Ask HN: What agent frameworks are you using, and how well do they work?

2•istvan_intrnd•1d ago
We’ve built and used our own custom agent framework for a while (before “agents” became a mainstream term), mainly because existing tools didn’t fit our needs around control, observability, and composability.

I’m curious what others are actually running in production today—custom frameworks, LangGraph, AutoGen, CrewAI, homegrown pipelines, etc. and how satisfied you are with them.

What’s working well? What breaks down at scale (debuggability, cost, determinism, tool orchestration, evals)?

A friend of mine is using N8N a lot, but he isn't a developer and I think that is the main reason. I think LangChain is the most popular, but there is always a trade off between upstart costs, and the cost of forcing a pre-fab to fit your needs as you grow. I personally have used NextJS's AI SDK a a lot since it is very web friendly (nodejs/JS) https://ai-sdk.dev/docs/introduction.
