Sack Stack
Version 1.0.0
Sack Stack helps you organize and balance the weight of your bags before any trip. Whether you are hiking, camping, or traveling with checked luggage, you can plan exactly what goes where and make sure no single bag — or carrier — ends up overloaded.
Multiple bags & carriers
Create any number of bags and assign them to people, pets, vehicles, or anything that carries a load.
Weight tracking
Every item and bag has a weight. See running totals, warnings when bags get heavy, and balance across carriers.
Packing checklist
Mark items as packed and review your progress with a dedicated checklist view.
Import & export
Back up your trips as JSON files and restore them anywhere. Import item lists directly into an unpacked tray.
Share trips
Generate a link that encodes your trip right in the URL. Recipients open it and get the full plan instantly.
Privacy first
No accounts, no login, no tracking. All data stays in your browser and is never sent to any server.
This is a fully client-side web app. It is designed to work offline as a PWA and can be installed on your phone or desktop. If you ever want to start fresh, visit the Privacy & data page to clear everything.
