# Laneboard

> Kanban boards in your browser: lists, cards, checklists, due dates and flow charts. Laneboard keeps your work on kanban boards: lists of cards you drag from “to do” to “done”, by mouse, finger or keyboard. Cards hold Markdown notes, labels, people, due dates, checklists, comments and links; filters, a table and a calendar show the same cards another way. Everything is stored in your browser, with Trello import, JSON and CSV export, read-only share links and statistics that the API and MCP tools compute the same way.

Laneboard (Kanban boards) is an app of usefulweb.app (https://usefulweb.app/): a full program that runs in the browser. Its engine is deterministic and the same functions are exposed as tools, so an agent can compute exactly what the app shows.

## Limits
- No live collaboration or accounts: boards live in one browser; share them as read-only links or project files.
- Attachments are links only; files are not uploaded or stored.
- No swimlanes, custom fields or recurring cards.
- Trello imports skip custom fields, power-ups, stickers, start dates and image covers, and Trello exports hold only the latest 1000 actions.
- Very long share links (big boards) may not fit in every chat app; use a project file instead.
