About BlocklyProp Solo (Beta)  
BlocklyProp Solo is like the original BlocklyProp, but does not need a user account and works in a single tab.  There is no online file storage or sharing; files may be downloaded and saved on the computer.  COPPA compliance is not an issue because BlocklyProp Solo does not collect or store any user data.  Try BlocklyProp Solo (Beta) here.
