What Superfeedr is

Superfeedr provides a feed API for applications that publish content, consume feeds, or monitor topics across feeds. It supports RSS, Atom, and JSON, and sends updates through push notifications and webhooks. Publishers can use hosted PubSubHubbub hubs to notify subscribers when content is added or changed; hubs include subscriber exports and analytics, with JSON export available. Pro Hubs add a custom CNAME, landing page, and control over subscriptions. Subscribers submit feed URLs and receive content as Atom or JSON. Trackers can filter mentions across millions of feeds using included or excluded terms, exact or fuzzy matching, and language filters. Subscriber use is pay as you go: fewer than 10 feeds in a month are free, and charges are based on the maximum number of feeds subscribed to in a 30-day period. Tracker plans cost $2.00 per month per tracking feed and include 2,000 monthly notifications per feed; regular subscriber pricing applies after that. Pro Hubs cost $200.00 per month. High-frequency feeds may still be polled as often as every minute.
