Jackett
Jackett works as a proxy server: it translates queries from apps (Sonarr Radarr SickChill CouchPotato DuckieTV etc) into tracker-site-specific http queries, parses the html response, then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic - removing the burden from other apps. Developer note: The software implements the Torznab (with nZEDb category numbering) and TorrentPotato APIs.
