Pros
  • Clean Python API
  • Strong role/goal abstractions
  • Active community
  • Hosted platform for deployment
  • First-class C#, Python, and Java SDKs, rare among agent frameworks
  • Open source (MIT) and backed by Microsoft with active roadmap
  • Deep Azure OpenAI, Azure AI Search, and Cosmos DB integrations
  • Built-in filters, telemetry, and DI patterns suited to enterprise apps
  • Plugin model works with native functions and OpenAPI-described tools
Cons
  • Production observability still maturing
  • Debugging multi-agent flows is hard
  • APIs have churned across versions; upgrades can be painful
  • Agent and Process frameworks still maturing vs. established rivals
  • Best-in-class only if you're already in the Microsoft ecosystem
  • Steeper learning curve than lightweight prompt libraries
