Add SpaceXplorer to the list of known apps
Hi, I made a SpaceX launch tracker web application under the name: SpaceXplorer.

The app gives you an ability to search for launches and filter them on [/search](https://space-xplorer.vercel.app/search) page and inspect every single launch via a dynamic url: `/launches/{id}`.

Index page also has a countdown for the next upcoming launch.

Source code is available on the [GitHub Repo](https://github.com/pavles6/SpaceXplorer) of this project.

App is currently hosted on https://space-xplorer.vercel.app/

Thanks for maintaining this amazing API! 🚀
