heym vs fastmcp
heym: Heym is an AI-native workflow automation platform built around LLMs, agents, and intelligent tooling. It provides a visual canvas to wire AI agents, vector stores, and integrations without coding. Heym supports multi-agent orchestration, RAG pipelines, MCP, and self-hosting with enterprise features included by default.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
