What the code does

• Drag and drop cards between columns
• Checklists and due dates on cards
• Board state validated on import
• Hard limits on columns and cards

Tech stack

React 19, TypeScript, Vite, Tailwind CSS 4.

Install and customise

The How to install and How to use tabs list the steps. In short: unzip, npm ci, npm run dev, then copy the tool folder into your own app if you want to embed it.

Good to know

• A browser-only tool: there is no backend or database in the code.
• Data lives in one browser only; there is no sync or sharing.
