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	+ Unified, provider-agnostic API across many model vendors + First-class streaming and UI integration for web frameworks + Strong TypeScript ergonomics and type safety + Free and open source with a large, active community
Tradeoffs	− Newer framework with a smaller community than longer-established options − Strongest ergonomics within the Google/Gemini and Cloud ecosystem	− TypeScript/JavaScript only, with no Python support − Lighter-weight than full agent-orchestration frameworks for complex flows
