Yes, WordPress is a free and open-source content management system (CMS) that you can use to create and manage a website. You can download and use WordPress free, with no time limits or expiration dates.
However, while the WordPress software is free, you will need to pay for other expenses such as web hosting, a domain name, and potentially premium themes or plugins. These costs can vary depending on your needs and budget, but they are separate from WordPress software and are not required for the basic functionality of a WordPress website.
