The packaging is gone
Most boxes are recycled within a week of setup. The commissioning QR code goes out with them, and nobody notices until the device needs re-pairing.
Matter Manager is a free, open-source catalogue for the commissioning QR codes of your Matter smart-home devices. The box gets recycled. The label ends up behind the washing machine, or inside the ceiling fitting. Matter Manager keeps the commissioning code, so re-pairing a device takes seconds instead of a factory reset and a support call.

The problem
Most boxes are recycled within a week of setup. The commissioning QR code goes out with them, and nobody notices until the device needs re-pairing.
A sensor behind a cupboard, a relay inside a wall box, a bulb in a sealed fitting. The label still exists. You simply cannot get a camera to it.
Without the code, the route back is a factory reset and often a support call — sometimes a replacement device, for hardware that never broke.
Why this works
Every Matter code is MT: followed by nineteen characters of Base38.
Those characters carry a version, a Vendor ID, a Product ID, the custom flow,
discovery capabilities, a 12-bit discriminator and a 27-bit setup passcode.
Two things follow. Keep twenty-two characters and the QR code can be regenerated forever, at any size, on any medium. And because the Vendor and Product IDs are in there, the manufacturer and product name fill themselves in rather than being typed.

That is the Matter specification's own test device. Nineteen characters, fully described.
How it works
First, create a free account by signing in with Google. That takes a minute and a connection, and it is the one part you cannot do offline — your catalogue lives in the account. Then, once per device:
Point the camera at the code on the device or its box. If a camera cannot reach it, type the code by hand instead.
Give it a name and a room. Manufacturer and product are filled in from the code itself. Add a photo, a serial number, an installation date if you want them.
Later — possibly years later — search by name, browse by room, or scroll the inventory for the house.
Get the QR code back on screen, or the numeric pairing code, or a printable PDF you can file with the house documents.
What it does
Camera capture, with manual entry for codes a camera cannot reach.
Name, room, device type, installation date, serial, photos and timestamped remarks.
Paths like Ground Floor/Kitchen, created inline while you add a device.
The original QR code on screen, plus the numeric manual pairing code.
Label sheets or a full inventory, grouped by room, all devices or a selection.
Once you are signed in, everything works with no connectivity. The basement is exactly where you need this.
One per house or apartment, shared read-only or read-write with other people.

What it is not
It does not commission devices. It does not control or monitor them. It never talks to your devices, your network or your Matter fabric.
It is a catalogue, and staying a catalogue is the point. It is why the whole thing works with no connectivity, why it needs no access to your home, and why there is nothing in it that can interfere with a system that already works.
Who it is for
One house, perhaps a holiday flat. Twenty or two hundred devices accumulated over years, from a dozen manufacturers. Share it with whoever else lives there, so re-pairing a bulb is not a job only one person in the household can do.
Commission a house, hand the catalogue to the owner on completion, and keep read access for support. The codes stay with the building rather than in a folder on one laptop.
Where things stand
Matter Manager is under active development and there is no 1.0 yet. Release 1.0 covers the local catalogue, scanning, PDF export, accounts and multi-device synchronisation. Development happens in the open, test-first, with the design decisions written down as architecture decision records.
If you would rather read the code than a landing page, that is entirely reasonable: github.com/beyonddemise/matter-manager, Apache-2.0 licensed.

Questions
No, and it never will. Matter Manager does not commission, control or monitor anything. It never contacts your devices, your network or your Matter fabric. It is a catalogue of codes and nothing more.
Yes. An account is how your catalogue exists, so creating one is the first step. It needs a connection, once — after that the catalogue, searching, QR regeneration and PDF export all work offline. The free tier asks for no payment details.
Everything except signing up and creating a new project, each of which needs one round trip. Adding devices, searching, generating QR codes and exporting PDFs all work with no connectivity — which matters, because the devices you need to look up are usually in the basement.
Setup passcodes are stored unencrypted, protected by database isolation and transport security. That is a deliberate, documented trade-off rather than an oversight, and it is written up in SECURITY.md so you can judge it yourself before trusting anything to it.

Your account
Matter Manager accounts are created with Sign in with Google. We ask Google for your account identifier, your email address and your name — nothing else. We cannot see your Gmail, Drive, contacts or anything else in your Google account, and we never learn your Google password.
The identifier is how signing in finds your catalogue. Your email address is how other people share a project with you. Your name is shown beside the remarks you write, and you can change it. None of it is used for advertising, sold, or used to train anything. The privacy notice has the full detail, including how to delete it.
