If you use WordPress.com, you can create a site without installing anything. If you use WordPress.org (self-hosted WordPress), you must install it on a web host or on your computer (localhost) to use it. Most businesses prefer WordPress.org for full control and plugin/theme flexibility.

Install a local server (XAMPP/WAMP/MAMP/LocalWP). Start Apache + MySQL. Put WordPress files inside the local web directory (like htdocs). Create a MySQL database in phpMyAdmin. Open http://localhost/foldername and follow the WordPress setup wizard. After installation, log in at http://localhost/foldername/wp-admin.

Install XAMPP, start Apache and MySQL. Download WordPress and extract it into:Windows: C:\xampp\htdocs\your-site-folder\Create a database in http://localhost/phpmyadmin. Then open http://localhost/your-site-folder to run the installer. Use DB name you created, username usually root, password usually blank (unless you set one).

Yes. WordPress software is free to download and use. You can install it on your computer using a local server (XAMPP/WAMP/MAMP) or a tool like LocalWP. The only costs come when you want a live website: domain name and hosting (and optional premium themes/plugins).

Usually yes—each domain needs its own WordPress installation if you want separate websites. However, you can run WordPress Multisite to manage multiple sites from one WordPress install, or use subdomains/subfolders depending on your plan. If each domain is a separate project, separate installs are simpler to manage.

Install a local server tool like XAMPP/WAMP/MAMP or use LocalWP (simplest). Start Apache + MySQL, create a database, copy WordPress files into the local web folder, then open localhost/your-folder in a browser. Enter database name, username, and password, then complete the WordPress setup and log in.

Go to WordPress.org and download the WordPress ZIP file. Extract it on your computer. If you want it to “run” locally, you also need a local server (XAMPP, WAMP, MAMP, or LocalWP). Then place the WordPress files in the server web folder, create a database, and run the installer in your browser.
