Strengths	+ 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	+ Deep integration with OpenAI features + Built-in handoff and guardrail primitives
Tradeoffs	− Newer framework with a smaller community than longer-established options − Strongest ergonomics within the Google/Gemini and Cloud ecosystem	− OpenAI-first; cross-provider use is awkward
