The rooms

Built for getting lost in what you've kept.

Six rooms, one quiet principle: everything stays in the building.

The living wall

A masonry video wall with smart sampling and auto-refresh — it fills whatever screen you've got and keeps it moving.

Persistent popouts

Pull any clip into its own window. Drag, resize, fullscreen — players stay pinned exactly where you left them, across sessions.

Precision loop-lock

Set an in and an out and Seraglio holds it frame-perfect — with cross-window sync so every player breathes together.

Pulse

Detect the BPM and sync your whole wall to it. The room breathes on the beat — set the tempo, let it ride.

Live cam overlay

Drop your camera into the frame and put yourself in the action — a quiet way to be part of the collection, not just watch it.

Local-first & private

Your files never leave your machine — no cloud, no account, no upload. Instant cooldown and a panic key whenever you need the room dark.

No cloud. No account. No upload.

Nothing leaves the room.

Seraglio runs entirely offline, on your hardware. It scales from a laptop to a wall of monitors and reflows to fit — built for collectors and creators who keep a large personal library and would rather no one else ever touched it.

100% offline No account, ever Instant cooldown + panic
One key, kept for good

Pay once. The whole palace.

Before you step in

Questions, quietly answered.

A local-first desktop app that turns a folder of video into a private viewing room: a self-arranging masonry wall, persistent popout players, precision loops, and a beat-synced pulse. It's content-agnostic — you point it at whatever library you keep, and it stays entirely on your machine.
Yes — 100% local. There's no account, no sign-in, and nothing is ever uploaded. Your files never leave your machine. Seraglio works with no internet connection at all, and includes an instant cooldown and a panic key to clear the room in a keystroke.
Seraglio runs natively on all three major desktop platforms — macOS, Windows, and Linux — and your license covers every one of them.
After checkout you'll receive a license key by email (it's also shown on the confirmation page). Enter it on first launch to activate. One key covers up to 3 machines, and Seraglio tolerates being offline — once activated, it keeps working without a connection.
Checkout and billing are handled by our merchant of record, Lemon Squeezy, and refunds follow their policy. If something isn't right, write to support@seraglio.app and we'll make it right. See our refund policy for details.
A desktop running macOS, Windows, or Linux — Seraglio ships as a lightweight native app for all three. The interface reflows from a single laptop screen to a wall of monitors, so there's no minimum display size. You bring the library; Seraglio handles the room.
