WordPress的
WordPress (WordPress.org) 是一个免费的开源内容管理系统 (CMS),用 PHP 编写,并与 MySQL 或 MariaDB 数据库配对。功能包括插件架构和模板系统,在 WordPress 中称为主题。 WordPress 最初是作为博客发布系统创建的,但现已发展为支持其他类型的 Web 内容,包括更传统的邮件列表和论坛、媒体库、会员网站、学习管理系统 (LMS) 和在线商店。
I use Wordpress a while now and it is completely trade-free, since you don’t have to pay any money, nor data, nor anything else. Some plugins or themes for Wordpress are not trade-free! But Wordpress itself is. Also, don’t confuse it with wordpress.com – that’s different. You can create a website on wordpress.com for “free”, but not trade-free. You can only choose a domain with yourdomain.wordpress.com and you have a lot limitations: https://wordpress.com/pricing/?ref=create-blog-lp therefore they want to sell you their personal, premium, business or commercial plan. So keep in mind, wordpress.com is not trade-free, but wordpress.org, the software, the content management system is trade-free.
