Although there are some excellent free alternatives to Visio, most of them have strict limitations in order to encourage users to subscribe to the full version.
That’s why we’ve looked at the best open source alternatives to Visio for Mac that are 100% free for unlimited use on all platforms including for Mac and Windows.
Although you’re simply not going to find anything that can compare with Microsoft Visio for free, we found a number of free open source diagramming apps that allow you to draw flowcharts, network diagrams, process flows and more with no restrictions.
Here then are the best free and open source replacements for MS Visio of 2024.
Although Draw.io (also known as “Diagrams.net”) can’t compare to Visio in terms of features and power, it’s probably the closest thing we’ve used to a free version of Visio.
Draw.io isn’t technically open-source but it is 100% free to use without limitations for as long as you want.
Draw.io imports and exports Visio files and allows you to work offline via desktop app for Windows and macOS. There’s also an extension for Google Chrome which makes it possible to diagram offline in Chrome too.
You can save and upload files from your desktop with Draw.io or you can work directly from Cloud services such as Dropbox, OneDrive and Google Drive.
Draw.io does support exporting to VSDX format although this feature is in beta and doesn’t always work well.
There aren’t many templates either but considering Draw.io is completely free to use for personal use, you really can’t complain.
