eez.io can be used as a stand alone store or it can be integrated with any personal website or blog.
Out of the box eez.io gives you a stand alone store and an ability to sell outside of your store - for example you can sell directly from your website pages or blog, etc...
You also get unlimited sales/storage/bandwidth with your eez.io store account.
Please let me know if you have any farther questions
