AutoGen - Pros & Cons
Pros
- ✓Free and open source (MIT license) with no usage restrictions or commercial tiers
- ✓AutoGen Studio provides a visual no-code builder that no other major agent framework offers for free
- ✓Cross-language support (Python and .NET) serves enterprise teams with mixed codebases
- ✓OpenTelemetry observability built into v0.4 for production monitoring and debugging
- ✓Microsoft Research backing means long-term investment without venture-driven monetization pressure
- ✓Layered API design (Core, AgentChat, Extensions) lets you pick the right abstraction level
- ✓Microsoft Agent Framework unification provides a clear path from prototype to enterprise deployment via Foundry
Cons
- ✗Documentation quality is a known problem: gaps, outdated v0.2 references, and insufficient examples for v0.4
- ✗v0.4 is a complete rewrite, so most online tutorials and examples reference the incompatible v0.2 API
- ✗AG2 fork creates ecosystem confusion about which project to use and fragments community resources
- ✗Structured outputs reported as unreliable by users on Reddit, requiring workarounds for deterministic agent responses
- ✗No built-in budget controls for LLM API spending across multi-agent workflows — cost management is entirely your responsibility
- ✗Steeper learning curve than CrewAI or LangGraph due to lower-level abstractions and less guided onboarding
Docling - Pros & Cons
Pros
- ✓Best-in-class PDF parsing with accurate table extraction, formula detection, and multi-column layout understanding
- ✓Runs entirely locally with zero cloud dependency — critical for teams handling sensitive or regulated documents
- ✓MIT license with no usage limits, no pricing tiers, and no vendor lock-in
- ✓First-class integrations with LangChain, LlamaIndex, CrewAI, and MCP protocol for immediate use in existing AI stacks
- ✓Actively maintained by IBM Research with aggressive release cadence and growing LF AI & Data Foundation backing
Cons
- ✗CPU-only parsing can be slow on large PDFs — GPU acceleration with Granite-Docling model is faster but requires more setup
- ✗Python-only ecosystem means Node.js or Java teams need to wrap it as a microservice or use the MCP server
- ✗Advanced models (Granite-Docling VLM, Heron layout) require downloading multi-hundred-MB model weights
