Automating media server storage reclamation, Maintainerr is an open-source library maintenance platform that identifies unwatched, abandoned, or stale movies and shows across Plex, Jellyfin, and Emby and clears them on a schedule. Storage drives fill up rapidly when household members request four-season series or high-bitrate films, watch a single episode, and abandon the rest indefinitely. Instead of forcing administrators to audit disks by hand, the rule engine evaluates metadata from your media server alongside Tautulli watch histories, Seerr and Ombi request records, and Radarr, Sonarr, or Sportarr profiles every eight hours. Matching items enter a staging collection that syncs back to your media server home screen as a Leaving Soon row, complete with dynamic poster overlays displaying the exact removal date so viewers have a grace period to finish watching. Before enabling any destructive workflow, you can run the Test Media inspector against any movie or episode to preview rule evaluations and protect favorites with global or per-collection exclusions. Once the countdown expires, the collection handler deletes or unmonitors files, updates import-list exclusions so automated lists never re-download removed titles, clears orphaned requests in Seerr and Ombi, removes leftover sidecar folders, and dispatches alerts through Discord, Slack, Telegram, Pushover, Gotify, Email, or webhooks.

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.

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.

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.

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.

Subtitles are the one chore Sonarr and Radarr leave behind - Bazarr finishes the *arr media stack by automating them. It connects to both via their APIs and mirrors their libraries - it doesn't scan disk itself, it manages exactly what your *arr apps index. For every monitored episode and movie it checks existing internal and external subtitles against your language profiles, then hunts missing ones across dozens of providers - OpenSubtitles.com, Podnapisi, Addic7ed, Subscene, and many regional sources - covering 184 subtitle languages including forced/foreign-dialogue tracks. Matching is smarter than filename guessing: releases are compared by release group and source, some providers support exact file-hash matching, and every downloaded subtitle gets a percentage score. Set a minimum score per Sonarr/Radarr connection and Bazarr rejects weak matches; enable upgrades and it replaces previously downloaded subtitles when better ones surface. Out-of-sync files get fixed too - automatic subtitle synchronization realigns timing after download, triggered only below a configurable score threshold so good subs aren't touched. Per-show and per-movie language configuration, download history, manual on-demand search, and adaptive searching that throttles provider API calls round it out, all behind a clean Sonarr-style web UI written in Python. If your library serves multilingual viewers, this removes the last manual step.

Profilarr orchestrates media library quality profiles, custom formats, and release matching rules across all your Radarr and Sonarr servers from a single centralized management console. Instead of manually copying regex strings and scoring tables between home server instances, you can link community configuration databases like TRaSH Guides and Dictionarry to automate standardization. The visual pattern workbench lets you test regular expressions directly against real-world media release titles, highlighting matches for audio codecs, HDR formats, and release group tags. You can simulate release scoring before deploying, inspecting exactly why a candidate download gets accepted or rejected based on your custom ranking conditions. Media managers can define custom delay profiles, establishing protocol priorities and minimum score thresholds to prevent premature grabs before high-quality releases surface. Granular synchronization tools push updated profiles and formatting rules to multiple production Arr instances simultaneously while preserving your local server overrides. When indexers publish new release naming conventions, you can update conditions once in your central database and roll out updates across your entire infrastructure.

Browse trending titles, search anything, request it in two clicks: Jellyseerr gives Jellyfin, Emby, and Plex users a beautiful storefront for the media library. Born as the Overseerr fork that added Jellyfin and Emby support (the projects have since unified as Seerr), it handles the full request lifecycle - users authenticate with their existing media-server accounts, pick individual seasons or movies in a clean interface, and admins approve or decline from a simple queue, including on mobile. Approved requests flow straight to Sonarr and Radarr, which handle acquisition automatically, with support for separate 4K server instances. Regular library scans keep availability accurate, so users see instantly what already exists instead of requesting duplicates. A granular permission system controls who can request what - auto-approval for trusted users, quotas and limits elsewhere - and override rules adjust request routing by user, tag, or other conditions. Watchlist and blocklist functions curate discovery, notifications reach email, Discord, Telegram, Slack, Pushover, and Pushbullet, and both PostgreSQL and SQLite are supported. Localized into many languages, it turns "can you add this movie?" texts into a self-service system that runs itself.

Jellystat is a self-hosted media analytics and live session monitoring dashboard for Jellyfin and Emby servers that turns raw streaming activity into detailed user, library, and playback insights. Media server administrators use the live dashboard to watch active streams in real time, inspecting transcoding status, client devices, bitrates, and playback progress as sessions happen. Every completed or partial stream is logged automatically so you can browse chronological watch histories, filter by library or stream type, and analyze peak concurrent streaming hours across the week. Dedicated library and user views break down total watch duration, play counts, and most popular movies, episodes, or music albums per account. If you already use the official Jellyfin Playback Reporting or Statistics plugins, you can import existing historical records directly into your instance without losing past data. Built-in database backup and restore tools, automatic library synchronization tasks, IP geolocation via MaxMind GeoLite, and interactive Swagger API documentation at the /swagger endpoint round out the administrative toolkit.

Does your container fleet silently fall behind on upstream patches until a critical vulnerability advisory forces an emergency audit? What's Up Docker continuously watches standalone Docker daemons, Compose stacks, Swarm services, Kubernetes workloads, and Nomad jobs to detect new image tags across public and private registries before sending alerts or rolling out updates automatically. Watchers connect over local sockets, TLS-secured TCP endpoints, kubeconfigs, or Nomad APIs to inventory active workloads without invasive sidecars. From there, registry connectors authenticate against Docker Hub, GitHub Container Registry, AWS ECR, Google Artifact Registry, Azure Container Registry, Quay, GitLab, Gitea, Forgejo, and self-hosted OCI registries to compare digests and tags. Flexible filtering rules let you restrict alerts to major, minor, or patch semantic version increments, match custom regular expressions, or pin specific tag patterns per container label. Once an eligible release appears, over thirty built-in triggers can dispatch notifications to Discord, Slack, Telegram, Matrix, Mattermost, Gotify, Ntfy, Pushover, Apprise, PagerDuty, or SMTP, publish events to MQTT, Kafka, RabbitMQ, or NATS, or recreate containers directly on demand. A responsive web dashboard and REST API provide manual update controls, OpenID Connect single sign-on with role-based access control, and Prometheus metrics for Grafana observability.
