CrewAI - Pros & Cons
Pros
- ✓Role/goal/backstory abstraction is genuinely easier to reason about than raw graphs
- ✓Fast time-to-first-working-crew — hello-world in under an hour
- ✓Strong enterprise story with visual designer and monitoring
- ✓Excellent MCP support means you can reuse Claude/Cursor tool servers
- ✓MIT license and a clear open-core boundary
Cons
- ✗Fine-grained control (custom state, complex loops) is easier in LangGraph
- ✗Enterprise features are pay-only — the free tier is intentionally basic
- ✗Multi-agent workflows can be token-hungry; budget carefully
- ✗Fast-moving API — expect small breaking changes across minor versions
Google Agent Development Kit (ADK) - Pros & Cons
Pros
- ✓Completely free and open-source under Apache 2.0 license
- ✓Model-agnostic — works with Gemini, GPT, Claude, and open-source models via LiteLLM
- ✓Built-in evaluation framework that LangChain and CrewAI lack out of the box
- ✓First-class Vertex AI Agent Engine deployment with managed scaling and monitoring
- ✓Backed by Google's engineering team — same framework powers Agentspace internally
- ✓Supports both Python (1.0.0+) and Java (0.1.0+), unlike most single-language competitors
- ✓Native bidirectional streaming for voice and video agent experiences
Cons
- ✗Requires Python or Java programming knowledge — no visual builder
- ✗Released April 2025, so community is smaller than LangChain's 90K+ GitHub stars
- ✗Documentation still maturing for advanced multi-agent patterns
- ✗Best deployment experience locked to Google Cloud / Vertex AI
- ✗Fewer third-party integrations than LangChain's 700+ ecosystem connectors
- ✗Steeper learning curve than no-code alternatives like Relevance AI or BuildShip
