I used LangChain early on in it's life. People crap on their documentation but at least at that point in time I had no problem with it. I like reading source code so I'd find myself reading the code for further comprehension anyway. In my case - I'm a seasoned engineer who was discovering LLMs and thought LangChain suited that way of learning pretty well.
When it came to building anything real beyond toy examples, I quickly outgrew it and haven't looked back. We don't use any LC in production. So while LC does get a lot of hate from time to time (as you see in a lot of peers posts here) I do owe them some credit for helping bridge my learning of this domain.
