COMPARISONS

Tool-by-tool engineering read-outs

Each comparison ends with a rule, not a hedge. We commit to refreshing every comparison page quarterly with a Last-verified stamp.

AutoGen vs CrewAI

Conversation cost economics versus role-coordination overhead. Both have ceilings.

Last verified April 2026
AutoGen vs LangGraph

Conversation expressiveness versus graph determinism. Production cost is the dividing line.

Founder, Digital Signet

Oliver runs Digital Signet, a research and product studio that operates ~500 production sites with AI agents as the engineering layer. The Digital Signet portfolio is built using a continuous AI-agent build pipeline, one of the largest agent-operated publishing operations on the open web. The handbook draws directly from those deployments: real cost data, real failure modes, real recovery patterns.
