Etsy is an online marketplace for handmade and vintage items. It is a popular destination for crafters to sell their products, and is often referred to as a 'crafter's online outlet'. Etsy was founded in 2005 and has since become one of the most successful e-commerce websites in the world. It provides a platform for crafters to showcase and sell their unique creations, allowing them to reach a larger audience than they would be able to through traditional retail outlets.
