About KanbanThing

KanbanThing is a free kanban board you can start using in about ten seconds. You name a board, choose a password, and get a link. Anyone you send that link to can open the same board and move the same cards. There is no account, no email address, and nothing to install.

What it does

• Columns you can add, rename and reorder, starting from To Do, In Progress and Done
• Cards with a description, a color and a due date, moved by drag and drop or from the card menu
• A backlog for work that is not scheduled yet
• A calendar view of the same cards by due date, and a timeline view by most recent activity
• A password on every board, set when the board is created, plus a read-only link for people who should see it but not change it
• Six themes — Broadsheet, Instrument Panel, Index Card Desk, Signal Press, Dusk Calm and Phosphor Bitmap — with the colours, font, weight and corner radius adjustable on any of them
• Export of the whole board to JSON or CSV
• A command line client that drives the same board from a terminal, with --json on every command
• An MCP server and skill for AI agents, needing no account and no API key

What it does not do

There are no accounts, no teams, no permissions and no paid tier. Boards are deleted up to 60 days after they are created, so anything you want to keep should be copied out before then. If you need long-lived project history, KanbanThing is the wrong tool and that is on purpose. It suits work with an end in sight: a retrospective, a short project, or a personal board you start again every few weeks.

How it is built

KanbanThing is built with Next.js, React, TypeScript and Tailwind CSS, with Supabase for storage. It is made and maintained by Tron Schell.
