提到开源，一定绕不开Linux。Linux 是一款开源软件，我们可以随意浏览和修改它的源代码，学习 Linux，不得不谈到开源精神。Linux 本身就是开源精神的受益者，它几乎是全球最大的开源软件。
用户具有使用自由、修改自由、重新发布自由和创建衍生品自由，这正好符合了黑客和极客对自由的追求，因此开源软件在国内外都有着很高的人气，大家聚集在开源社区，共同推动开源软件的进步。
那么今天介绍的这一款软件及时如此，首先他们的开源性毋庸置疑，所有版本的代码都是无加密，免费版本、商业版本都是可以商用的！而这个对于初创企业不要太好，商业模式不清楚的情况下，小步试错，初有成就之后买个商业版本，把商业版图扩大！

另外，商业版本提供的各种文档是真的很齐全，因为涉及到相关协定，商业版本不能发了，但是有几个点可以透露下：开源无加密、多店铺入驻、技术免费售后、永久授权、永久免费更新……这些关键词全部满足的源码，在3万以内的预算的，应该找不到第二家。当然有小伙伴会拿着部分需求来对比，记住哈，全部满足的情况下，而且项目稳定迭代3年，这样的源码即便是PHP也不会低于3万的。
