Why build Signboard?
I built Signboard to get more done and not be dependent on the cloud.
I was inspired by the “file over app” philosophy and my love of visual planning tools.
Each card in Signboard is a Markdown file in a folder on your computer. As you move cards from one list to another the Markdown file moves between folders.
In a world of agents, CLIs, and MCP servers you can directly interact with all of your Signboard data seamlessly on any desktop platform.
Use the app, your text editor, the terminal, Claude, Codex, Gemini, OpenCode or any agent without moving your work into a private database.
Kanban, Table, and Planner
Use Kanban for drag-and-drop flow, Table for dense scanning and age sorting, and Planner for Calendar, This Week, Day, and Agenda views across your open boards.
Features
A little something for everyone.
Due Dates
Cards and individual Markdown tasks can have due dates.
Task Checklists
Use Markdown checkboxes with progress counters and task-level due dates.
Kanban & Table
Drag cards through Kanban or scan, move, and sort them in Table.
Planner
Calendar, This Week, Day, and Agenda views across open boards.
Quick Add

Keyboard & Accessibility
Keyboard navigation, status announcements, reduced motion, and forced colors.

Signboard 1.5 has more features than you’ll ever use
There is no white-walled room, pre-recorded, distillation of the essence of chamfered edges here… or talk about liquid anything. This post is about how Signboard is quickly becoming so feature-rich you likely won’t use them all. Signboard 1.5 just shipped and the landing page has been updated. This release brings much tighter Obsidian integration (including…

I’m trying to record a demo video of all of Signboard’s features, including those that will ship in version 1.5 (coming soon), and I’m just failing miserably. I’ll do it another day. So many great features in this app.

Version 1.3.0 changes up the typeface in the card editor, and adds checkboxes next to task list items making them easier to mark as complete while retaining full Markdown syntax.…

What do you do at 5am on a Friday? I release new versions of Signboard. Signboard 1.2.0 includes the following improvements: Until this release, Signboard’s archive was a black box.
