A Kanban board made of Markdown
Boards live in your browser, so the UI is instant and works offline.
For anything you want to keep, run the sync server you host yourself.
↓ this is a demo, not a real board. "Open in browser" runs the whole thing: no signup, no install
Cards
4Cards are Markdown
GitHub-flavored Markdown:
bold, code, links, highlights.
Task lists carry a live count, up in the header (try clicking):
- Written in Markdown
- Slash menu for formatting
- Tick a box, watch the count
- Nothing left to do
I tried to make Markdown editing more bearable: slash commands, suggestions.
Attachments and tags
File attachments, inline images, support for dragging files into a card or pasting from the buffer:

Bracketed words become colored pills: design needs review
Deadlines
Set a due date and the chip shifts color as it nears.
Like this one, which has been overdue for a while.
Cards link to cards
Type [[ and pick a card. The reference (wikilink) carries its title and the column it's in: both read live, so a rename or a move updates every mention:

Where it lives
2Local-first
Boards live in the browser. Reads and writes hit your device, not the network, so it's fast, and it works offline.
Sync is opt-in
Point it at a server you run and boards replicate to every device in the background. Sync happens every couple of seconds, or on ⌘+S.
Run it
3Self-host in one line
Comes with an install script.
The script backs up your data, and bundles all you need to run the app. Re-run any time to pull newer images. It keeps your config. There's a self-hosting guide.
Runs where you do
In the browser, installed as a PWA, or a Tauri macOS app that reuses the same client and auto-updates.
No mobile app yet, but the PWA makes the mobile experience closer to native.
Agents can edit it too
The server exposes your boards over MCP, so Claude or other agents can read and edit them: create cards, tick task lists, move things.
