Written in optimized C++ where competitors use Python or Java, NZBGet saturates fast connections while idling on CPU and RAM - which is why the performance-obsessed Usenet downloader has long been the client of choice for NAS boxes, Raspberry Pis, and routers as much as full servers. The engineering shows in the recovery pipeline. Instead of shelling out to par2cmdline, NZBGet integrates the par2 source directly and exploits its knowledge of exactly which articles failed - quick par-verification checks only what needs checking, and its own multicore repair implementation runs 2-3x faster than the external tool on the same hardware. Fast par-rename deobfuscates scrambled filenames in seconds without a full verification pass, and rar-rename recovers names for multivolume archives even when no par2 files exist. DirectWrite assembles articles straight into sparse destination files, skipping temporary-file churn entirely, with an article cache and queue-pausing options to eliminate disk contention. Automation is complete: a remote web interface, full JSON-RPC API, RSS feeds with duplicate detection, scheduling and prioritization, and an extension manager for Python and Bash scripts triggered by download events. Sonarr, Radarr, and every major indexer integrate natively.

Find a title tonight and wake up to it named, filed, and ready to play: Mediarium is a self-hosted media manager that finds, downloads, repairs, and organizes movies, TV, music, ebooks, and audiobooks from one web page on your own server. Search once and it queries your Usenet and torrent indexers together, grabs the best release, unpacks it, applies your naming rules, and places it where Plex, Jellyfin, or Emby expects it. Quality profiles with upgrades and fallbacks keep hunting better copies automatically, while delay profiles, a blocklist with retries, and tags such as Kids or 4K keep the wrong releases out and collections tidy. Subtitles are matched to your exact file, with a timing fix when one runs out of sync. Family accounts carry permissions of their own: relatives who cannot add titles send requests you approve, and watch history read from your media server drives statistics and optional cleanup rules. The built-in Books app reads ebooks, plays audiobooks chapter by chapter, remembers your place everywhere, and even opens Kindle books. Torrents can run behind a built-in WireGuard VPN with a kill switch, downloads repair and unpack themselves, and notifications, backups, and a post-import script keep the routine invisible. Moving over reads your Radarr, Sonarr, Prowlarr, SABnzbd, and other existing setups without changing them.

Configure each indexer once, not five times: Prowlarr is the indexer hub of the *arr stack, removing the most tedious duplication in a media automation setup. Instead of configuring the same torrent trackers and Usenet indexers separately in Sonarr, Radarr, Lidarr, Readarr, and Mylar3, you add each one once in Prowlarr and it syncs them to every connected app automatically, complete with category mappings; with Full Sync enabled, adding or removing an indexer propagates everywhere, and a tracker URL change is a one-place fix. Coverage is the deepest available: 500+ torrent trackers with definitions added constantly, 24 native Usenet indexers, generic Newznab and Torznab support for anything else, and custom Cardigann YML definitions with JSON and XML parsing for obscure sources. Built on the same .NET/React base as its siblings, it also earns a place as a search tool in its own right: unified manual search queries every indexer simultaneously at a category level, and you can push multiple releases straight to your download clients without touching Sonarr or Radarr. Health checks and status notifications flag failing indexers, per-indexer statistics track success rates and response times so you can cull unreliable sources, and per-indexer proxy support (SOCKS4/5, HTTP, FlareSolverr) handles trackers behind Cloudflare.

The movie half of the *arr stack: Radarr is a .NET collection manager that automates acquiring films for Usenet and BitTorrent users the way Sonarr does for TV. Add a movie once and Radarr handles the rest: it monitors indexers and RSS feeds, grabs a matching release the moment one appears, sends it to SABnzbd, NZBGet, qBittorrent, Deluge, Transmission, rTorrent, or another connected download client, then imports, sorts, and renames the file into your library structure. Quality profiles are the control surface - define allowed resolutions and a cutoff, and Radarr keeps upgrading files automatically, replacing a DVD rip when a Blu-ray release lands. Custom formats go further, scoring releases by codec, HDR metadata, release group, streaming source, or arbitrary regex so the copy you want always wins the pick. Failed downloads retry with another release automatically; a manual search shows every candidate and explains why one was skipped. Release parsing recognizes director's cuts, special editions, AKA titles, and hardcoded subs. Plex and Kodi integration handles notifications, library refreshes, and metadata like posters, trailers, and subtitles, and a calendar view tracks upcoming releases. It pairs naturally with Jellyseerr for request management and shares its API conventions with the whole *arr ecosystem.

