About Terrastruct
What is Terrastruct?
Terrastruct is the company behind D2 Studio and the D2 diagramming language. D2 Studio is a modern developer tool that combines the speed of text-to-diagram with the precision of drag-and-drop, allowing you to create and maintain software architecture diagrams.
What problem does it solve?
It eliminates the friction of using generic diagramming tools that feel clunky and hard to maintain. With D2 Studio, you can express diagrams in simple text, autoformat, and sync edits bidirectionally between text and GUI, making diagram creation and updates fast and painless.
Who is it for?
Terrastruct is ideal for developers, software architects, and technical teams who need to create clear, multi-layered diagrams of complex systems. It's especially useful for documentation, design reviews, and onboarding. If you prefer non-technical diagramming with lots of freeform drawing, this might not be the best fit.
Real Use Cases
Visualizing microservices architecture, mapping system dependencies, creating network diagrams, and documenting incident response scenarios (e.g., what happens when a server fails).
Key features
- Text-to-diagram — Express complex architectures in a simple DSL you can learn in minutes.
- Bidirectional editing — Tweak objects on the board, and your changes sync back to the text (and vice versa).
- Autoformat — Save time with automatic style and indentation on every save.
- Syntax highlighting — Enjoy native editing in Vim and VSCode with dedicated extensions.
- Themes & styles — Go from sketch to presentable diagrams for blogs and wikis in minutes.
- Icons & images — Embed handpicked icons or search Google images directly in the app.
- Interactive, multi-layered diagrams — Zoom in/out, define scenarios for each layer, and handle complex diagrams with ease.
