Products in this niche provide the libraries, runtimes, and communication standards that enable multiple autonomous AI agents to collaborate and execute complex workflows. They are primarily used by software engineers and technical teams building distributed, cooperative agentic systems. Unlike single-agent builders or standard LLM chaining tools, these solutions focus specifically on inter-agent messaging, peer-to-peer networking, and decentralized coordination protocols.

This theme's recent-window count is below the current min-count filter, so it does not appear in the opportunity scorecard.
