murmur vs MetaGPT
murmur: Murmur is a secure, end-to-end encrypted multi-agent communication bus that enables AI models like Claude and GPT to talk directly to each other. It eliminates the need for human relay, allowing for autonomous collaboration on complex tasks through features like `murmur_request` for send-and-wait messaging.; 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).

Features
murmur01E2E Encryption & Digital Signatures: Uses X25519 + XChaCha20-Poly1305 AEAD for encryption and Ed25519 for message authentication, ensuring secure communication.
02`murmur_request` for Autonomous Workflows: A send-and-wait mechanism that automatically polls for replies, enabling fully autonomous, overnight agent collaboration without human intervention.
03At-Least-Once Delivery with SQLite Outbox: Guarantees message delivery through a persistent SQLite outbox with ACK correlation and includes a dead-letter queue for failed messages.
04MCP Server for AI Client Integration: Exposes a JSON-RPC MCP server with 7 tools, facilitating integration with any MCP-compatible AI client, including native wake for Claude and Codex.
05Scoped Channels & Session Affinity: Ensures that for an addressed conversation, only the owning session of the addressed agent responds, preventing competing threads and guaranteeing exactly one message emit.
MetaGPT01Accepts single-line requirements and generates comprehensive software artifacts (e.g., user stories, APIs, documentation).
02Emulates a software company by assigning distinct roles (e.g., PM, Architect, Engineer) to LLM agents.
03Orchestrates collaborative processes using Standard Operating Procedures (SOPs) for complex task completion.
04Supports integration with various Large Language Models and APIs (e.g., OpenAI, Azure, Ollama, Groq).
05Enables advanced capabilities like data interpretation and automated workflow generation.
