Rexarr is a remux-first transcoding companion for Usenet and BitTorrent users of the \*arr stack. It sits next to
Radarr, Sonarr and Lidarr, finds Blu-ray remux and full-disc releases for the titles you choose, and re-encodes what
they import with FFmpeg – or fre:ac for music – using profiles you control. It can also rip discs with MakeMKV,
split album images, and find media on your disks that none of the \*arr apps manage.

## How it compares

Automatic Ripping Machine, Tdarr, Unmanic, or MakeMKV and HandBrake by hand — what each is better at, and what
Rexarr does not do: [How it compares](https://moonlightlaboratory.github.io/rexarr/comparison/). What is missing
and what comes next — stability before features while Rexarr is in beta — is on the
[roadmap](https://moonlightlaboratory.github.io/rexarr/roadmap/).

## Features

### Current Features

- Web UI in the \*arr style – Movies, Series, Music, Search, Activity, Discs, Profiles, Settings and System
- Smart search across your library, TMDB / TVDB and AniDB, typo tolerant, understands `S01E05`, `2160p`, `remux`, `dv` and ids
- Remux-first release search through Radarr, Sonarr, Lidarr and Prowlarr, ranked by source quality
- Full-disc (ISO / BDMV / VIDEO_TS) releases ripped with MakeMKV after download, then encoded and imported
- Encoding profiles for x264, x265, SVT-AV1, libaom, VP9 and hardware encoders (VideoToolbox, NVENC, QuickSync, VAAPI, AMF)
- Built-in presets for movies, TV and anime, with HDR10 passthrough, audio / subtitle selection and font attachments
- Estimated output size for every profile before you encode
- Release-style output names (`Remux-2160p` → `Bluray-1080p`) with clean track metadata
- Automatic transcoding of new imports, with live progress, preview frames and the full FFmpeg log
- Disc ripping from physical drives and virtual drives (ISO files and folders)
- Music with Lidarr: fre:ac profiles using open-source encoders (FLAC, WavPack, MP3, Opus, Vorbis), audio CD ripping with MusicBrainz, MQA detection
- Soulseek (slskd) album search, and automatic splitting of image + cue downloads Lidarr cannot import
- Local media: finds movies, series and albums outside the \*arr apps, with TMDb, MusicBrainz and Cover Art Archive metadata
- Queue pause / resume, stall watchdog, free-space checks and network share health checks
- Path mappings, authentication, reverse proxy URL base, HTTPS, backups and scheduled tasks