Add a series once, set a quality profile, and everything downstream is automated: Sonarr is the smart PVR for Usenet and BitTorrent users. It monitors RSS feeds from your indexers, detects new episodes the moment they release, sends matching grabs to SABnzbd, NZBGet, qBittorrent, Deluge, or another download client, then renames files with fully configurable templates, sorts them into consistent folder structures, and notifies Plex, Kodi, or Jellyfin to update the library. Quality profiles define what's acceptable (HDTV, WEB-DL, Blu-ray, up to 4K) and an upgrade cutoff - when a better release appears, Sonarr replaces the existing file automatically, stepping from HDTV to WEB-DL to Blu-ray until the cutoff is met. Custom formats add weighted scoring for finer-grained release selection, with community-maintained TRaSH Guides presets as the widely accepted defaults. Failed downloads are handled without intervention: Sonarr retries with another release, and manual search shows every candidate with the reasons any was rejected. It scans existing libraries for missing episodes, fully supports specials, multi-episode files, and daily and anime series types, and a calendar view shows upcoming episodes across every tracked show. Runs on Linux, Windows, macOS, and Raspberry Pi, and pairs naturally with Prowlarr for centralized indexer management.

Stalled torrents, malware-laced archives, and failed imports can quietly paralyze an automated media server, and Cleanuparr eliminates those bottlenecks as an autonomous download queue manager and library seeker for the entire Servarr ecosystem. Connecting directly to Sonarr, Radarr, Lidarr, Readarr, Whisparr, Sportarr, and LazyLibrarian alongside qBittorrent, Transmission, Deluge, rTorrent, uTorrent, and SABnzbd, its configurable Queue Cleaner tracks slow transfers, stuck metadata downloads, and import failures using a strike system. Once a problematic download reaches its strike threshold or triggers the Malware Blocker against deceptive .lnk and .zipx payloads, Cleanuparr purges the offending files, blocklists the release, and instructs the media manager to search for a clean replacement. Beyond defensive queue hygiene, the built-in Seeker proactively searches your libraries for missing episodes or movies, hunts for Cutoff Unmet quality upgrades, and tracks Custom Format score distributions over time. Storage administrators can also enforce seeding duration limits, clean up orphaned torrents without breaking active cross-seed hardlinks, and quarantine unclaimed directory files before they consume disk capacity. A live web dashboard visualizes manual intervention alerts, strike histories, and searchable application logs while dispatching instant notifications through Apprise, Discord, Gotify, Notifiarr, Ntfy, Pushover, and Telegram.

Stop wrestling with dead scrapers and scattered reading folders by orchestrating your digital library through Bindery, an automated ebook and audiobook management platform that tracks favorite authors, monitors release schedules, coordinates indexer searches, and organizes media collections. Users can configure monitoring profiles to automatically track author bibliographies across OpenLibrary, Google Books, and Hardcover without fear of dead endpoints breaking their library. Dual-format tracking allows each book entry to hold separate digital ebook and multi-part audiobook files in distinct directory roots. The integrated search engine evaluates Newznab and Torznab indexers in parallel, scoring releases by edition tags, audio bitrate, narrator names, and release year to grab the highest quality versions. Download jobs pass seamlessly to background clients like SABnzbd, NZBGet, Transmission, or Deluge, moving completed files into custom library folder structures with hardlinks. An interactive release calendar highlights upcoming publications, while the manual metadata editor locks custom titles, genres, and series ordering against upstream refreshes. Readers can browse curated collections directly through the built-in OPDS feed on mobile reading apps or export organized media straight into Calibre and Audiobookshelf.

When household readers want a single web portal to search, request, and deliver ebooks and audiobooks without juggling separate indexers or download clients, Shelfmark unifies the entire acquisition pipeline in one self-hosted hub. Universal search mode queries Hardcover, Open Library, and Google Books for rich cover art, series order, and edition metadata before aggregating matching releases across every configured source. Direct search mode queries individual providers immediately for rapid title lookups. You can connect Prowlarr torrent and Usenet indexers, direct web download mirrors, IRC book channels, and Soulseek peers through slskd inside one unified interface. Multi-user accounts support granular request policies where family members or friends submit book or release requests for admin approval, complete with per-user language preferences and custom delivery targets. Completed downloads automatically rename and route files into Calibre, Calibre-Web, Grimmory, BookLore, or Audiobookshelf watch folders, or dispatch directly to e-readers over SMTP email. Built-in authentication supports local credentials, reverse proxy headers, OpenID Connect single sign-on, and existing Calibre-Web user databases. Optional WireGuard VPN with a fail-closed kill switch and Tor routing keep external indexer queries private.
