I built a way to track people when they guest appear on podcasts

You can add the RSS feed to any podcast app you want and it will automatically update whenever they appear on a new one

Nice. How are you syncing and deduping the data? The page says it uses an API but doesn't go into detail of which. Is there storage and caching implemented?

Yep, the basic flow is a query of the taddy api https://taddy.org/developers/podcast-api

Then I host everything on a firebase service where I store all data and serve it up quickly.

There are some small problems with de-duping when a podcast gets uploaded on multiple feeds, but I haven't found a great way to handle that besides comparing the titles/descriptions
