Cobblr

Cloud or self-hosted · source-available · 2026.8.1

Your inventory app, your way.

Point your phone at a barcode and the name, photo, and details appear. Then Cobblr keeps watch: what's running low, what's about to expire, where you put it. Groceries, yarn, Lego, the garage: one app, set up the way you actually live.

Every screenshot on this page is a real workspace, not a mock-up.

A Cobblr dashboard for a household: one grocery overdue, eight running low, seven expiring this week, and counts for the bookshelf, groceries, inventory, machines and assets.
A household, this morning. One thing overdue, eight running low, and the sourdough expires tomorrow.

Five setups, one click each.

It's the same app every time. Only the fields and the reminders change.

Use case · 🥬 Groceries

Your fridge, on your phone.

Scan the barcode at the door and it's in, photo and all. Cobblr knows what's in stock, dates it, flags it when it's low, and nags you before it expires, not after.

  • a shopping list that fills itself in
  • use-it-or-lose-it, sorted by what goes first
  • fridge, freezer, pantry, counter

Or get it as its own app: Cobblr for Groceries →

Cobblr's groceries table: real products with their photos, where each one is kept, when it expires, quantity steppers and a low badge on the ones at their reorder point.
The same groceries on a phone: one card per item with its photo, quantity, where it is kept and a low badge.

Use case · 🧱 Lego

Every set, matched to the real catalog.

Scan the box and the name, photo, year, and piece count come from the catalog, not your typing. Track what's built, what's boxed, and which bin the loose bricks went into.

  • sets, minifigs, loose parts
  • a member app for a club or a family
  • QR label on every bin

Watch the Lego club get its app 2:55

A Cobblr inventory table holding four Lego sets, each with its photo, and columns for set number, theme, year, piece count, build status and the bin it lives in.
The Lego Club member app in Cobblr: a dark themed screen with built and to-build counts, a Build Tracker toggle, a needs-pieces list, and Scan an item and New part buttons.

Use case · 📚 Bookshelf

Scan the back of the book.

Cover, author, and year arrive from the ISBN. Mark it read, give it a rating, and remember which room you left it in, or who you lent it to.

  • to read · reading · read · abandoned
  • a lending list for the ones that walk off
  • real covers, not grey squares
Cobblr's bookshelf: nine well-known books with their real covers, author, ISBN, year, reading status, rating and the room each one is in.
The bookshelf on a phone: one card per book with its cover, publisher, quantity and the room it is in.

Use case · 🏠 Home inventory

Everything you own, room by room.

Appliances with their serial numbers and receipts, rooms with what's in them, and the furnace filter that puts its next change on your calendar. Print a QR for the bin; scan it later to see what's inside.

  • rooms, closets, bins, the garage
  • service history and the next one due
  • one-click import from Homebox

Or get it as its own app: Cobblr for Home →

Cobblr's locations page for a household: Kitchen with Fridge, Freezer and Pantry under it, Living room, Garage, Basement, Home office and Hall closet.

Also running on Cobblr: a 30-machine print farm, a spice rack with a cabinet map, a garden that tells Home Assistant which zone to water, a garage that schedules its own next service.

Take it for a spin.

No account, no form: one tap and you are inside your own workspace, already stocked with a bookshelf and a kitchen so there is something real to poke at. It runs the newest build, usually hours old. Scan things, add things, break things. It deletes itself after an hour, and you can have your work emailed to you before it does.

Runs the nightly build, the same channel you can self-host. If something looks wrong or confusing, use the Feedback button in the corner to let us know.

Watch a yarn tracker get built from scratch.

Grace starts with an empty account and ends up with a working yarn tracker in about three minutes: she scans a ball of yarn, uploads a pattern, and the app works out what she needs.

No sound, just captions. Open it big

Then a Lego club, built into an app its members sign in to:

A Lego club gets its own member app Bjorn sets it up, then members sign in and land in their own app instead of an admin screen. 2:55

Or make your own.

The five setups above are bundles: a set of fields, a few saved views, and the things to watch for, installed in one click. And if yours isn't there, name the thing, pick the fields, and scan the first one. Same app.

Cobblr's bundle marketplace: a grid of ready-made bundles including Documents, Fasteners, Filament, Home Inventory, Medications, Pets, Plants, Subscriptions, Wardrobe, Warranties, Yarn, 3D Printers, Bookshelf, CNC Machines, Laser Cutters, Lego and Lending Library.

Things reach across to each other, too: a shelf that adds to the shopping list, a bin that prints its own label, a machine that logs its own service. The docs cover the wiring.
