An OPML browser is a tool that lets you manage and view collections of RSS feeds, usually saved in the OPML file format. Instead of adding feeds one by one, you can load a whole list at once—like a playlist for news, blogs, or podcasts. It's handy for following many sources or sharing your feed subscription set with others.
