Modular apps for people whose workflows don't fit a SaaS template
Track your stuff. Plug in the bits you need: inventory, locations, labels, machines, schedules. Skip the bits you don't. Then wire them together so they actually talk. No code.
We cobbled this together because nothing else fit. Turns out a lot of people have that problem.
Better than a home-inventory app, on this combo alone.
A skein of yarn. A brake caliper. A Lego set. Every app that tracks them is secretly the same app: a list of things, with fields, units, and photos. The only real difference is the costume, and store-bought apps come dressed in someone else's.
Same row. Three costumes. That's the whole trick.
So the perfect niche app you can't find isn't missing. It just isn't dressed yet. Cobblr hands you the plain list and you dress it yourself: a dye lot on the yarn, a torque spec on the caliper, a shelf slot on the spice jar. With Cobblr, this takes a few clicks, not a developer.
Every one of these is a real, working app built by cobbling pieces together.
Scan a barcode and the make, model, and photo fill themselves in. Print a sticker for every bin, scan it with your phone, see what's inside. Then it tracks warranties, puts renewal dates on your calendar, and shares a read-only view with your insurer. Same sticker.
Your whole fleet, the builds in flight, the parts they eat, and the upkeep each machine is due for. It sends jobs to the printers and throws a live status board on the wall. The app that runs a 30-machine shop.
Run out of milk → it's on the list. Check it off → the fridge refills. A grocery order arrives → it logs the spend on a chart that trends like a fitness goal. Three things that never heard of each other.
Scan a box and the catalog fills in the name, photo, and year. Share a read-only wiki with friends: photos shown, what you paid hidden.
Log a repair you did yourself and it decrements the parts you used from stock. The next service lands on your calendar before it lapses.
Members log into a themed app you built, with the buttons you chose and the permissions you set. Not a spreadsheet. A university Lego club runs on this.
Each plant knows its zone and how often it drinks. When one's due, Cobblr tells Home Assistant to run that zone for the right number of seconds. Cobblr decides; your controller opens the valve. The to-do list that commands a sprinkler.
The part a spreadsheet (or any single-purpose app) never could. A connection is a sentence you click together:
You never have to touch these. But the day you want milk to add itself to the list, it's three clicks, not code. And a few of them add up fast:
Milk hits zero → it's on your shopping list → you check it off → the fridge count goes back up. No code. Two clicks to set up.
A $4.50 grocery order arrives → it restocks the milk and logs $4.50 onto a "grocery spend" chart, even though groceries and spending are two separate pieces that never knew about each other.
Type "millennium" → pick 75192 · Millennium Falcon → name, image, year, and theme fill in from a database of 27,000 sets. Adding inventory is a search, not a form.
Cobblr doesn't drive your 3D printer or flip your lights. That hardware already runs its own software. Cobblr is the layer above it: it decides what and when, keeps the record, and sends the command to whatever does the work.
That boundary is the whole point. It's why your to-do list can send a job to your printer, and why your plant collection can water its own garden, each plant on its own schedule. One brain over all your disjointed systems.
Those are a database and a doc that you turn into an app by hand. A spreadsheet can't print a QR label, scan a barcode, put a date on your calendar, or send a job to a machine. Cobblr does all four. They're modules, not formulas.
Opposite ends. Home Assistant runs your hardware in real time; Cobblr is the system of record above it (what you own, what it needs, what's scheduled) and it talks to Home Assistant to send commands and read data. They pair; they don't compete.
Each of those is one point. Cobblr is the one tool that becomes any of them, and then connects them. You don't install five apps that don't talk; you cobble together one that does.
Not if you start with a flagship bundle. Pick what you care about (Yarn, Home inventory, Pet care) and one click sets it all up: the right fields, the right units, and a saved view, pinned. Pick "Yarn" and you get colorway, fiber, weight and dye lot, "brand" and "price per skein" already relabelled, and a "My yarn stash" view grouped by weight class, in under a minute. Add your first skein and you're set. Power is opt-in; most people never touch a wire.
31 ready-made bundles for the usual stuff.
One click installs the fields, the units, and a pinned view. You're adding your first item in under a minute.
Install adds only what the bundle brings; uninstall takes only that away. Anything you customize on top stays yours.
Or skip the picking entirely (bring your own AI)
Type that, and Cobb cobbles the bundle together: your fields, your units, a view.
He checks it works, then shows you the change before it lands, so you can say no.
Bring your own key: Claude, OpenAI, or a local Ollama. It's your account, not a quota.
The same key reads a forwarded store receipt into inbox items and names the things you photograph.
No AI connected? Everything else on this page still works.
Turn on what you need: inventory, locations, labels, machines, schedules. Ignore the rest. Or describe what you track and let your AI pick.
Add your own fields, units, and views. A "dye lot" on yarn, a "shelf slot" on spices, a "warranty expires" date that lands on your calendar.
Click the sentence; it runs itself from then on.
