I would be more interessted in a ready-to-use server which I can selfhost and to which I can throw any script for collecting data, filter and process them, which also handles errors and storage. At the moment the only real solution for this seems to be using your own RSS-Reader (Tiny Tiny RSS for me at the moment), which has the disadvantage of being limited to RSS-sources, as also not allowing much filtering and processing. But with more and more sources moving avway from RSS, I want something which can be fetch alternative sources and integrate them into a unified interface. In best case it would be even work with any language, be it a shellscript or python, ruby or even java.
