DIYgod/RSSHub ? reverse-engineered prompt

Build me an open source service that can turn almost any website or social platform into an RSS feed, similar to RSSHub. I want people to paste or visit a simple route URL for a source, like a creator, topic, channel, profile, or search page, and get back a clean RSS feed they can subscribe to in any reader.

It should support lots of different sources over time, including common platforms like YouTube, Bilibili, Twitter, TikTok, Instagram, Weibo, Zhihu, Douban, Spotify, Telegram, and similar sites. Make it easy for contributors to add new feed routes without touching the whole app.

Please include a simple homepage that explains what the service does, links to documentation, and shows how to use a route. It should be possible to run locally and also deploy as a public instance, ideally with a container option. Keep the feeds reliable, readable, and compatible with modern RSS readers like Folo.

Look up current RSSHub style docs online if you need to.
