Better team collaboration

Get started

Handle complexity

D2 Studio is a dynamic diagram, and layers information, letting you express complexity in simple ways.

Our navigation lets you focus on one layer of abstraction at a time, define scenarios for that layer, and step through sequences of events.

D2 Studio allows for clear and dynamic diagrams, unlike static diagrams from our competitors

Built for engineers

Our app includes first-class support for elements you're familiar with and care about. We’re supercharged with hotkeys for power users, and we have a feature called Declarative Diagramming that turns your text into diagram. Learn more

We’ve also included a huge library of handpicked icons to cover whatever you want to express.

D2 Studio is uniquely built for engineers in mind

Integration with your workflow

Link directly from diagram to lines of code, or any other external documentation.

D2 Studio can automatically sync your diagram to a Github repository. Whenever there are changes, our bot pushes revisions to a repository of your choice.

See demo

D2 Studio automatically keeps your diagram up to date with changes
