Web-SimStadt is a web application written in JRuby on Rails. It uses the same compiled Jars as the SimStadt desktop version, and was developed during SimStadt 1 and SimStadt 2 projects.

It lets the user pick a project, a CityGML file and a workflow: WebSimStadt1

and then runs the workflow and displays the corresponding results: WebSimStadt2

It is not available for public use yet, but might be open-sourced in the future, and be offered as a virtual machine or a container.
