Is there an alternate extension creator?

I installed Java SDK and JDK, Git, and Apache Ant, but the Git Bash just shows an error after typing extensions and the error -> bash: ant: command not found . Is there an alternate method or extension creator. I added all the environment variables from KiO4’s tutorial on his/her website. I am using Windows 10 2004.

Link to the tutorial I followed:

You can use

Advantages -

  • No need to setup java, apache.
  • No need to install any IDE.

Disadvantages -

  • You can't use custom package.
  • Not works offline
  • You can't import external libraries
  • It takes around 5 to 7 minutes to compile while app inventor sources or extension template takes only 15 to 20 seconds.

Here advantages < disadvantages therefore I will suggest you to do it in your pc.

here are some tutorials.


You can use to let GitHub actions build the extension for you.


If you're using the extension template, it states in the README that ant 1.10 is needed. You should set up ant on your PATH if you're planning to go the route of building locally. (Note: ant is also required for building App Inventor generally).


Thanks @Techno_Vedang. Been looking for something like this for a while, since school-owned Chromebooks can't run any of the app/extensions/editors that you would normally use for extension-making.

I cloned the repository and I end up with build failed.
