Generating product feeds URL in Magento

I would like to know if Magento has any native product feeds generator (I mean in the backend). I need the feeds to be generated in a URL, not physical files, since they will be automatically called every hour. Shopware has a product feeds section, this is why I am wodering about Magento.

In case there is no such option, I was searching for any free extension or extensions which would do it correctly, but couldn’t find any.

The feeds are needed for Google Merchant, Facebook Ads and Belboon.
