FreshRSS is a really great web-based program for Windows that reads your RSS feeds, and is a full feature aggraget program to host all your feed data yourself, on your own device. Your data is your own, and you do not have to rely on other people. FreshRSS makes it easy to organize all your data also. The speed is incredibly fast, and even more responsive.
FreshRSS can manage hundreds of thousands of articles without any trouble at all. It is also impressed with how fast it can manage all your feeds, and pull up all the data. The website is comprehensive, with all the information in an easy-to-find place, as well as the link to be able to download this software. It's almost hard to believe how great this is, and for free also. Many other programs like FreshRSS charge you a premium to do almost the same thing FreshRSS does, but FreshRSS doesn't charge you a thing... That's right, it's totally free, and even has better features than the other programs out there that do charge you.
I should mention that they are really easy to get into contact with, and gladly help with anything you need regarding the program (they are very friendly too). FreshRSS has a really modern-looking interface and is easy to plug your data (your feeds) into. It really helps to be able to get all the important information off a webpage without having to always check for updated articles all the time. It's great for reading your feeds without having to wade through all the normal things that litter a webpage like ads, and pop-ups all the time. The bullet points of the best features are outlined below.
Give it a shot, FreshRSS is free so no regrets.
