Superfeedr
What it is
Superfeedr provides a unified API for RSS, Atom, and JSON feeds, delivering updates through real-time notifications and webhooks. Publishers can use PubSubHubbub hubs to alert subscribers about new or changed content, export subscriber information, and view analytics with counts, timeframes, and JSON export. Pro Hubs add custom CNAMEs, landing pages, and subscription controls. Subscribers submit feed URLs and receive Atom or JSON data through webhooks. Tracker users can monitor mentions across millions of feeds with included or excluded terms, exact or fuzzy matching, and language filters. The service uses PubSubHubbub and RSSCloud, while updates may still be polled as often as every minute for high-frequency feeds. Fewer than 10 subscribed feeds in a month are free. Tracker costs $2.00 per month per feed with 2,000 notifications included; Pro Hub costs $200.00 per month.
