Kanban Board
A private kanban board in one HTML file on your machine: no account, no cloud, no server to talk to.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
The work is somewhere between started and finished, which is exactly where things get lost. The Kanban Board keeps each card honest — what it is, whether it's to do, in progress, or done, when it's due, and notes — three columns that tell you the truth at a glance.

Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in (Card, Column, Due and Notes) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of kanban board entries is a decade of your own handwriting, kept in a document you can back up like any other.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Who else sees this
Nobody. Your Card, Column, Due and Notes never leave the file on your own disk. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Productivity tools →
Questions people ask
How does a simple kanban board work?
Every task is a card with a column: To do, In progress, or Done, plus a due date and notes. Work moves left to right, and the In progress column tells you immediately when you've started too many things.
Is there a kanban tool that doesn't require an account or a team plan?
This one. It's a single HTML file that runs offline in your browser — no sign-up, no per-seat pricing, nothing leaves the page. You own the file the way you own a notebook.
Can I use kanban for personal tasks, not just software work?
Absolutely — kanban was born in factories, not standups. House renovations, wedding planning, job hunting: anything with too many moving pieces earns its three columns. The demo on this page is live if you want to move a card.
