A Reddit user argues that building an agent is a weekend project, but operating twenty across a team is another story, and breaks down 5 tools covering the production stack:
- LangGraph: strongest option for deterministic, graph-based control of complex multi-agent steps
- Port.io: solves agent sprawl with a centralized registry logging each agent's owner, environment scope, and approved permissions
- PydanticAI: typed, predictable outputs that integrate cleanly into existing microservices
- Langfuse: essential for debugging token costs, prompt drift, and failed tool calls
- Relevance AI / n8n: low-code internal ops workflows for non-engineering teams
