n8n is a fair-code workflow automation platform that now features powerful AI agent nodes. Build complex agentic workflows with tool use, memory, and multi-step reasoning — all through a visual interface.
Anthropic's SDK for building production-grade AI agents
Agent Frameworks
The Claude Agent SDK provides a lightweight, Python-first framework for building agents with Claude. Features include tool use, multi-turn conversations, guardrails, and structured handoffs between agents.
Registry and marketplace for Model Context Protocol (MCP) servers
Agent Frameworks
Smithery is the central hub for discovering and sharing MCP servers. It enables AI agents to connect to external tools, APIs, and data sources through the standardized Model Context Protocol.
OpenAI's official SDK for building multi-agent workflows
Agent Frameworks
The OpenAI Agents SDK provides primitives for building agentic AI applications: agents with instructions and tools, handoffs between agents, guardrails for input/output validation, and tracing for debugging.
AutoGPT is one of the first and most popular autonomous AI agent projects. It chains together LLM calls to autonomously achieve goals you set, breaking them down into sub-tasks and executing them.
