💡 Our Take
Choose Google ADK if you prefer opinionated workflow primitives (sequential, parallel, loop), built-in evaluation, and a local debugging UI shipped out of the box. Choose LangGraph if you need maximum flexibility, a larger ecosystem of integrations, and prefer graph-based agent orchestration with LangChain compatibility.
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
LangGraph - Pros & Cons
Pros
- ✓Open-source library is MIT-licensed and runs anywhere without platform lock-in
- ✓Native checkpointing makes durable, resumable, human-in-the-loop agents straightforward
- ✓First-class multi-agent patterns: supervisor, hierarchical, sequential, parallel branches
- ✓Tight integration with LangSmith for production observability, evaluations, and replays
- ✓Active maintenance from the LangChain team with frequent releases and strong community
Cons
- ✗More verbose than LangChain for simple agents — explicit state schemas and edge functions add overhead
- ✗LangSmith trace pricing ($2.50/1k base traces) is a real cost at production scale
- ✗LCU + deployment-minute billing makes pricing harder to predict than seat-only competitors
- ✗Steeper learning curve than role-based frameworks like CrewAI for newcomers
- ✗Best documented in Python; JavaScript SDK exists but lags in features
