💡 Our Take
Choose Google ADK if you need multi-language SDKs, MCP-native tool support, and Vertex AI deployment. Choose Strands Agents (AWS) if you're an AWS-native shop deploying to Bedrock and want first-party AWS integration with Lambda and Step Functions.
Google ADK - Pros & Cons
Pros
- ✓Code-first abstractions support versioning and testable agent behavior
- ✓Evaluation and deployment workflows address more than prompt prototyping
- ✓Natural fit for teams already using Gemini and Google Cloud
Cons
- ✗Requires software engineering skills and operational ownership
- ✗End-to-end cost depends on separate model and cloud services
- ✗Deep Google integration may reduce portability to other stacks
Strands Agents - Pros & Cons
Pros
- ✓14M+ downloads and rapidly growing community since May 2025 release make it one of the most adopted agent SDKs available
- ✓Model-agnostic design prevents vendor lock-in: switch between Bedrock, OpenAI, Anthropic, or local models without code changes
- ✓Three-line agent creation for simple cases scales up to full multi-agent orchestration for complex production systems
- ✓Both Python and TypeScript SDKs cover the two most common AI development ecosystems
- ✓Enterprise-proven: Eightcap reported 30-minute-to-45-second investigation time reduction and $5M in operational cost savings
- ✓Native AWS deployment path with Bedrock AgentCore, Guardrails, and IAM, but not locked to AWS infrastructure
- ✓Built-in MCP client support connects to thousands of external tool servers and data sources
Cons
- ✗AWS-centric documentation and examples mean non-AWS deployments require more self-guided configuration
- ✗Model-driven approach means less predictable agent behavior compared to hardcoded workflow frameworks like LangGraph
- ✗Newer framework (May 2025) with smaller ecosystem of community tools and tutorials than LangChain or CrewAI
- ✗Debugging unexpected tool choices requires understanding both the LLM's reasoning and the tool selection mechanism
- ✗No built-in UI components: agents are backend-only, requiring separate frontend development for user-facing applications
