Top 20 Open-Source Alternatives to Popular Windows Software

Open-Source Alternatives to Popular Windows Software

When you use your computer for work, there are a few apps that are essential to the workload you’re doing. 

Things like the Microsoft Office suite or Adobe Photoshop are always the first to come up because they’re the most popular and arguably the most convenient. 

But because of that, they can also have exorbitant price tags, predatory subscription services, or generally poor practices from the large corporations that own them. That’s why open-source software is so great.

There are plenty of free alternatives to these popular apps, but even then, free apps can be owned by shady companies or change their monetization strategy at any point. 

Some argue that open-source software is the only way to give power back to the community of users and developers. And that’s why we’ve compiled this list of the best open-source alternatives to popular software on Windows.
