OpenOffice has been a popular alternative to Microsoft Office since debuting in 2002, first released by Sun Microsystems. Though the original OpenOffice.org closed its doors in 2011, the app was sold to Apache, where it has since remained free and open-source to the public, allowing users around the world to continue using and developing for the application. And even though the platform has had difficulty attracting developers to the software, OpenOffice remains undoubtedly popular under Apache, averaging over 100,000 downloads per day. Just as users have come to expect from OpenOffice, the platform contains a free replacement for Visio. Called Draw, any ex-Visio user will find themselves right at home with Apache's software.
Draw is a tool that allows you to create and sketch plans, diagrams, and flowcharts to display internally or within a presentation. The app uses a combination of shapes, text, color, and lines to create decent-looking, professional flowcharts. Though the app doesn't quite have the sleekness of newer Visio versions, it's still possible to create some clean diagrams using Draw. The app features a user interface nearly identical to Microsoft Visio, helping any Office converts feel right at home within the platform, and best of all, you'll never have to pay for the ability to use Draw. As with the rest of OpenOffice, the app is free for life, without advertisements or trial limitations. One major drawback: the app isn't web-based, meaning you'll have to download the OpenOffice suite to your computer to use the app. Though this leaves Chrome OS users in the cold, Apache has clients for Mac, Windows, and Linux, making it easy for most users to find their favorite version online.
