Can I use Recipe Card Blocks on WordPress.com?
Yes.
Our plugin works on self-hosted WordPress websites (WordPress.org), and also on WordPress.com.
Please note that if you use WordPress.com, you will need a Business or eCommerce Plan to install our themes.
If you're looking for good WordPress hosting, we highly recommend starting with SiteGround.
