Signboard is a local-first kanban app that stores lists as folders and cards as Markdown files.
If you are using the desktop app, begin with Using Signboard.
If you want to automate Signboard, script it, or drive it from an agent without MCP, go to Signboard CLI.
If you want structured tool access from an agent, see MCP Server.
- Creating and organizing boards, lists, and cards
- Due dates, task lists, labels, and board views
- Archiving and restoring cards and lists
- Board settings including colors, labels, tooltips, notifications, and imports
- Keyboard shortcuts
- CLI setup, command reference, filters, JSON output, archive workflows, settings, and imports
Signboard is intentionally simple on disk:
- A board is a folder.
- Each list is a subfolder inside the board's folder.
- Each card is a Markdown file inside a list folder.
- Board settings are stored in
board-settings.md. - Archived cards and lists live in
XXX-Archive.
That makes boards easy to inspect, back up, sync, and automate with standard filesystem tools.
