Is the cnvs.app kanban board really free?

Yes. Every cnvs.app board is free with no signup. Switch a board to to-do mode while it's empty and you get unlimited columns and cards with real-time multi-user sync at no cost.

Do I need an account to use the to-do board?

No. There are no accounts. Open a board, switch it to to-do mode, and share the link. Anyone with the URL can add and reorder cards live.

Can AI manage tasks on the board?

Yes. cnvs.app exposes a public MCP endpoint at https://cnvs.app/mcp with task tools (set_board_mode, create_task, move_task, list_tasks) and a 1:1 REST mirror, so Claude, GPT or any agent can create, move and complete cards alongside humans.

What fields does each card have?

Each card has a name, optional description, priority, due date, assignee and a done state. Cards live in columns, optionally grouped into named lanes (rows), and can be dragged to reorder or move between columns.

A free online kanban / to-do board with real-time sync and no signup

Every cnvs.app board can be a kanban to-do board instead of an infinite canvas. Switch the mode while the board is empty and you get columns, optional lanes, and cards carrying priority, due date, assignee and a done state — all syncing live to everyone with the link. No account, no install, and a public MCP endpoint so AI agents can manage tasks alongside you.

How a cnvs.app to-do board works

A board is either draw (the infinite canvas) or todo (a kanban task board). You pick the mode with a single button while the board is still empty — once a board has content the mode is fixed, so a drawing never silently turns into a task list. In to-do mode the board becomes:

Columns — your workflow stages (e.g. Backlog → Doing → Done). Columns share one width so the board stays tidy.
Lanes — optional horizontal rows that group cards within columns (e.g. by team or epic). Lanes can be named or left blank.
Cards — each task carries a name, an optional description, a priority, a due date, an assignee and a done state.
Drag to reorder — move cards within a column or across columns and lanes. Full touch support, so it works on a phone or tablet.

What each card holds

Field	What it's for
Name	The task title — the one required field.
Description	Optional longer detail / notes on the card.
Priority	Flag how urgent a task is, set inline while adding.
Due date	When it's due — set inline while adding.
Assignee	Who owns the task — set inline while adding.
Done	Mark a card complete without deleting it.

You can paste a plain list of lines and turn each line into its own task, and delete a hovered card straight from the keyboard (Del / Backspace).

Real-time, multi-user, no signup

Cards, columns and lanes sync over the same real-time WebSocket layer as the drawing canvas. Open the board on two devices, add a card on one, and it appears on the other within a moment — no refresh. There are no accounts and no tracking: the board ID in the URL is the only key. Share the link and everyone can edit. More on real-time collaboration →

Offline & installable

cnvs.app is an installable PWA. Every board you've opened is cached for offline read-only access, so you can review your task board on a flaky connection — edits sync back when you're online again. More on offline / PWA →

AI collaborators via MCP

The same public Model Context Protocol endpoint at https://cnvs.app/mcp that powers AI on the drawing canvas also manages tasks. An MCP-aware AI like Claude can create, move, complete and list cards on a shared to-do board:

set_board_mode   — switch an empty board to todo mode
create_task      — add a card (name, description, priority, due, assignee)
move_task        — reorder / move a card between columns and lanes
list_tasks       — read the current board as structured JSON

Every tool has a 1:1 REST mirror — POST /api/boards/<id>/mode, POST/DELETE /api/boards/<id>/columns, POST/DELETE /api/boards/<id>/tasks (+ /tasks/<id>/move) — and the subscribable resource cnvs://board/<id>/tasks.json so an agent gets a push when the board changes. See the developer docs →

Export

A to-do board exports to PDF straight from the browser — handy for a printed standup snapshot or an attachment — and the structured board state is available as JSON over the API for any downstream tooling.

FAQ

Is the kanban board free?

Yes — every board is free with no signup, including unlimited columns and cards with real-time multi-user sync.

Can I switch an existing drawing into a to-do board?

Only while the board is empty. The mode (draw vs todo) is fixed once a board has content, so a drawing never turns into a task list by accident. Open a fresh board to start a to-do board.

Does it work on mobile?

Yes. Dragging cards has full touch support, so reordering works on phones and tablets, and the board is installable as a PWA.

Can an AI run my board?

Yes — via the public MCP endpoint and its REST mirror, an agent can create, move, complete and list cards alongside human collaborators. More on AI via MCP →
