Quick Note:

As you may see from the table:

• Open source: Draw from LibreOffice is the most open-source option of all.

5 Best Open-Source Visio Alternatives

LibreOffice Draw: Integrated with Office suite, feature-rich

LibreOffice is a complete package of different applications, ranging from document editors to diagramming tools. The Draw app in the suite is used to draw different types of flowcharts, org charts, network diagrams, etc. With a library of tools and sketching options, it is a robust open-source alternative to Visio.

Draw also has a simple drag-and-drop framework but makes it one step easier with its single-click access option. It offers advanced manipulation with object rotation, a 3D controller, and its signature “Styles and Formatting” box.

Draw.io: User-friendly, online collaborative diagramming

Draw.io is another open-source alternative for Microsoft Visio. Draw.io emphasizes teamwork with its real-time collaboration features. This application stands out in its simplicity and ease of use with a straightforward user interface, allowing easy navigation.

Using Draw.io, you can make UML diagrams, flowcharts, org charts, and whiteboards. Draw.io has gained trust from reputable partners such as Walmart, Tesla, AT&T, and Udemy,  which highlights its authenticity.

The drawing process in Draw.io is simple as it supports layers to handle each component individually. Moreover, it works offline, allowing users to access the app without an internet connection. But, the biggest strength of this app is its security and privacy by restricting its data tracking.

Pencil Project: Specialized in mockups and prototyping

Pencil Project is one of the most user-friendly options to replace Visio. It is a lightweight application with easy installation. Moreover, its open-source GUI makes it accessible to a broader audience. The mobile version of Pencil Project has engaging widgets, such as status bars, icons, and shapes.

This application supports diagram drawing with its built-in shapes and templates. Plus, its colorful yet minimalistic approach makes diagrams more attractive and vibrant. A unique feature of Pencil Project is its inter-page linking, allowing users to link elements in a page.

You can also export your diagrams in different formats using Pencil Project. It allows the creation of desktop, Android, iOS, and web UI with a collection of shapes and graphical elements.

Dia: Coding-based, advanced graph visualization

Dia, or Dia Diagram Editor, is an excellent open-source Visio alternative. It has a neat interface, providing access to all the essential tools and options. The application comes with documentation to train newbies.

However, the biggest strength of Dia is its free-of-cost installation. The app doesn’t ask for in-app purchases or pricing packages. All of its features are available for free, including a collection of shapes.

The shape repository of Dia is also available on its website. There, you will find electrical, HVAC, gradient, optics, racks, electronic, scene mapping, building sites, automata, and other resources. You can install these shapes individually and integrate them into the main Dia software.

The software allows the creation of engineering, database, networking, circuits, computing, lighting, and miscellaneous diagrams.

Graphviz: Simple, efficient, basic diagram creation

Graphviz is yet another best Microsoft Visio alternative open source in our list. It is a visualization app used for creating high-end graphical representations, like network diagrams, database connections, machine learning graphs, and infographics.

It takes convenience to the next level by offering different export formats, like PDF and SVG. Graphviz comes with a variety of graphical elements and tools, but you can also create custom layouts and shapes.

Another plus point of using Graphviz is its support for different platforms. It works well on Windows, Mac, and Linux.

EdrawMax: Free Visio Alternative

Are you unsatisfied with the available alternatives? While the tools in this guide are open-source and free to use, they might have certain limitations, as all free commodities do. Consider giving EdrawMax a try for the following reasons:

With an interface similar to MS Office, you will find it familiar and easy to navigate through the settings and options in the software. The intuitive UI makes it user-friendly to both beginners and pros.

Conclusion

While Microsoft Visio is an excellent app, it is not affordable for everyone. Plus, its steep learning curve might not suit inexperienced users. So, you can always rely on an open-source alternative to meet your diagramming needs. While all the applications in this list are capable, they have their strengths and weaknesses.

Some apps might have expensive pricing, while others lack the robust features available in Microsoft Visio. That is why we recommend using Wondershare EdrawMax. This complete package of an application might be your perfect diagramming partner without being heavy on your pocket.
