PuzzlePKM: Local-first PKM tool for MacOS with CLI and SQLite

A fresh approach to personal knowledge management (PKM) is gaining attention for MacOS users who value speed, simplicity, and data ownership. PuzzlePKM, an open-source tool, introduces a local-first architecture with strong command-line support, offering an alternative to cloud-dependent knowledge platforms.

Designed for speed and control

PuzzlePKM differentiates itself by prioritizing local storage and a command-line interface (CLI) over cloud syncing. Unlike many PKM apps that rely on external servers, this tool keeps all your notes and references in a local SQLite database. The design ensures faster access and stronger privacy, as your data never leaves your device unless you explicitly choose to sync it.

The tool supports multiple object types, including daily-note, topic-note, habit, project, ref-material, scripture, and tag. This structure helps users organize content based on context rather than forcing a one-size-fits-all format. Rich text editing is handled natively, and the system automatically creates bidirectional links between related notes, streamlining navigation and discovery.

Dual interface for flexibility

PuzzlePKM offers two ways to interact with your knowledge base: a desktop interface and a CLI. The desktop app, built with React, TypeScript, and Vite, provides a visual way to browse and edit notes. Meanwhile, the CLI—written in Node.js 22+—enables power users to manage content from the terminal, ideal for those who prefer keyboard-driven workflows.

The CLI tool is launched via cli.mjs, while the desktop interface runs under a Tauri wrapper. Both modes connect to the same local database, ensuring consistency whether you’re typing commands or clicking through a graphical interface. This dual approach caters to different user preferences without compromising on performance or features.

Built for privacy and portability

Security and data control are central to PuzzlePKM’s design. Since all notes reside in a local SQLite database, users have full ownership of their information. The tool also supports syncing to a local folder, allowing for manual backups or integration with version control systems like Git. This flexibility is particularly useful for researchers, writers, or anyone handling sensitive data.

The system’s stack includes Node.js 22+, SQLite for persistence, and Tauri for the desktop shell. The lightweight architecture minimizes overhead, making it suitable for both casual and intensive use. For those concerned about long-term access, the local-first approach ensures that your knowledge base remains accessible even without an internet connection.

Getting started with PuzzlePKM

To try PuzzlePKM, users need Node.js 22 or later installed. The installation process is straightforward: download the macOS DMG from the releases page, mount the image, and drag the app to your Applications folder. The CLI can be run directly from the terminal once the package is installed.

The tool is currently stable and ready for everyday PKM tasks. Whether you’re tracking projects, organizing research, or managing daily notes, PuzzlePKM offers a streamlined alternative to mainstream PKM solutions. As the project evolves, users can expect continuous improvements and community-driven enhancements.

For developers interested in contributing or customizing the tool, the open-source repository provides full access to the codebase. With its focus on local-first principles and CLI efficiency, PuzzlePKM stands out as a compelling option for MacOS users seeking control over their digital knowledge.
