Why Miro is your best activity diagram tool
Optimize faster
Miro’s Diagramming mode makes it easy to create a UML activity diagram — including a curated diagramming toolbar, layers, and other dedicated tools. You'll have everything you need to build and share your visualization faster and get instant feedback.
From ideation to implementation
Design your technical plans by breaking down large processes into chains, making them easy to analyze and implement. Offer a high-level view to managers and maximize collaboration across teams by creating activity diagrams that resonate and make sense.
Quickly draw entire systems
Use Miro’s extensive UML shape pack to add activity diagram symbols, and use Smart Drawing to seamlessly create shapes and lines. Get a clearer view of your flow by adding and color-coding ellipses.
One source of truth
Say goodbye to back and forth with Miro’s extensive collaboration features. Easily draw activity diagrams, add Kanban boards, timelines, and other artifacts to one shared space. Invite your team to your Miro board and get everyone on the same page instantly.
