A Kanban board that speaks Markdown.

Drag-and-drop boards where every card is real Markdown — WYSIWYG editing, checklists, labels, comments, and file attachments, live-synced for everyone on the board.

A Markboard board with columns and cards, showing labels, due dates, and checklist progress

Everything a board needs, nothing it doesn't

Markdown-native cards

Every card description is real Markdown — a WYSIWYG editor by default, with a one-click toggle to the raw source when you want it.

Drag-and-drop boards

Columns and cards reorder instantly, within a column or across the whole board, and the order sticks on reload.

Labels, dates & checklists

Color labels, start/due dates with Overdue/Due Soon badges, and multi-checklist progress tracking — organize however your work actually works.

Comments & activity log

Discuss inline on any card, and see an audit trail of exactly who changed what, and when — per card and per board.

Real-time collaboration

A mutation by one teammate shows up live for everyone else watching the same board, within a couple seconds — no reload needed.

File attachments

Attach files up to 5 MB per card — Markdown and text files preview inline, everything else is a clean one-click download.

Bring your own AI agent

Markboard exposes an MCP server — connect Claude Code, Claude Desktop, or any MCP-compatible agent, and it can read and write your boards directly: create cards, check things off, search, comment — the same as a teammate would, attributed and live for everyone watching.
