Google ADK in brief

Open-source, code-first Python toolkit for building, evaluating and deploying agents.

ADK for Python 2.13.0 promotes 12 experimental features to stable, adds a classifier node for fast workflow routing, live audio with barge-in, and MongoDB session and memory services.

What it does well: Apache-2.0 license; Broad feature set: eval, live audio, memory services; Detailed release notes with a breaking-change section.

Where it falls short: Breaking telemetry default in 2.13.0; Several new services are experimental; We only ran it against a local model through LiteLLM, not Gemini, and did not test the telemetry change.

Latest version we cover: v2.13.0 (Oct 22, 2026). Vendor: Google.
