I use n8n for managing ChatGPT's API and to connect it to other APIs like gmail. It helps abstract away the authentication side of APIs which can be very cumbersome to manage.

It also helped me better understand the chatgpt API. N8n allows you to code in raw javascript or python which has allowed me to branch out to pure python.

I would say that no-code low code has a place as a stepping stone, that can allow other invested parties besides developers to manage inter departmental flow and build a blueprint that can be redone with actual engineers in the preferred manner.
