What "barrier" are you talking about? Surely in a developing country having a human code instead of using a no-code tool, is more likely than in a developed country, as humans are more expensive the in latter??
But since they are looking to earn money as well, they prefer to use no-code.
I'm talking from experience and from numbers: out of 60k no-code experts that we have, most of them (95%+) are from developing countries and not from developed ones
