The Structurizr renderer is available in a number of versions, covering different usage scenarios.


Packaged as a Docker container, and designed for developers, this version of Structurizr provides a way to quickly view diagrams, documentation, and architecture decision records.

(free; no sign up required)

Cloud service

Our cloud service allows you to get started with Structurizr quickly, without needing to host and update software on your own servers.

(free and paid)


We also have a version of Structurizr that can be run on your own infrastructure (local servers or cloud), providing the majority of the same features found in the cloud service.
