Google ADK
code-first, ga, enterprise deploy — with gemini gravity
a clean, ga code-first framework with strong multi-agent orchestration and a real enterprise deploy story on vertex — model-agnostic via litellm, but at its best on gemini and gcp.
google's agent development kit pairs an llmagent with deterministic workflow agents (sequential, parallel, loop) for orchestration, plus built-in evaluation, tracing, and native a2a for agent-to-agent communication. it's ga-grade with a proper deploy path to vertex ai agent engine and cloud run, and hierarchical multi-agent is a genuine strength. it's model-agnostic through litellm (anthropic, meta, mistral, ollama, vllm) even though it's tuned for gemini.
the gravity is real: the best features light up on google cloud and gemini, so the more of your stack lives elsewhere, the less of adk you'll use. within the google ecosystem it's a strong, well-designed choice.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
