lavern vs MetaGPT

lavern: Lavern is a multi-agent legal system featuring 67 specialized agents and orchestrators that coordinate through a debate protocol to analyze legal documents. It reads documents, posts findings with cited evidence, runs three layers of verification, and pauses at human gates before critical decisions, supporting Anthropic, Mistral, or local Ollama LLMs.; 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.

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).
