Stop building AI Agents from scratch: I open-sourced my production FastAPI + LangChain stack

说明与用途

该框架通过消除重复的 FastAPI 和 LangChain 设置，简化 AI 代理开发，支持在不到 5 分钟内本地启动。

问题

Developers repeatedly had to manually set up backend infrastructure, configure LangChain Expression Language pipelines, and mock Stripe webhooks for each new AI automation project, leading to wasted time and inconsistent codebases.

结果

The boilerplate reduces setup time by over 40 hours, standardizes project structure, and enables rapid prototyping of AI agents for B2B agencies and indie developers.

工作流

• Clone the repository from GitHub
• Install dependencies via pip or poetry
• Configure environment variables (e.g., API keys, Stripe secrets)
• Run the FastAPI server locally
• Use the provided LCEL pipeline templates to build AI agent logic
• Test endpoints with Postman or curl
• Deploy to production when ready

证据

I cleaned up my backend code structure and open-sourced it as an ultra-lightweight, production-ready framework blueprint for indie developers and B2B AI Automation Agencies (AAA).
