JADE is a Java-based agent development framework that simplifies the creation of distributed multi-agent systems. It provides FIPA-compliant infrastructure including a runtime environment, message transport, directory facilitator, and agent management. Developers write agent classes in Java, deploy them in containers, and use graphical tools like RMA and Sniffer for debugging and monitoring. JADE supports agent mobility, behavior scheduling, and lifecycle operations, enabling scalable and modular designs for research, IoT coordination, simulations, and enterprise automation.

Fetch.ai’s Autonomous Economic Agents (AEA) Framework is an open-source Python SDK and CLI toolset for creating modular, autonomous agents that can negotiate, transact, and collaborate in decentralized environments. It includes scaffolding commands to generate agent projects, templates for protocols and skills, connection modules to integrate with multiple ledgers (Ethereum, Cosmos, etc.), contract interfaces, behavior and decision‐making components, testing and simulation utilities, and a publishing mechanism to distribute agents on the Open Economic Framework network. Developers leverage its modular architecture to rapidly prototype digital workers for DeFi trading, data marketplaces, IoT coordination, and supply chain automation.
