I built followww. to help my online marketeer colleagues get insights in what is hiding behind short URLs. Before building this tool, they routinely came to me with URLs asking me to trace them.
The back-end is a websocket API that returns each step as it discovers it and the front-end is an Angular (1.x) application. I also built a small Chrome extension (https://chrome.google.com/websto...) that adds a followww. context menu item to all links on the web.
