Duda lets you sell up to 10 products for free – for anything more, you have to pay an additional fee on top of your monthly subscription. With WordPress, you can install a plugin like WooCommerce for free (with the Business plan subscription or higher) and sell unlimited products, plus get access to better e-commerce features.  If neither Duda nor WordPress meet your specific needs and you want to review more options, check out our list of the best website builders for 2022.
