Jeepay: An Open‑Source Payment System for Internet Enterprises

Project Introduction

Jeepay is an open‑source payment system designed for internet enterprises, supporting multiple channel service providers and ordinary merchant modes. It integrates official APIs for WeChat Pay, Alipay and Cloud QuickPass, and offers aggregated QR‑code payments.

It is built with Spring Boot and Ant Design Vue, incorporates Spring Security for permission management, and serves as a practical web‑development framework.

Name Origin

Jeepay = Jee + pay; “Jee” represents the company Jiquan Technology, and “pay” denotes payment, reflecting the goal of safe and convenient payments.
