rss-Bridge has decent caching support, customisable on a bridge level, so that comes pre-tuned and works well at low volumes for personal use.

At large scale, like the kind of traffic I started seeing when I ran a public rss-bridge Instagram/Telegram bridge - rate limits are unavoidable.

That's been my experience too. Some of the bridges take into account the rate limits imposed by the platforms, and the steps required to get content without an API key.

So using RSS Bridge to generate feeds from large platforms is often a lot more reliable than the typical scraping script I'd code up myself for other sites.
