atomstr converts RSS and Atom feeds into Nostr events by fetching feed content and publishing it through the protocol.
About atomstr
atomstr fetches RSS and Atom feeds and publishes new entries as Nostr events to configured relays, creating a separate Nostr profile for each feed.
It provides a web portal and command-line commands to add, list and delete feeds, with parallel fetching, NIP-05 verification, NIP-48 support and tracking of feed failures. Self-hosting with Docker is the preferred setup, and the public test instance is not intended for heavy use.

atomstr FAQ
How do I add a feed?
Use the web portal, or run docker exec -it atomstr ./atomstr -a https://my.feed.org/rss on the host.
How can I follow these feeds in Nostr?
Add a relay the server publishes to in your profile, then find and subscribe to the feed profiles. The default publish relay is wss://nostr.data.haus.
What happens when a feed breaks?
After 3 consecutive failures by default it is marked broken and retried every 24 hours. It is restored if it works again and removed after 100 consecutive failures.
