What Stacks is

Stacks is an all-in-one work and project management tool for projects, tasks, and communication. It lets teams view projects as boards, lists, tables, or calendars. Tasks can contain subtasks, assignees, due dates, attachments, and automation rules. Notepads organize notes, while contacts can be filtered, sorted, and grouped by company. Workspaces can sync through iCloud Drive, Dropbox, Google Drive, or another service. Stacks describes itself as offline-first, with data stored locally or on a self-hosted private server. The free Basic plan includes three projects, 10 contacts, three notepads, and one offline workspace, plus all project views and advanced filtering. Unlimited forever is listed at $49 a month as a one-time payment, limited to two devices. Stacks for Team costs $5 per user per month and adds real-time sync, access controls, time tracking, approvals, and advanced reporting.
