Enterprise Architect SaaS is the perfect cloud based delivery solution for corporate enterprise teams using Sparx Systems Enterprise Architect. Enterprise Architect supports a range of modeling frameworks and is the tool of choice for over one million users across the world.

Enterprise Architect SaaS deployment allows medium to large teams to quickly start and scale their modeling efforts without any internal operational overheads.

Traditionally, Enterprise Architect is deployed on site to end users’ machines and connects to a remote database. This can incur quite extensive deployment time, efforts and costs for larger organizations in terms of internal provision of infrastructure, setup and maintenance of software and databases.

With more teams moving to a 'Cloud First' strategy, the 'On Premises' setup is becoming obsolete. Enterprise Architect SaaS allows users to get on-boarded and start working almost immediately.

  • Fast on boarding, start modeling sooner
  • No setup overheads
  • Highly Secure AWS, Azure-based solutions
  • SSO-based user management
  • Effortless scaling
  • 5x faster deployment

Enterprise Architect stores preferences, workspaces, themes and other custom settings and resources in two major locations; the Windows Registry and the Windows "Appdata" directory. These are robust and industry standard methods. However in some cases it is convenient to place this information in a more accessible and more manageable location, usually to allow easier management, duplication, and persistence across platforms.

When using alternate storage locations for preferences and application data it is now possible to:

  • Backup and restore settings with ease
  • Set up multiple configurations on the same client PC
  • Preconfigure a PC with company approved settings
  • Preconfigure a PC with additional themes, workspaces, technologies
  • Move settings and preferences between machines

Trainers can:

  • Preconfigure their training machines with ease
  • Roll back to a base state after a session with minimal effort

Companies and Application Installers can:

  • Set up company approved installations
  • Pre-install technologies themes/workspaces
  • Roll back unwanted or unexpected user changes with ease
  • Roll back to a baseline installation
  • Set up Enterprise Architect in Secure / Sand-Boxed environments like Docker
  • Decouple Enterprise Architect's major settings and persistent application data from the local system/hard drive(s)


Improved Code Engineering/Code Editor to support for Java's new version up to Java 17/18
