RSS Overview#

With the RSS API you have the power to create powerful tools and applications.
RSS is a great way to reliably subscribe to, track and build around your
favorite content sources. Here are some examples of things you can create
using the RSS API:

A personal news website to syndicate articles from multiple sources.
A custom feed reader to deliver timely notifications of updates and news.
A live editorial dashboard to track news, trends and public sentiment.
An automated “report bot” to aggregate and report on news topics.
A competitor tracking tool to stay on top of industry news.
A custom RSS-based search engine or RSS-supported deep learning engine.
A live events feed to notify users and followers of new developments.

Browserless Overview#

Browserless allows you to build websites and applications that can be used
without a web browser. This means that you can create apps that can be used
offline, or that can be used on devices that don't have a web browser
installed.

Some examples of things that you can build using Browserless are:

A website that can be used without a web browser
An app that can be used offline
A app that can be used on devices that don't have a web browser installed
