One of the major differences between WordPress.com and WordPress.org is who hosts the website. i.e., in WordPress.org, a user can host their own blog or website.

But on WordPress.com, it takes care of all the hosting, meaning the user does not have to download software, manage a web server, or pay for hosting.

- WordPress.com has more limitations than WordPress.org.
- On WordPress.com, you do not own your content, but with WordPress.org, you do.
