Summary
2026 systematic comparison of the three dominant Python multi-agent frameworks. Tests identical multi-step workflows: sequential pipelines, parallel agent execution, state persistence across sessions, error recovery, human-in-the-loop interruption, and integration with external tools. Includes benchmarks on development time and runtime performance.
PUMA Relevance
Critical reference for PUMA’s framework choice justification (Section 1.4 — approach and methodology). The HITL interruption comparison shows LangGraph as the strongest implementation — directly supporting PUMA’s Constitution Article 4 (HITL mandatory). The error recovery comparison motivates PUMA’s retry design (Pydantic AI + LangGraph checkpoints for recovery).
