Mercury certainly seems worthy of keeping an eye out. Voila is the obvious competitor to this. There are also different oranges and apples such as Dash, Streamlit, Panel: https://anaconda.cloud/dashboardlandscape https://anaconda.cloud/dashboardlandscape - obviously Anaconda is a bit biased here. I suppose the biggest limitation to Mercury is the limited number of widgets. Good for quick demos. Also deployment is a bit unclear at the moment - I wonder how easy it is to keep Mercury deployed in a separate Docker container - that is I do not want to keep random ports open on my notebook server. Then again probably deployment/hosting is how Mercury expects to make some money.
