Side-by-side comparison
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.
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.
