Overview

AgentKit is an open-source TypeScript framework designed for developers who want to build production-ready AI agents without reinventing core orchestration logic. It provides primitives for defining agents, attaching tools, managing state, and coordinating multi-agent workflows in a type-safe way. The library focuses on composability, letting you chain agents, route tasks between specialists, and integrate with existing model providers and APIs. It fits naturally into Node.js and serverless environments, making it suitable for backend services, internal automation, and customer-facing AI features. Because it is code-first and unopinionated about UI, AgentKit is best suited to engineering teams comfortable working in TypeScript who want fine-grained control over how their agents reason, call tools, and handle long-running tasks.

Use it every day

Honestly didn't expect to like it this much. Agent and tool abstractions is exactly what I needed, and composable multi-agent orchestration. I do wish no built-in UI or no-code layer, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: agent and tool abstractions and composable multi-agent orchestration. On balance the feature set — especially state and memory management — justifies the 5 stars for our use case.
