I’ve been running FreshRSS for several years now without any problems, but mine is running on a dedicated home server running other services too.
Your experience will depend on your RSS client. As others already mentioned, you will want to configure your client to only pull manually (usually on open only), otherwise it will keep throwing errors at you.
I am going to second the recommendation to get your hands on a cheap Raspberry Pi (you can easily run it on a Zero 2 W) with an 8GB microSD. You can then get a cheap US$2/year domain and use Cloudflare Tunnel to access it from anywhere without having to open ports or expose your whole network to the internet.
The full setup should be around $50 including the Pi, case, microSD, cable, power adapter, and cheap domain in NameCheap or similar.
Agree here too. FreshRSS is an RSS aggregator, basically a self-hosted GReader, which means it fetches the item contents and syncs the read status across clients. That is the HUGE advantage of using it instead of just adding the feeds directly to your client in your device.
Other FreshRSS features I love are the option to load full content of item that only share excerpts, and the option to use CSS selectors to remove content you don’t want (like embedded ads).
