How many bags of frozen peas do you own right now? If you can't answer that, you're paying twice for the same food.

A chest freezer is a black hole. Stuff goes to the bottom, gets buried, and freezer-burns into oblivion while you buy fresh at the store. A self-hosted freezer inventory fixes this. No app store account. No company scanning your grocery habits to sell you ads for pizza rolls.

Why not just use a notes app?

A notes app doesn't count. Freezer inventory is about quantities that go up and down. You pull out chicken, the count drops. You buy a fresh pack, it goes up. A plain note becomes a scribbled mess in a week. You need something you can update in five seconds from your phone.

The tool: Grocy

Grocy is a free, self-hosted "household ERP." That sounds intense, but you only need one piece of it: stock tracking. Ignore the rest until you want it.

Run it with Docker in one command:

docker run -d \
  --name grocy \
  -p 9283:80 \
  -v grocy_data:/config \
  linuxserver/grocy

Open http://your-server-ip:9283 and you're in. Everything lives on your machine. Nothing phones home.

Set it up in 20 minutes

  1. Create a location called Freezer.
  2. Add your products: "Frozen peas," "Ground beef," "Chicken thighs." Just names, no fuss.
  3. Do one honest count. Open the freezer, dig to the bottom, log every item with its quantity.

That first count is the boring part. After that, it's a 5-second tap.

The habit that makes it stick

Two rules:

  • Take something out? Tap "consume."
  • Put something in? Tap "purchase."

Stand at the freezer, phone in hand. Do it right then, not later. "Later" never comes.

Before you shop, pull up the list. You'll be shocked how often you were about to buy something you already have three of.

Bonus: catch food before it dies

Grocy tracks expiry dates too. Add a "best before" when you log an item and it warns you when something's aging. That salmon fillet from four months ago? It'll flag it before you find it fossilized.

Why self-host this at all

Commercial pantry apps want your email, your shopping patterns, and often a subscription. Your food inventory reveals your diet, your budget, your household size. That's worth keeping to yourself. A self-hosted list answers to nobody.

Your one action today: Install Grocy, create a "Freezer" location, and log just five items. Small start, real habit. Your next grocery bill will thank you.
