Cardigann vs Prowlarr

Cardigann is an open-source web scraper that is designed specifically for indexing and searching torrent files from various public torrent sites. It acts as a proxy between the user and torrent sites, allowing searching and downloading of torrents without having to visit the actual sites.

Prowlarr is a free, open source alternative to paid usenet indexers like NZBgeek and NZBFinder. It aggregates RSS feeds from usenet indexers and provides a unified interface to search and access releases across multiple indexers.
