WordPress's basic version comes with a free plan that allows you to build your website without hosting. It gives you the option of creating a website for your brand without paying for hosting. You can even set up your website without a domain name on WordPress.
WordPress.com is similar to a site like Typepad, or even Tumblr. Instead of having your site on your own domain, you'll create a free site on a subdomain. So people will have to type in something like “yourname.wordpress.com” to access your site. With this, you don't have to worry about a domain or hosting.
