Rokkit is a URL shortener built with Laravel and Livewire. It allows users to create shortened URLs that redirect like a regular link redirect, or a user can opt to create an advertisement during that redirect. Here is a demo of an advertising redirect.
Rokkit is hosted on a Cloudways managed DigitalOcean droplet, and uses the Cloudways API to add domains to SSL certs for custom domains. A more detailed look into this can be found here.
