MetaGPT vs neo-agent-brain
MetaGPT: MetaGPT is a multi-agent framework that assigns different roles to LLMs, enabling them to collaborate on complex software development tasks. It takes a one-line requirement and outputs comprehensive project artifacts, mimicking a software company's entire process.; neo-agent-brain: Neo-agent-brain serves as the 'Brain' of the Neo.mjs AI engineering team, functioning as an Agent OS. It provides persistent identity, shared institutional memory, repository knowledge, and durable coordination for a swarm of AI maintainers from diverse model families, enabling robust cross-family review and self-evolving workflows.

When to choose:
- You want to experiment with or demonstrate the 'software company SOP' multi-agent pattern (PM, architect, engineer generating specs and code).
- You are looking for the reference implementation of research papers from the team such as AFlow, SPO, and AOT.
When to skip:
- You want an actively updated general-purpose production agent framework; the repository's last push was in January 2026.
- You are on Python 3.12+ or do not want to install Node.js and pnpm alongside Python (README specifies Python 3.9–3.11).
