Ask HN: How are you monitoring AI agents in production?
With the recent incidents (DataTalks database wipe by Claude Code, Replit agent deleting data during code freeze), it's clear that running AI agents in production without observability is risky.<p>Common failure modes I've seen: no visibility into what the agent did step-by-step, surprise

I run a team of Claude agents that ships PRs to production — open source
I've been running a multi-agent system in production for a few months — a co-CTO agent + specialist agents (PM, dev, ops) that handle real engineering work end-to-end: design specs, code review, PR implementation, deploys, monitoring. The architecture: * Each agent is a Docker container running `c

For complex workflow automation, AutoGen may hold an edge, but for scalable multi-agent systems, LangChain is preferred.
LangChain's diverse pricing structure remains unstressed in reviews, possibly indicating cost-effectiveness, whereas AutoGen is perceived as reasonably priced against its feature set.
LangChain benefits from superior community support, evidenced by its significant GitHub stars and npm downloads, compared to AutoGen's smaller community presence.
While not directly integrated, their compatible AI frameworks allow potential simultaneous use with custom implementation for specialized needs.
LangChain is generally easier due to its comprehensive documentation and broad community, unlike AutoGen, which may involve more initial setup due to documentation gaps.
