The idea wall for
the tablet in your drawer.

A shared sticky-note wall that syncs across your devices in about a second. No accounts, no app store, and no requirement that your hardware was made this decade.

Windows, macOS, Linux. Your notes never leave your network.

The outlined box is someone else, showing where they are on the wall right now.

Its screen is fine. Its battery is fine.

What died was software support — and then every whiteboard tool decided it needed a GPU. Miro, Excalidraw and tldraw all render to a canvas, which is precisely what a 2012 tablet cannot do. Attic is built the other way round.

No canvas, no WebGL

Notes are plain HTML elements and zoom is a CSS transform. You get the infinite-canvas feel without the hardware bill.

No WebSocket

Sync is ordinary HTTP polling. It survives flaky wifi, sleeping tablets and captive portals far better — and works in browsers older than WebSocket itself.

Built for e-paper

An e-ink mode for Boox, Kindle and reMarkable: maximum contrast, borders instead of fills, colour re-encoded as texture, and slower polling so the panel stops refreshing under you.

A mode with no JavaScript

For hardware older than the idea of a web app, the whole wall renders server-side as plain HTML with a form. It is not pretty. It works.

A wall, or a board

Rooms live at their own address — /kitchen, /sprint — and are created by being opened. Switch a room between layouts whenever the work changes shape; nothing is lost either way.

Free wall

Notes anywhere. Drag, resize, connect them with lines. Pan and zoom the board.

Columns

A real kanban: a card belongs to a column, and dropping it elsewhere moves it. To do / Doing / Done, retro, or a column per weekday.

Display mode

For a wall-mounted tablet: chrome hidden, dragging off so nobody rearranges the board by brushing past it.

Read-only links

Add /view to any room to share it with nothing to press — auto-fitted, with a greyscale switch for projectors.

That last row is not a missing feature. A pre-2008 device cannot negotiate modern TLS and has no current certificate authorities in its trust store, so it can never reach an HTTPS site. On your own network, over plain HTTP, it works fine. We would rather say so than let you find out.

Three minutes

No account to create, nothing to configure.

Run it

Download the app and open it, or run node server.js on a Pi or NAS. No dependencies, no build step.

Point a camera

The app shows a QR for your machine's address. Scan it with the old tablet — there is nothing to install on it.

Pin a note

It appears on every other device in about a second. Prop the tablet on a shelf and leave it there.

Run it yourself

Self-hosting is the product, it is free, and it stays free. Hosting is the part that costs money to run, so hosting is the part that will cost money.

On-premise means no login. Attic has no accounts and no password screen — the security boundary is your network. That is what lets a wall-mounted tablet come up showing the wall instead of a sign-in form. Keep it on your LAN or behind a VPN; do not port-forward it to the open internet. Multi-tenant hosting with real accounts is the emailed option above.

Attic is free and there is nothing to upgrade to. If it saved you buying a tablet, buy us a coffee — entirely optional, and it changes nothing about what you get.
