How can you view a rss web feed instantly?

To view an RSS web feed instantly, you can use a web browser that supports RSS feeds, such as Firefox, which can automatically detect and display them. Alternatively, you can use an RSS reader app or service like Feedly or Inoreader; simply paste the feed URL into the app to subscribe and view the content. Many websites also offer "Subscribe" buttons that allow you to add their RSS feed directly to your preferred reader.
