Google Launches ADK for TypeScript: Code-First Agent Framework Extends to JavaScript Ecosystem

Google Developers Blog·medium signal

Google released Agent Development Kit (ADK) for TypeScript, completing a four-language ecosystem (Python, Java, Go, TypeScript). The framework enables TypeScript/JavaScript developers to build AI agents using familiar tooling — npm install @google/adk, define logic/tools/orchestration in code, deploy to local/container/Cloud Run. It's model-agnostic (supports Gemini 3 Pro, Flash, and third-party models) and includes @google/adk-devtools for interactive CLI and web UI debugging. ADK for TS makes Google's agent framework accessible to the largest single-language developer community.
