Kanri

A solo contractor tracking private client deadlines wants a visual workflow without handing sensitive task lists to remote cloud providers. Kanri provides a standalone desktop Kanban workspace that runs on Windows, macOS, and Linux with zero network dependency. Every board, column, and checklist item stays stored inside a local file on the user's hard drive.

Why Kanri instead of Trello

Trello requires creating an Atlassian account, routes card updates across remote servers, and caps free accounts at ten boards. For an individual who only needs to track personal tasks, that cloud architecture introduces data exposure risks and unnecessary complexity. Kanri replicates the familiar card-and-column layout of Trello directly on the desktop. Users can drag cards across custom stages, assign colored tags, append subtask checklists, and set due dates without sending a single byte over the local network. A built-in Trello importer also allows transferring existing boards from JSON exports without manual reconstruction.

The core distinction lies in ownership and operational scope. Trello targets distributed teams with real-time multi-user editing, power-up integrations, activity audit logs, and automated notifications. Kanri removes those collaborative layers in favor of local privacy. There is no cloud sync backend, tracking telemetry, or subscription paywall. The obvious trade-off is collaboration: Kanri cannot assign tasks to teammates or send email alerts. In return, users gain complete local sovereignty over their data, eliminating login friction and vendor lock-in.

What it does well

• Local JSON data storage: Stores all boards and cards directly in a local application file, guaranteeing complete data ownership and offline accessibility.
• Trello and GitHub Projects import: Accepts exported board files so switchers can transition existing workflows without retyping tasks.
• Card formatting with Markdown shortcuts: Allows writing descriptions with headings, lists, bold text, and clickable hyperlinks for structured notes.
• Board appearance personalization: Provides custom background images alongside built-in themes like Catppuccin, dark, and light modes.
• Subtask checklists with progress tracking: Breaks complex work into checklist items with visual completion counters on card covers.
• Granular JSON backups: Enables exporting individual boards or the entire database to an external drive or backup directory.
