The Plex Pass price hike to $750 lifetime is the loudest self-hosting story of the month, and the read-through is consistent: long-time Plex users are doubling down on the open-source companion stack that turns a Plex server from a media player into a full home library. These are the seven desktop companion apps that earn shelf space next to a Plex install in 2026.
The picks cover server analytics, request management, the music client most Plex users underrate, two media automation tools that handle ingest, transcode optimization, and the metadata curator that fixes posters and adds collections.
What to look for in a Plex companion app
The space is open-source first, so the things that matter are:
- Headless friendliness. Most run on the same machine as Plex or in Docker; the desktop story is the dashboard.
- Plex API integration depth. Some only read; some write back metadata, collections, and library state.
- Single sign-on. Plex auth flows into the better-built tools.
- Maintenance burden. Some are set-and-forget; some demand monthly attention.
- Container image. Most ship as containers; the well-maintained ones publish AMD64 and ARM64.
- Community. Reddit’s r/PleX and r/selfhosted are the support layer that keeps the ecosystem alive.

1. Tautulli — best for server stats and notifications
Tautulli is the Plex server companion that surfaces what your Plex server actually does. Watch history per user, top users by hour, libraries by play count, transcoding load over time. Notification rules fire on stream starts, server downtime, library updates, and new content additions. Most Plex admins install it on day one.
Where it falls short: Web-only interface — no native desktop client. The dashboard graphs feel dated, though the data behind them is fully exportable.
Pricing:
- Free: Fully free, GPLv3
Platforms: Windows, macOS, Linux (runs as a service or container)
Download: tautulli.com
Bottom line: First install after Plex itself for any admin who wants to see what’s happening on their server.
2. Overseerr — best for request management for households
Overseerr is the request portal you put in front of Plex so housemates and family stop texting you for movie additions. Users browse a TMDB-powered catalogue, request titles, and approved requests pass straight to Sonarr or Radarr for automated download. Plex auth means no new accounts; Plex profiles map to permissions.
Where it falls short: Depends on Sonarr and Radarr for the back end — Overseerr alone doesn’t pull media. Active development continues but cadence has slowed in favor of the Jellyseerr fork.
Pricing:
- Free: Fully free, MIT licensed
Platforms: Linux (container is the primary install); Windows and macOS via Docker Desktop
Download: overseerr.dev
Bottom line: The piece that turns Plex from a personal library into a family-shared one.
3. Plexamp — best Plex music client
Plexamp is Plex’s own desktop music client and the strongest reason to keep music in a Plex library at all. Sonic Sage and Sonic Adventure build automatic mixes from your library that read more like a paid music service than a local player. Loudness leveling, gapless playback, and full lyrics integration close the gap with the streaming services.
Where it falls short: Plex Pass account required. Personal music libraries with poor tagging produce poor mixes — the tool is only as good as the library underneath.
Pricing:
- Free: None (Plex Pass tier required)
- Paid: Included with Plex Pass
Platforms: Windows, macOS, Linux
Download: plexamp.com
Bottom line: The pick for Plex users who put real time into their music library and want it back as a personalized listening experience.
4. Sonarr — best TV show automation
Sonarr is the long-running automation tool for television libraries. It tracks the airing schedule per series, monitors indexers for new releases at the quality you specify, hands the file to a download client, and renames-and-moves the result into the Plex library. The 2025 v4 release brought a faster Postgres backend and a cleaner indexer config flow.
Where it falls short: Initial setup spans Sonarr, indexers, a download client, and Plex — first install can take an evening to get right. The UI is functional and not modern.
Pricing:
- Free: Fully free, GPLv3
Platforms: Windows, macOS, Linux (container is the common deploy)
Download: sonarr.tv
Bottom line: The TV piece of the *arr stack; pair with Radarr below.
5. Radarr — best movie automation
Radarr is Sonarr’s movie sibling, with the same shape and the same indexer-download-rename pipeline. Quality profiles let you set “I want this in 1080p remux” or “I’ll take 720p WEB” per movie. List management pulls titles from Trakt, IMDb, or a Letterboxd watchlist and queues them for download automatically.
Where it falls short: Same setup tax as Sonarr — the *arr stack rewards an evening of config. The default quality profile usually needs tuning to your library standards.
Pricing:
- Free: Fully free, GPLv3
Platforms: Windows, macOS, Linux (container is the common deploy)
Download: radarr.video
Bottom line: The movie counterpart most Plex admins install the same week as Sonarr.
6. Tdarr — best transcode optimization
Tdarr is the background worker that re-encodes your library to a standard you set. The most common use is collapsing a mixed library of H.264 and HEVC into a single codec at a target bitrate so Plex transcodes less under load. The node and server split lets you point spare desktop hardware at the job from another room.
Where it falls short: Encoding is CPU-heavy unless you have a GPU node. Wrong plugin choice can quietly shrink quality — test on a small library first.
Pricing:
- Free: Free for personal use
- Paid: Tdarr Pro license for the larger node fleets
Platforms: Windows, macOS, Linux
Download: tdarr.io
Bottom line: The pick for Plex admins whose server transcodes too often and whose storage isn’t growing as fast as the library.
7. Kometa — best for metadata, posters, and collections
Kometa is the renamed Plex Meta Manager — the tool that automates posters, collections, and per-library metadata refresh from YAML config files. Define a “Best of 2026” collection, point the config at IMDb’s list, and Kometa builds the collection in Plex with curated artwork. Trakt, TMDB, MDBList, and Letterboxd sources are all native.
Where it falls short: Config is YAML, learning curve is real, and the rename from Plex Meta Manager confused longtime users. Initial library refresh can run for hours.
Pricing:
- Free: Fully free, GPLv3
Platforms: Linux (container is the primary install); Windows and macOS via Docker Desktop
Download: kometa.wiki
Bottom line: The pick for admins who care about the way their Plex looks, not only what’s in it.

FAQ
What is the best free Plex companion app? Tautulli for stats, Overseerr for requests, Sonarr and Radarr for automation, FreshRSS-style self-hosting on a small home server. All are free and open source.
Is the Plex Pass price hike worth paying? The single $750 lifetime tier is a hard sell for most casual users. Monthly and annual Plex Pass tiers still exist, and several of the companion tools above (Tautulli, the *arr stack) deliver most of the value without paying.
Do these apps run on a Raspberry Pi? Most do. Tautulli, Overseerr, Sonarr, and Radarr run on a Pi 4 or Pi 5. Tdarr’s encode workload usually needs more horsepower than a Pi can offer.
Are these legal? The apps themselves are legal open-source tools. What you point them at is your responsibility — most users index legally-acquired content or releases they have rights to.
Can I replace Plex Pass with these? Tautulli covers analytics. Sonarr and Radarr cover automation. Plexamp is Plex Pass-only — for that one you either pay or move music to a different player.
