About this tool
A Kanban board is a task-management tool that turns work into cards and lines them up in columns such as To Do, In Progress, and Done, making your workflow visible. Moving a card from one column to the next shows progress at a glance, so you can sense what is stuck and where capacity is free. It works for everything from a personal to-do list to tracking a team.
You create columns, give them titles, and add cards inside them. Cards move to a neighboring column by drag and drop or by button, and cards or columns you no longer need can be deleted. Your changes are saved automatically to your browser localStorage, so you can close it and continue next time. Nothing you enter is sent to a server.
The strength of Kanban is that it makes work in progress visually obvious. When cards pile up in the In Progress column, that is a sign you are spreading yourself too thin, and it becomes easier to decide to finish what you have before starting something new. A good pairing is to list every task first, sort priority with an Eisenhower matrix, and then place cards on the board.
You can export a board as JSON to load it back later and keep editing, or to move it to another device. Because it runs without a network connection, it is quick to jot things down the moment they occur to you.
How to use
- Name your columns (e.g. To Do / Doing / Done) and add cards to each.
- Drag and drop cards between columns to track progress.
- Use Add column to add more. Saved automatically. Use Export/Import JSON to save or share.
FAQ
Is the data stored on a server?
No. The board is stored in your browser localStorage and is not sent to any server, so you can safely use private task names.
Can I share it with another device or a team?
There is no real-time sharing, but you can export a JSON file and let someone else load it to share the contents. For work that needs constant sync, a dedicated team tool is a better fit.
How do I move a card?
Drag and drop a card to another column. In environments where dragging is awkward, you can also use the card buttons to move it to a neighboring column.
Can I add as many columns as I want?
Yes. You can add columns and title them freely. You are not limited to the three To Do / In Progress / Done columns; add things like In Review or On Hold to match your own workflow.
Does closing the page erase it?
No. It is saved automatically, so reopening the same browser restores it. Note that it is not retained after clearing browser data or in a private window.
Is there a work-in-progress limit feature?
There is no automatic enforced limit, but you can judge by eye whether the In Progress column has too many cards. When it fills up, holding off on new work and finishing first keeps the flow healthy.
