Strengths	+ Proven conversational multi-agent patterns inherited from AutoGen + Open, contribution-based community governance + Built-in code execution and human-in-the-loop support + Model-agnostic across major LLM providers	+ Code-first design with explicit control over orchestration and tools + Native multi-agent composition and delegation + Built-in evaluation and local dev CLI (adk run, adk web) + Backed by Google with paths to managed Vertex AI deployment
Tradeoffs	− Branding and lineage confusion with AutoGen and Microsoft Agent Framework − Still pre-1.0 with evolving APIs − Smaller institutional backing than vendor-led frameworks	− Newer framework with a smaller community than longer-established options − Strongest ergonomics within the Google/Gemini and Cloud ecosystem
