Stacks

Stacks is a desktop application that organizes your projects, tasks, contacts, and notes in one place. It runs on Mac, Windows, and Linux, and it stores all your data locally on your computer by default. You can manage workflows using kanban boards, tables, lists, and a calendar, and the app includes features for task automation, deadline tracking, and generating reports. It is designed to work completely offline, though you can optionally set up your own private server for syncing across devices.

What makes Stacks stand out is its strong focus on privacy and data ownership. Your information never leaves your machine unless you decide to host a personal server. The tool is highly customizable, allowing you to tailor views and automate repetitive actions, like changing task properties when they move between columns. All data is stored in editable JSON files, so you are never locked into the platform.

This tool is ideal for individuals and teams who prioritize security and dislike subscription models. Students use it to manage assignments, freelancers organize client work, and small businesses keep project details confidential. It is especially useful for anyone working in disconnected environments or those who simply want a capable project manager that respects their privacy.
