Key Features
  • • Multi-language SDKs: Python 2.0 Beta, TypeScript 1.0, Go, and Java
  • • LLM agents, sequential, parallel, loop, and custom workflow agents
  • • Built-in evaluation framework with criteria, user simulation, and environment simulation
  • • Model-Driven Tool Orchestration: The LLM dynamically selects and sequences tools based on the task rather than following hardcoded workflows, enabling more natural and adaptive agent behavior that adjusts its approach based on intermediate results.
  • • Multi-Provider LLM Support: Works with Amazon Bedrock, Anthropic, OpenAI, Ollama, LiteLLM, and any OpenAI-compatible API. Switch providers by changing a single configuration without modifying agent logic or tool definitions.
  • • Built-in Tool Library and Custom Decorators: Ships with 20+ ready-to-use tools for file I/O, shell commands, HTTP requests, code execution, RAG retrieval, and AWS service interactions. Extend with custom tools using a simple @tool Python decorator.

The editorial 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
