I made an interactive Drake Equation back in 2007, it is embedded in this page: https://www.damninteresting.com/space-radio-more-static-less...

It's not mobile-friendly, unfortunately. I made it in the same year the first iPhone was released. Some day I'll update it for smaller viewports. Some of the default settings are also too low, for example we now know that exoplanets are very common.

Edit: Oh yes, it slipped my mind that there is a totally stand-alone version here: http://astro.nomical.info/drake/
