## What it is
Mall4j is an open-source Java e-commerce mall system built on Spring Boot 4, Vue3, Sa-Token, MyBatis-Plus, and Redis, providing product, order, member, SKU, cart, payment, and admin management for B2C single-merchant stores. The open-source edition is AGPLv3-licensed for learning, evaluation, and compliant use, with commercial editions covering multi-merchant, SaaS, and cross-border scenarios.

## Use cases
- build a self-hosted java online store
- open source b2c mall system source code
- spring boot vue3 ecommerce platform
- learn how a shopping mall backend works
- prototype an online shop with sku and cart
- evaluate java mall systems for a business
- base code for customizing an e-commerce site

## When to choose
- you need a full-featured B2C single-merchant store with admin backend
- you want a modern Spring Boot 4 + Vue3 stack to study or extend
- your use is AGPL-compatible (learning, evaluation, open-source deployment)
- you plan to self-host and customize the storefront

## When to avoid
- you need closed-source commercial use without buying a license (AGPLv3 applies)
- you need multi-merchant, SaaS, supply-chain, or cross-border features out of the box (commercial editions only)
- you want a hosted SaaS solution rather than self-hosted source code
- you are not comfortable with Java/Vue full-stack development
