Quick Start
make docker-upDetailed Introduction
This project offers a robust, production-ready FastAPI template specifically designed for developing AI agent backends using LangGraph. It abstracts away complex infrastructure concerns such as stateful conversations, long-term memory, tool calling, observability, authentication, and rate limiting. Aimed at AI engineers, it provides a solid foundation, enabling them to concentrate solely on agent logic rather than boilerplate setup. This template ensures scalability, security, and maintainability for sophisticated AI applications.
