Kanban Board Data Generator

Realistic board data for kanban prototypes

The Kanban Board Data Generator produces fake board JSON — columns holding cards with assignees, labels, priorities, due dates and point estimates. It is built for prototyping Trello-style and Jira-style project boards without hand-writing fixtures or wiring a backend first.

How it works

You set the number of columns and the number of cards per column. The generator takes column names from the standard kanban flow (Backlog, To Do, In Progress, Review, Done) and, for each, builds the requested number of cards. Each card draws its title by combining a verb and a noun phrase from curated pools, picks an assignee, selects one or two distinct labels, assigns a priority and a Fibonacci-style point estimate, and sets a due date within the next sixty days of a fixed base date. A seeded pseudo-random source keeps a given configuration stable between renders, and Regenerate advances the seed for fresh content.

The output is a single object with a columns array; each column carries an id, a name and an ordered cards array. This is the canonical shape board UIs use, so it maps cleanly onto column components that iterate cards. The live preview renders the board so you can sanity-check the data before copying it.

Tips and example

• Match your real board by setting the column count to the number of stages in your workflow — four columns gives Backlog through Review.
• Use a low card count per column while building drag-and-drop logic, then raise it to stress-test scrolling and virtualization.
• Each card carries a priority and points field, so you can immediately test sorting, filtering and swimlane grouping.
• Because due dates are real upcoming dates, you can wire up overdue highlighting and date-based sorting against the sample data.
