This service monitors undocumented event kinds in the Nostr network, aiding developers and researchers who are looking to introduce new kinds without clashing with others. For programmatic access, use the JSON endpoint.
The tracker not only helps avoid clashes but also provides insights into the evolving use of the network, revealing emerging trends and creative concepts before they're formalized in NIPs.
Note: Kinds not observed for a month are removed from the list.
