50 Must-Have Open Source Apps for Your Home Office

Datamation content and product recommendations are editorially independent. We may make money when you click on links to our partners. Learn More.

These days, more and more people work at home at least part of the time. According to the U.S. Small Business Administration, more than half of the 29.6 million small businesses in the country are home-based.

If you add to those figures the number of people who telecommute to their jobs part of the time, the Telework Research Network estimates that between 20 to 30 million people work from home at least once a week. And WorldatWork claims that approximately 44 million Americans work at home at least one day a year.

Whether they work for themselves, a small business or a large multinational corporation, all of these workers need good software for their home offices. And many of these people who work at home don’t have a lot of money to spend on that software — especially if they work for themselves.

With those workers in mind, we’ve created a list of open source applications that are the most helpful for home offices. Unlike many of our other Datamation lists, we’ve kept the number of applications in each category small—usually just the one or two top apps in each category. Nearly all of this software will run on Windows, and these are some of the most mature and user-friendly open source applications available. If you’re reasonably tech-savvy, you should be able to set up and use any of these apps.

Also, recognizing that home office computers get used for more than just work, we’ve included a mix of business software, utilities, and “fun” apps for those times when you need a break.

As always, if you’d like to recommend another open source app that we’ve missed, feel free to add a comment below.
