One option is running changedetection.io on your server, it works for basically anything since it's actually loading a full web page and checking for changes.
Nice since it seems like everything these days requires apis and all kinds of BS to use in an app.
What plugin is it? Been using Obsidian as well since it's the best replacement I've found that also has easy self hosted syncing (Remotely plugin via WebDAV)
Sure, it's no different than an internal SSD.
