Browse all categoriesHow to choose virtualization software
Run a second operating system inside your current one — for testing, legacy apps or safe experimentation. With 5 free options on this page, the practical way to narrow it down is by three questions: which platform you run, whether you need the source code to be open, and how much complexity you actually want.
Because everything here is free, you are not risking money by testing two or three — which is usually faster than reading another comparison article. 4 of these are open source, meaning no vendor can revoke your access or move the software behind a paywall later.
Is free virtualization software safe?
Yes — when you get it from the publisher. Nearly every "free software gave me a virus" story traces back to a third-party download portal that wrapped the genuine installer in its own bundler.
That is precisely why this directory hosts no installers at all: every button above opens the software author's own website, so you receive the authentic signed build.
Frequently asked questions
What is the best free virtualization software?
There is no single winner, and any page claiming otherwise is guessing on your behalf. VirtualBox, QEMU, VMware Workstation Pro are the most widely adopted here. VirtualBox run Windows, Linux and other systems in a window.
Do I need to create an account?
Not with us. We have no accounts, no paywall and no download gate. Some publishers may ask you to register on their own site — that is their choice, not ours.
Why don't you show star ratings?
Because we have no honest way to produce them yet. Ratings on a directory are only meaningful if they come from verified real users, and inventing them — as many software listing sites do — would make every other fact on this page untrustworthy too. We publish verifiable attributes instead: developer, licence, platforms and features.
