Fly.io is a new public cloud platform designed for running applications near users, ensuring faster performance. The platform has made improvements to its launch process, making it easier and more streamlined. When using the `fly launch` command, the CLI now infers settings based on an application's source code, providing default options or allowing users to modify them if necessary. Once confirmed, the app is built and deployed, with a link provided for users to check it out. Fly.io encourages feedback from its community to further improve the platform.
