Pricing	freemium	freemium
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	+ Transparent, modular pipeline architecture + Strong, mature support for RAG and retrieval workflows + Broad ecosystem of model and document-store integrations + Production focus with a commercial platform option from deepset
Tradeoffs	− Newer framework with a smaller community than longer-established options − Strongest ergonomics within the Google/Gemini and Cloud ecosystem	− Pipeline/component model adds boilerplate for simple tasks − Historically RAG-centric, with agents added more recently
