Built for the way you actually watch.
Every part of Quven was tested on real libraries and real hardware: direct play that leaves the file untouched, a catalogue that matches your files on its own, and clients that feel finished on every screen.
Built for the files you actually have
Quven plays your media at full fidelity and only transcodes when it truly has to. The hard parts, HD audio, HDR and styled subtitles, are the point of it.
Direct play, untouched
When a client can demux the source, Quven streams the original file as it is: no transcode, no quality loss and no extra load on the server.
Hardware transcoding
When a device can't decode natively, the server transcodes on the fly with auto-detected acceleration: NVENC, Quick Sync, CUDA, VideoToolbox.
HDR tone-mapping
HDR10 and Dolby Vision tone-mapped to SDR with a Hable curve, so highlights survive on screens that can't do HDR themselves.
HD audio, untouched
The server hands DTS-HD, TrueHD and Atmos tracks to the native players untouched, with no browser-style re-encode of your lossless audio. What a receiver finally does with the track is up to your player and your hardware.
Subtitles done right
Styled ASS/SSA, PGS and VobSub bitmap burn-in, plus sidecar files stored next to your media. Choose track and size at play time.
Many files, one title
A 4K rip and a 1080p remux of the same film live under one entry; Alternate editions names what differs between them and plays the one you choose.
Subtitles for the files that never had any
Subtitles are a first-class part of playback here: Quven plays the ones you have, writes one from the dialogue when there are none, and lets you correct the result.
Generated from the audio, locally (Pro)
No subtitle track and no sidecar? The server transcribes the dialogue on your own machine and saves it as an ordinary, reusable track. The audio never leaves your hardware, and once the track exists every plan plays it.
Accelerated by your GPU
Recognition runs on Metal on an Apple silicon Mac and Vulkan on Windows and Linux, falling back to an optimized CPU build, and it always leaves a processor to the rest of the system.
Image subtitles become text
DVD, VobSub and PGS streams are recognized into a text track you can search, restyle and translate, instead of a picture burned into the video.
Correct a track (Max)
The cue editor fixes wrong words, drifting timings and per-cue colour, then saves the result as its own file. The original track is never touched.
Translate any of them (Max)
On-demand AI translation starts from an embedded track, a sidecar file, a recognized image track or the transcript of the audio. Only the finished text is sent. Your audio never leaves.
Your records on the same shelf
Music is the fourth kind of library, free on every plan, and it arrived in 1.2.0. Point Quven at your album folders and the covers land beside the films.
Albums read out of your files
RoadmapTags come first and folder names fill in what a file left out, so Quven works out which artist and which pressing every recording belongs to.
Covers and lyrics
RoadmapA cover can come from the file itself or from the image sitting next to it, and lyrics from an embedded tag or an .lrc beside the track.
A queue that follows you
RoadmapDesktop and the hosted web client both give you a wall of covers, an album page and a queue that stays with you as you browse the rest of the library.
A catalogue that understands itself
Point Quven at your folders and it builds a real catalogue: matched, deduplicated, and rich with the artwork and ratings that make a library feel alive.
Automatic matching
Metadata is matched against four catalogues (TMDb, TVDB, OMDb and AniDB), and the matcher copes with release-scene naming in five languages, a year that's off by one, and leet substitutions.
Manual match when it counts
When the matcher isn't confident, it asks: a manual-match dialog with a tab per catalogue, and a 'needs review' inbox you can confirm in batches.
Movies, shows, documentaries & performances
Separate libraries with the right shape for each: feature films, season/episode trees, and documentaries or performances detected file by file as a whole recording or one night of a run. A recording no catalogue knows, you describe yourself.
Background scanning
Scans run in the background with live progress, and you're the one who starts them. Nothing kicks off behind your back, and a cancelled scan can be resumed.
Cinematic detail pages
Backdrops, score arcs, multi-source rating pills (TMDb, IMDb, Rotten Tomatoes, Metacritic), cast strips and related rails.
Optional AI tie-breaking
An optional AI step breaks matching ties, repairs zero-result queries and names a file nothing else could identify. Use managed AI matching on a paid plan, bring your own key, or leave it off entirely.
Premium on every screen
Native is where the engineering goes. Desktop stays full-fidelity, Android and Apple now have platform-native clients, and the web client remains a first-class fallback.
Native desktop app
A real native client on Avalonia: dark/light themes, command palette, keyboard shortcuts, resume, audio/subtitle/aspect pickers and a stats overlay.
Drive it all with a controller (Pro)
An Xbox-compatible pad drives the Windows desktop from the sofa, and you assign what every button does on a drawn pad in settings. macOS is coming.
Premium web client
A cinematic browser client with a serious HLS player. It's the fallback for when there's no native app at hand, away from home or on a guest device.
Exclusive iPhone & iPad
A SwiftUI client built for Apple devices: dynamic iPad layouts, pointer-aware controls, keyboard shortcuts, widgets, PiP, AirPlay handoff and native sheets.
Android phone & tablet
A Kotlin/Compose client with adaptive touch layouts, Material 3 chrome and libmpv-backed playback for broad codec, subtitle and HDR coverage.
Android TV
The same Google Play app extends to a remote-first ten-foot surface with focus-safe controls and TV shell navigation. It is verified on Fire TV hardware too, ahead of its Amazon Appstore listing.
Finds your server itself
After sign-in, the client discovers linked servers over mDNS on the LAN or lists the remote servers already attached to your account.
Reach it your way
Stay in your living room or reach your library from the other side of the world. Local is always full-speed and free; the managed relay is there when you don't want to touch a router.
Self-hosted remote (free)
Reach your server from outside your LAN with your own port-forward, reverse proxy or Tailscale. Your bandwidth, your rules, always free.
Managed relay (Pro)
Or flip on the managed relay and reach your server through NAT and CGNAT with zero configuration. You pay only for the convenience.
Profiles & watch state
Unlimited household profiles on every tier, with optional PINs and cloud-synced watchlists, ratings, reviews and resume points.
Account sign-in
Sign in with your email and password; verified email and self-service password reset keep recovery simple, and the same identity works across every device and server.
Read it from your own dashboard
Issue a named key and point Homepage, Grafana or a script at your server. The key is read-only by construction and can never change anything or mint another; it reports the libraries, the counts and what is playing, and never your folder paths or who is watching.
Yours, not ours
Your media stays on your hardware. Quven Account handles identity, linked servers and profile data so the household can move between installs.
One cloud identity
Every app starts with Quven Account sign-in, then lets you pick a local server, a remote server, or finish a new server setup.
Runs on your hardware
Your media files never leave your machine for local playback. Profile data syncs through Quven so reinstalling a server doesn't erase it.
No retroactive paywalls
Nine things are free for good and the plans page lists every one, so you can hold us to it. Anything outside that list can change tier, and when it does the changelog and the plans page will say so before you find out from a button.
