adk-js

adk-js is an open-source, code-first TypeScript toolkit designed for developers building sophisticated AI agents, offering granular control over agent logic, evaluation, and deployment. It targets engineers who need flexibility beyond low-code solutions, enabling them to define complex agent behaviors, test them rigorously, and integrate them into production systems. Its interesting because it bridges the gap between experimental AI frameworks and production-ready infrastructure, giving developers full code-level ownership while simplifying the orchestration of multi-step agent workflows.
