Brief: If you are looking for a good Visio viewer in Linux, here are some alternatives to Microsoft Visio that you can use in Linux.

Microsoft Visio is a great tool for creating or generating mission-critical diagrams and vector representations. While it may be a good tool for making floor plans or other kinds of diagrams – it is neither free nor open source.

Moreover, Microsoft Visio is not a standalone product. It comes bundled with Microsoft Office. We have already seen open source alternatives to MS Office in the past. Today we’ll see what tools you can use in place of Visio on Linux.

Best Microsoft Visio alternatives for Linux

Mandatory disclaimer here. The list is not a ranking. The product at number three is not better than the one at number six on the list.

I have also mentioned a couple of non open source Visio software that you can use from the web interface.

1. LibreOffice Draw

LibreOffice Draw module is one of the best open source alternatives to Microsoft Visio. With the help of it, you can either choose to make a quick sketch of an idea or a complex professional floor plan for presentation. Flowcharts, organization charts, network diagrams, brochures, posters, and what not! All that without even requiring to spend a penny.

Good thing is that it comes bundled with LibreOffice which is installed in most Linux distributions by default.

Overview of Key Features:

Style & Formatting tools to make Brochures/Posters

Calc Data Visualization

PDF-File editing capability

Create Photo Albums by manipulating the pictures from Gallery

Flexible Diagramming tools similar to the ones with Microsoft Visio (Smart Connectors, Dimension lines, etc.,)

2. Apache OpenOffice Draw

A lot of people do know about OpenOffice (on which LibreOffice project was initially based on) but they don’t really mention Apache OpenOffice Draw as an alternative to Microsoft Visio. But, for a fact – it is yet another amazing open-source diagramming software tool. Unlike LibreOffice Draw, it does not support editing PDF files but it does offer drawing tools for any type of diagram creation.

Just a caveat here. Use this tool only if you have OpenOffice already on your system. This is because installing OpenOffice is a pain and it is not properly developed anymore.

Overview of Key Features:

3D Controller to create shapes quickly

Create (.swf) flash versions of your work

Style & Formatting tools

Flexible Diagramming tools similar to the ones with Microsoft Visio (Smart Connectors, Dimension lines, etc.,)

3. Dia

Dia is yet another interesting open source tool. It may not seem to be under active development like the other ones mentioned. But, if you were looking for a free and open source alternative to Microsoft Visio for simple and decent diagrams – Dia could be your choice. The only let down of this tool for you could be its user interface. Apart from that, it does let you utilize powerful tools for a complex diagram (but it may not look great – so we recommend it for simpler diagrams).

yED Graph editor is one of the most loved free Microsoft Visio alternative. If you worry about it being a freeware but not an open source project, you can still utilize yED’s live editor via your web browser for free. It is one of the best recommendations if you want to make diagrams quickly with a very easy-to-use interface.

7. Graphviz

Graphviz is slightly different. It is not a drawing tool but a dedicated graph visualization tool. You should definitely utilize this tool if you are into network diagrams which require several designs to represent a node.
