I'm just in the process of moving from a prototype in N8N's agent tools to an actual system that could be self-hosted.

I've read a lot of comments that most pragmatic shops have dumped langchain/graph, haystack, crew etc for their own internal code that does everything more simply, but I can't currently conceptualize how tooling etc is actually done in the real world.

Do you have any links or docs that you've used as a basis for the work you could share? Thanks.
