How to technically make or enable chrome devtools or something similar on android (not remote)?

I would like to make Chrome browser devtools available on mobile phones, to help an underprivileged audience with no access to desktop computers develop apps.

What would be technically needed to get something like chrome devtools work on the android phone itself?

If mobile browsers generally don’t ship with devtools, is there a way to make a cordova app to locally (on the android phone) connect to the app itself using the remote debugging protocol locally instead of on a desktop computer via USB?
