10 Best Diagram Software Tools in 2025 (Free & Paid)

There might be some unicorns out there who can learn just by hearing about something. But most of us are visual learners. We need to see something in front of us to fully get it.

When you take steps to represent ideas and processes visually—by mind mapping, charting, and diagramming—you can get your whole team on board. And when some of your processes get complicated, a diagram can provide a quick reference that your team will actually use (which is more than we can say for that hundred-page handbook). 📔

With the right diagram software, you can whip up a visual that makes your whole team go “Ahhhh, I get it now.” And you can collaborate, brainstorm, edit, and re-org with ease.

Find out what to look for in diagramming software, and discover the 10 best tools you can get right now.

What Should You Look for in Diagram Software?

The best diagram tools have a few things in common. You’ll see these things come up again and again in our descriptions of the software featured below. And that’s because some features are must-have, can’t-live-without essentials.

If a diagramming tool doesn’t do these three things, it’s a no for us:

  • Templates : Diagram templates will jumpstart your project. They reduce the learning curve and allow you to start using your chosen diagramming software right away. You can choose a template that matches your goals, start plugging in your data, and have a professional-looking diagram in minutes
  • Drag-and-drop elements: When you’re brainstorming the best workflow or expanding your network configuration, you’ll need to organize and reorganize your diagram a few times before you get it just right. Drag-and-drop functionality allows you to move elements around and expand your diagram to add in the elements you (oops!) forgot
  • Collaboration features: Brainstorming a new product, wireframing, creating an org chart, and documenting your user journey—these are team projects. Features like commenting and multi-user editing allow you to harness the whole team’s brainpower in real-time
