I will be linking all of the open-source financial decision framework tools on this page. To start, I will provide the links to the Streamlit application.
Please note that applications may take a few seconds to load. If the application hasn’t been opened for several hours, you may need to select the button “Wake me up”. This will spin up the application. I am considering alternative hosting options outside of Streamlit to make this more efficient.
*Please reach out if you would like to see custom functionality and/or notice any bugs.
