useAgent is a React hook designed to simplify the development of real-time, multi-step, and multi-agent backend workflows, enabling seamless integration with front-end user interfaces. It addresses three primary challenges in building such systems: ensuring durable workflows that can recover from failures, providing comprehensive observability for debugging complex agent behaviors, and streaming real-time experiences without extensive infrastructure management. Traditional approaches, like building custom solutions or using general agent frameworks such as LangGraph or Vercel AI SDK, often require significant setup time and lack complete features like durability and built-in observability. useAgent, built on Inngest's infrastructure, offers automatic retries and fault tolerance, composable streaming parts for real-time updates, and comprehensive debugging tools, all with minimal setup, allowing developers to focus on creating polished AI-powered workflows quickly.
