Created custom graphical modeling workbenches support both your specific visual notation and your own domain concepts.
a Configuration File
Visual editors are declared by a configuration file which is interpreted at runtime, meaning very few lines of code and easy tuning.
a Web Server
The backend of your modeling tool is deployed on a web server running with state-of-the-art technologies: Spring, React, PostgreSQL, GraphQL.
a Web Browser
Once deployed on a server, just start using the modeling tool directly from a web browser, without specific installation on user's desktop.
