Model Expert is available in two editions: Standard and Premium

Standard Edition

The standard edition of Model Expert is free. It includes the ability to generate package dashboards and meta-model diagrams from your EA model. From here you can get a quick understanding of what’s in your model and spot elements, diagrams and connectors that may be missing, inconsistent or wrong.

Standard edition also includes 30 days of all the Premium edition features…

Premium Edition

Premium edition provides fast navigation to find and fix issues higlighted in the dashboard and metamodel views.

It allows you to create and store reference models and rules – examples of modeling best practice – which can be used to quality check even more features of your models.

With Premium edition you can also apply those best practice modeling standards to new content as it is created in your model – giving your modelers real-time help and guidance to model right first time.

Compare editions

Model Expert Standard licences are available for single users only.

Premium edition licences are available as single user or Group Licences.

Each single user licence can be installed on a single computer.

Group Licence keys allow a pool of users to share a licence between them, up to a maximum number (up to 10, up to 30, or unlimited users).

No. Teams who wish to share access to Model Expert should buy Group licences. Note that unlike Floating licences, which are sized based on the the number of concurrent users, Model Expert group licences are sized for the total number of EA users.

Group Licences have been designed for larger organisations with distributed teams and team members who all need access to common software, but for whom the traditional licencing options are not suitable.


Having flexibility in the number of users who can share the software reduces your need to precisely forecast how your organisation will use Model Expert. A Group licence accommodates changing patterns of use:

If you are rolling out the software and are unsure of how quickly you will get to full deployment or if there is a company reorganisation and an unexpected change in team size or use happens, a Group Licence can flex with your needs.

Simple to manage

Group Licences are not dependent on a shared server to manage licences, making it simpler for IT support teams to implement.

Your Model Expert Group licence works independent of network changes and supports staff who may work both on-site and remotely.

There is no need to manage a register of keys.

Easy to Use

No need to be connected to the company network. No need to wait for a licence to become available. Users just load Model Expert onto each machine, enter a single key, and start work.

OR, include Model Expert in the software build on your cloud hosted EA platform, so that everyone can benefit. See Sparxinthecloud.com  for more details.

Operating System

Windows 7, 8 and 10

Virtual Environments

We do not test Model Expert in any virtual environments e.g. VMWare, Citrix:  there are too many of them, and too many combinations of OS, environment, EA version and Model Expert version. This is why we give youhave a 30-day trial!

However, we do have many customers using Model Expert successfully in virtual environments. And we will do our best to help you get it working.

Microsoft .NET Framework

3.5, 4.0, 4.5


Enterprise Architect

V8.0 (Ultimate, Corporate, desktop or EA Lite), and all later versions including V11, 12, 13, 14, 15, 16 (32-bit).

Note that Model Expert, in common with all other EA extensions, will not work with eaLite after eaLite V10 (i.e. v11 and above) due to a deliberate change in EA.

Databases supported

  • EAP
  • We test with Oracle, SQLServer and MySQL.
  • We know of issues using Model Expert with MySQL when it is running on a LINUX server, so DO NOT recommend this configuration
  • PostgreSQL also has issues, due to inconsistencies in the EA/SQL interface. Please contact us to discuss.

Firstly, you don’t need to re-install Model Expert: EA takes care of that.


If you are using Premium edition, You will need to re-enter your Model Expert Licence key. This is because your application settings, such as your licence key code, are stored by EA, but in a file which changes as you change EA versions. So, when you upgrade EA, ALL your Model Expert application settings are lost.

We’re sorry about this, but we just don’t have any way of going back and getting the settings from an old version of EA.

So you’ll need to re-enter your Model Expert licence key code in the Specialize | Model Expert | Licence Information dialogue screen.

(P.S. You can find your Model Expert key by logging in to www.eadocx.com and selecting Licences).

Model Expert can format all legal Unicode characters – so we believe it supports all languages using these characters.

It has been extensively tested with English EA models and documents (our native language), plus French, Dutch, Belgian, German and Spanish, Polish and Czech.  Other languages are still awaiting confirmation.

Please tell us about your experience using Model Expert in your own language.
