Kanban board PRO: tasks and projects offline — one HTML file

Kanban board PRO: tasks and projects offline — one HTML file

BOARDS, COLUMNS AND CARDS WITH NO SUBSCRIPTION OR SIGN-UP — JUST OPEN THE FILE

A full kanban in a single HTML file: drag cards, enforce WIP limits, read the
analytics. Works fully offline; the data stays in your browser and is never
sent anywhere.

EXAMPLE FROM THE SCREEN (the real demo board that opens on first launch):
• 14 cards in 4 columns: Backlog 3 · To do 3 · In progress 3 (WIP limit) · Done 5
• Average card cycle — 25 days, board completion 36%
• 5 cards closed over 4 weeks, 1 overdue (highlighted in red)
• The Cumulative Flow chart is built from 29 days of real event log

WHAT´S INSIDE (everything works right away, nothing to configure):
• Unlimited boards and columns — "+ Board" and "+ Column" buttons
• Cards: priority (urgent/high/medium/low), labels, due date, description
and a checklist of subtasks
• Drag & drop with the mouse; on a phone, "← left" / "right →" buttons
inside each card
• WIP limits: the column count turns red when a limit is exceeded
• Search by text, filter by label, and "overdue only"
• Analytics: KPIs, day-by-day Cumulative Flow, weekly throughput,
WIP violations
• Export to CSV (Excel), JSON backup, backup import, print the board
• Dark and light themes
• Undo up to 40 steps (Ctrl+Z), hotkeys N and /

WHO IT´S FOR:
• A freelancer juggling several projects — one board per project
• A team of 1–3 people who don´t need a corporate monster
• Anyone tired of subscriptions: buy once, works forever
• Personal tasks and goals where you want to see the progress
