itch.io gives you the ability to design a page where people can download games you have uploaded. You can optionally put a minimum price on your game (which can be 0), giving people the opportunity to pay you what they think you deserve. All files and images are hosted on itch.io so you don’t need to worry about building a website or storing your game anywhere.
Usage information is collected and displayed to you, such as how many times your games are being viewed, downloaded, and purchased.
itch.io handles all the technicalities behind hosting and selling your game.
