It is widely adopted with over 1.4 million developers globally, catering to both indie developers and large enterprises due to its versatility and extensive functionalities. Xamarin is employed across various domains, including gaming, where its platform was used to develop mobile versions of popular games like "Transistor" and "Skulls of the Shogun," achieving recognition such as Apple's App Store Editor's Choice. Other applications leveraging Xamarin range from Storyo's collaborative video storytelling app and JustGiving's fundraising platform to the Alaska Airlines travel app, OLO's food ordering service, and Insightly's CRM tool.
