CrewAI vs LangGraph vs MS Agent Framework 2026

Description

Microsoft killed Autogen on April 7, 2026 — and most of the agent-framework tutorials you've read this year are now wrong. In this 5-minute deep dive we settle the 2026 AI agent framework war: 👉 Autogen — frozen into maintenance mode (skip unless you're legacy) 👉 CrewAI — the fastest path from zero to a working multi-agent crew (3 lines of Python, 60% of the Fortune 500 already on it) 👉 LangGraph — graph-based orchestration for production systems where every branch must be auditable (finance, healthcare, legal) 👉 Microsoft Agent Framework 1.0 — the merger of Autogen + Semantic Kernel, with native A2A, MCP, .NET / Python, and Azure AI Foundry integration You'll get an honest decision tree (when to pick which), the real winner nobody is saying out loud (use TWO frameworks, not one), and the lever that actually moves agent quality in production: your eval harness, not your framework debate. If you're choosing an AI agent framework in 2026, watch this before you write a single line of code. Wrong framework = 6 wasted months. ═══ CHAPTERS ═══════════════════════════════════════════════ 0:00  Microsoft Killed Autogen (April 7, 2026) 0:32  Why Every AI Agent Tutorial Is Now Outdated 1:10  Verdict on Autogen: Skip Unless You're Legacy 1:27  CrewAI Deep Dive — Speed + 60% Fortune 500 2:06  LangGraph Deep Dive — Graphs Beat Conversations 2:54  Microsoft Agent Framework 1.0 Explained 3:47  Decision Tree: Which One Should YOU Pick 4:26  The Real Winner: Use TWO Frameworks 4:43  Prototype ≠ Production Trap 4:56  The Real Lever — Evals Framework Debates 5:09  Outro ════════════════════════════════════════════════════════════ 🔗 Resources we reference - Microsoft Agent Framework v1.0 release: aka.ms/agent-framework - CrewAI docs: docs.crewai.com - LangGraph docs: langchain-ai.github.io/langgraph 🎬 Made by DEEPTECH AI LABS — production-grade AI explainers.
