agent-kit and adk-js
These are competitors in the agent development space—both provide TypeScript-based frameworks for building AI agents with structured tooling, though AgentKit emphasizes multi-agent orchestration via MCP while ADK-JS focuses on evaluation and deployment workflows.
About agent-kit
inngest/agent-kit
AgentKit: Build multi-agent networks in TypeScript with deterministic routing and rich tooling via MCP.
AgentKit helps TypeScript developers build robust multi-agent systems that can handle complex workflows. It takes in plain language requests and orchestrates various 'agents' (which are essentially specialized AI functions) to collaboratively process information and produce a final output. This tool is for developers creating AI applications that require agents to work together efficiently and reliably.
About adk-js
google/adk-js
An open-source, code-first Typescript toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.
This toolkit helps TypeScript developers build and deploy advanced AI agents. You can define agent behaviors and integrations with tools and Google Cloud services directly in code. The output is a robust, testable, and version-controlled AI agent, used by software engineers building intelligent applications.
