The editorial take
Choose Haystack for production RAG pipelines with typed components, YAML deployment, and evaluation harnesses against golden test sets. Choose AutoGen if you're researching or prototyping conversational multi-agent patterns where agents debate, critique, and refine each other's outputs and Microsoft's research-driven roadmap is a fit.
Microsoft AutoGen - Pros & Cons
Pros
- ✓MIT-licensed open source with active development
- ✓Backed by Microsoft Research with strong academic foundations
- ✓v0.4's async event-driven architecture enables scalable agent systems
- ✓Native cross-language support for Python and .NET
- ✓AutoGen Studio provides a no-code interface for rapid prototyping
- ✓Tight Azure AI Foundry integration for enterprise deployment
Cons
- ✗Microsoft's agent strategy is evolving; monitor official announcements for roadmap changes
- ✗v0.4 introduced major breaking changes from v0.2, requiring significant migration effort
- ✗Steep learning curve compared to simpler frameworks like CrewAI
- ✗AutoGen Studio is experimental and not production-ready
- ✗No commercial support tier outside of Azure AI Foundry
Haystack - Pros & Cons
Pros
- ✓Explicit pipeline graph makes debugging retrieval and generation quality straightforward
- ✓Component swaps (change retriever, reranker, model) don't require rewriting the pipeline
- ✓Mature at scale — used in production at Airbus and Deutsche Telekom
- ✓MCP-native tool integration means agents can talk to any MCP server without adapters
- ✓Apache 2.0 with no vendor lock-in; deepset Cloud is optional, not required
Cons
- ✗Learning curve is steeper than a LangChain-style chain — you have to think in graphs
- ✗Python-only (no first-class TypeScript/Node support)
- ✗Fewer community templates than LangChain, so you build more from primitives
- ✗deepset Cloud pricing ($99+/mo) is opaque compared to per-seat SaaS
- ✗Async pipeline support is newer and still stabilizing across all components
