Javascript Extensions and Source Code



This is actually two questions:

  • Javascript extensions are a very powerful tool to extend Scratch and also Mblock, however it seems that modifying them doesn’t alter the behaviour of your application. I’m very interested on extending some functionalities in order to make easier its usage for kids and therefore being able to use it at schools. I can’t find also a way to add new extensions that appear on the menu list. Is there any way to do it?

  • Linked to the previous question, I’d like to know when do you plan to release the source code so the community can collaborate on improving the software. I see that it is licensed under GNU General Public License (, so at some point I guess that it should be released.



Hello, @deivkk, you may not see this because:


But if you do, I have made a JavaScript Extension available on GitHub:

Thanks for your time,
