The Structurizr on-premises installation is a standalone version of Structurizr that can be run locally on your own infrastructure, and includes the majority of the features found in the cloud service. Please see the pricing page for pricing, and the products page for the differences in feature set.

The Structurizr on-premises installation (the Application) is licensed, not sold, to you by Structurizr Limited for use strictly in accordance with the terms of the End User License Agreement. By licensing the Application, Structurizr Limited grants you a license to install and use the Application on your own infrastructure. Licenses are granted on a perpetual license, although you will only have access to software updates for the duration of a valid subscription.

Each on-premises license will be associated with a user account on structurizr.com, so you will need to sign up for a free account before purchasing. After purchase, on-premises installation downloads are available on a self-service basis, from your dashboard (sign in required).

Basic installation

This is designed for use on a single server, and for ease of installation, with all workspace data and users being stored on the local file system.

Structurizr Lite replaces the previous free, 1 workspace, on-premises installation.

Authentication and high availability add-ons

The authentication add-on provides support for authentication with LDAP and SAML 2.0 - see On-premises installation - Authentication for more details. The high availability add-on provides support for external data storage options (Amazon Web Services S3 and Elasticsearch are currently supported).
