LIVE DEMO · NO LOGIN · NOTHING TO INSTALL

This is the real thing, running right now.

Not screenshots, not a video. Behind this page is an actual HEARTH server with a media library, a five-room house of devices, the cabling between them, and scenes that compile and run. Open it and click anything.

It is read-only, so you cannot break it — and neither could anyone who wandered in before you. Everything else behaves exactly as it does in a house.

01 · What to try

Four doors into one server.

HEARTH has two halves on purpose. The media app stays simple enough to hand to whoever is on the couch. The control system is the installer's workstation. One box serves both.

01 · MEDIA The media app A poster wall of the library. Pick a title and press Watch here — the film really streams, out of this server, into your browser. This is the screen a household actually lives in. OPEN → 02 · CONTROL Device manager & patchbay Five rooms: TVs, an AV receiver, a 4×4 HDMI matrix, a projector, an audio matrix, switched outlets. Walk the rooms, open a device, then look at the signal-routing patchbay — every cable in the house drawn as a line you can follow. OPEN → 03 · REMOTE The phone remote What a guest gets handed. Pick the room you are standing in, then power, source, transport, volume — and All off for the whole house. On a phone you add it to the home screen; that is the entire install. OPEN → 04 · KID MODE Kid mode The big-button surface for a child. The parental filter behind it is a server-side rule — a blocked title is never sent to the device at all, so there is nothing on the tablet to get around. OPEN →

Worth doing while you are in there

Run a scene — Movie Night, Theater Mode, Game Time. Watch it compile into ordered steps instead of a promise.
Follow a signal — pick a source and a screen and let it plan the path across the receiver or the matrix.
Open the console — the live backend log, streaming what the server does as you do it.
Read the DIY build — parts list, flashing steps, and fab-ready schematics for building the controller yourself.

02 · How this demo works

Straight about what you are looking at.

This is a full HEARTH install on a server I run, seeded with a five-room show house and a small library of open-licensed films. It is a separate instance from the one in my own living room — nothing you do here reaches my house, and nothing here is anyone's private library.

Writes are refused at the front door, so the house you see is the house the next visitor sees. Scenes still compile and still run; they simply have no hardware on the other end, and they say so plainly rather than pretending.

The one thing a hosted demo cannot show you is the whole point of the product: on a real install the server sits on your network, next to the gear, and reaches it directly. That is why this is a box you own instead of a service you rent.

Read-only: every write is refused at the edge
Isolated: its own instance, own data, own library
Library: open-licensed films — Blender Foundation, CC-BY
Hardware: none attached — scenes compile and report as planned
Accounts: none needed — profiles are shown, not stored
Your house: runs on your own network, with none of this in between

Your house runs on a box you own.
