Heyas, wondering if there's an open sourced piece of software or the like, that could scrape media platforms for a specific topic. Platforms like YT, X, Lemmy, News Media, etc., perhaps using RSS? But, a program I can host on my server, that only I have access too, via webpage, CLI, whatever...
Seconding the recommendation for FreshRSS, it's the one I ended up hosting when I looked into this a while back and it's been really great. Takes a minute to get everything setup, especially if you want to have different settings for different types of feeds, but once it's all set it's perfect (for my needs at least).
I've also got it setup with my domain so I can access the feed from anywhere and that's been one of my favourite features.
