Claude Agent SDK

Anthropic's first-party agent SDK for building production agents on top of Claude. Native MCP support, sub-agents, tool use, and prompt caching out of the box. Routinely benchmarked alongside Strands, LangGraph, and the OpenAI Agents SDK in 2026 framework comparisons.

Microsoft Agent Framework

Microsoft Agent Framework 1.0 (April 2026) is the official merger of AutoGen and Semantic Kernel into a single production-ready SDK for .NET and Python. Microsoft publishes a migration path from both predecessors; this is the recommended Microsoft path for new agentic applications.
