Kanban board.

A board of columns, usually To do, In progress and Done, with a card for each piece of work. Moving a card to the right shows its progress, and a glance at the columns shows what is waiting, what is moving and what is finished.

In this browser's localStorage, on this device, a moment after each change and again when you leave the page. Another browser opens on the sample board; download yours as JSON to move it or keep a copy.

A title, a short tag such as Design or Bug, and a note. Press a card's title to edit all three or delete the card; the tag shows in small capitals and the note's first two lines show under the title.

Up to eight. Add column puts a new one at the end, ready to name; press a column's name to rename it, and its bin icon deletes it with its cards. The last column can't be deleted.

Tab to the card's grip handle and press an arrow key: up and down move it within its column, left and right to the next column at the same place. The focus stays on the card, and the status line says where it went.

Yes. With a mouse, drag a card from anywhere on it; with a finger, drag it by its grip handle, so the rest of the card still scrolls the page. A line shows where the card will land.

Yes. Undo, or Ctrl+Z (Cmd+Z on a Mac) while you're not typing in a field, steps back through the last 30 changes: moves, edits, deleted cards and columns, and Clear cards.

The copy icon takes the board as Markdown, a heading per column and a bullet per card with its tag and note. The download icon saves it as JSON, which Open a board reads back here.

No. The board runs in your browser, makes no request with your cards and needs no account. Nobody else can see it, which also means there is no sharing or sync between devices.

No. The "Kanban board" tool is free and opens without a sign-in, an account or an install.

A sample board: To do, In progress and Done, with seven cards from a small team's week. Clear cards empties it and keeps the columns, and Undo brings the cards back.

Up to 8 columns, with no set limit on cards. A card's title holds up to 200 characters, its tag 24 and its note 2,000.

One localStorage entry on this device, holding the columns and their cards. The undo steps live only while the page is open, and nothing is sent to a server.

It opens its own JSON: an object with a list of columns, each with a title and its cards, each card with a title and, if you like, a tag and a note. Another app's export needs reshaping to that first.
