I personally believe in flexing opensource projects, especially when they're this robust, it would save a lot of development time and provide a flexible framework for easy tweaks in the future. Using a framework like the above would provide an environment that cards provides where no code, GUI edits and functions and be changed on the fly. Additionally we can just fork any of these projects to make deeper tweaks as needed.

Front Ends

Web Frameworks

   https://fastapi.tiangolo.com/project-generation/ (sql library https://github.com/tiangolo/sqlmodel)

   https://jamsocket.com/ a hosted platform for session backends, servers that are created by an application on demand, typically run for the duration of a user's session, and are spun down when no longer in use.

   https://github.com/IvorySQL/IvorySQL - Oracle compatible PostgreSQL, I think this it would be a fun exercise to deploy CARDS against it to see if we can't get ourselves out of Oracle's grasp.
