Nullboard

Nullboard is a minimalist kanban-style task manager implemented as a single-page HTML application. It keeps data in the browser (localStorage), provides editable in-place notes and supports multiple boards with quick switching.

Key Features

• Single-file single-page web app implemented in plain HTML/JavaScript/CSS for a very small footprint
• Browser-local storage of boards and notes (localStorage) with manual export/import in JSON format
• Multiple boards with near-instant switching and compact, readable layout
• In-place editing, keyboard shortcuts and drag-and-drop note/list reordering
• Undo/redo history (defaults to 50 revisions per board) for quick recovery of recent changes
• Note collapsing for compact views and configurable font/zoom/theme options (including inverted/dark theme)
• Optional automatic local backup via companion agent utilities (platform-specific agents exist)

Use Cases

• Personal task and project organization where data should remain local and private
• Quick, ephemeral planning boards for meetings, sprints or brainstorming sessions without server setup
• Portable offline-toolkits for users who prefer a compact, keyboard-first kanban interface

Limitations and Considerations

• Primarily designed for desktop (keyboard + mouse); touch/tap and mobile support are essentially untested
• Uses browser localStorage: boards can be lost if browser data/cache is cleared or profiles are removed
• No built-in multi-user collaboration or server-side sync; sharing requires export/import or external syncing tools
• Project is labeled beta and uses a license that includes a Commons Clause restriction; commercial resale is restricted

Nullboard is a lightweight option for users who want a distraction-free, locally-stored kanban board with minimal dependencies. It is best suited to single-user or local workflows where simplicity and privacy are priorities.
