Terrastruct is the preferred alternative to Gliffy
You wouldn't write code on Microsoft Word. Use the right tool for the job. Terrastruct offers your team better ways to document work and more features that can be customized to tackle software architecture.
Terrastruct 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.
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.
Integration with your workflow
Link directly from diagram to lines of code, or any other external documentation.
Terrastruct can automatically sync your diagram to a Github repository. Whenever there are changes, our bot pushes revisions to a repository of your choice.
