. Proxmox VE is built for x86 (Intel and AMD) processors. An M-series Mac uses an ARM processor, so it cannot run Proxmox with hardware virtualization. You can only run it under full x86 emulation, which is very slow. On an Apple Silicon Mac, learn Proxmox on a spare x86 PC or a rented server instead.
For install steps, system requirements and the current release, use the Proxmox VE documentation. As of October 2026, Proxmox VE is free and open source, with an optional paid subscription for the enterprise repository. Verify the current terms on the Proxmox site.
VMware vs VirtualBox vs Proxmox: comparison table
This table reflects the products as of October 2026. Verify every row on the vendor page before you decide. License terms in particular change often.
| Factor | VMware Workstation / Fusion | VirtualBox | Proxmox VE |
|---|---|---|---|
| Hypervisor type | Type 2 (app on your OS) | Type 2 (app on your OS) | Type 1 (bare metal) |
| Windows host | Yes (Workstation) | Yes | No (runs nested only) |
| macOS host | Yes (Fusion) | Yes (check Apple Silicon support) | Intel Macs: nested only. Apple Silicon: emulation only, very slow |
| Linux host | Yes (Workstation) | Yes | It is the host OS |
| Source | Closed | Open (core), Extension Pack separate | Open source |
| Cost | Free for all use, no paid support (verify) | Free core (verify Extension Pack terms) | Free, optional paid subscription (verify) |
| Containers | No | No | Yes (LXC) |
| Web management | No | No | Yes |
| Best for | Polished desktop VMs, VMware skills | Free cross-platform lab | A dedicated home server |
What your computer needs
All three tools need a 64-bit CPU with hardware virtualization turned on. Most desktop and laptop CPUs from the last decade have it. Check your BIOS or UEFI if VMs refuse to start.
Memory is the real limit. Your host OS needs its share, and each VM needs its own. Plan for your host plus every VM you want to run at the same time. A fast SSD also helps, since several VMs reading from one slow disk feel sluggish. I do not quote exact numbers here, because they depend on the guests you run. Check each guest OS for its own minimum.
Which one should you pick?
Start from the computer you have and the goal you want.
- You are on Windows or Linux and want the smoothest desktop VMs. Try VMware Workstation Pro, after you confirm the current license.
- You want free, open source and the same tool everywhere. Pick VirtualBox.
- You are on an Apple Silicon Mac. Fusion is the more mature choice for ARM guests today. Check VirtualBox's current Mac support before you rule it out.
- You use Windows Pro and already need Hyper-V. Consider Microsoft Hyper-V itself. It avoids the clash with other hypervisors.
- You want a server that runs 24/7. Skip the desktop apps. Put Proxmox on a spare PC. The guide to home server setup walks through the hardware.
My view: install one desktop app, then nest Proxmox inside it for a weekend. If you like Proxmox, move it to real hardware. If you work in a VMware shop, the Proxmox vs VMware comparison covers the server side.
What to watch for
- Two hypervisors on one host. Running VMware and VirtualBox at the same time can fail or run slowly. Close one before you start the other.
- Hyper-V features on Windows. WSL2, Docker Desktop and Core Isolation can turn on the Windows hypervisor. Your desktop app then runs on top of it, often slower.
- Too little memory. Every VM takes RAM from your host. Leave enough for your own OS, or the whole machine slows down.
- Laptop sleep. Close or suspend VMs before your laptop sleeps. A VM caught mid-write can corrupt its disk.
- Old license advice. VMware and VirtualBox license terms have changed. Always read the vendor page, not a forum post.
FAQ
Is VMware Workstation free?
Yes, for personal and commercial use since November 2024. Verify on Broadcom's site. As of October 2026, Workstation Pro and Fusion Pro need no license key, and Broadcom sells no support for them. Terms have changed before and may change again.
Is VirtualBox better than VMware?
Neither is better for everyone. VirtualBox is open source and runs on all three desktop platforms. VMware is often smoother for desktop guests and matches skills used at work.
Can I run Proxmox in VirtualBox?
Yes, on an x86 host (Intel or AMD). Turn on nested VT-x/AMD-V in the VM settings and install Proxmox from its ISO. Guests inside the nested Proxmox run slower, so use it for learning only. On an Apple Silicon Mac, Proxmox runs only under x86 emulation, which is too slow for real use.
Can VMware and VirtualBox run on the same computer?
You can install both. Running VMs in both at the same time may fail or run slowly. Close one app before you start VMs in the other.
Is the VirtualBox Extension Pack free?
It is free for personal and educational use, under a different license (the PUEL) from the core package. Commercial use needs a paid license. Since version 7.1, there is no free 30-day evaluation for business use. As of October 2026, read the current terms on the VirtualBox site.
What is the best desktop virtualization software for a beginner?
VirtualBox is a safe first step, since it is free and runs everywhere. VMware Workstation or Fusion is a good choice if you want more polish. On an x86 PC, either one can host a nested Proxmox when you are ready.
