Filament inventory for people who print
Know what's on every spool.
Filament and supplies, minus the busywork. Weigh it once, and the app keeps the number honest through every print.
Private beta
Not taking new accounts just yet. The demo is the real app with sample inventory, so you can see exactly what you'd be getting.

The demo workspace, exactly as visitors see it.
Mobile first
Made for the phone in your workshop.
Weigh, scan and ask from the shelf, one hand on the box. The desktop is the same app with more room, not a different one.



How it stays true
Inventory apps drift. This one is built not to.
Ground truth
The scale wins, always
Weigh a spool and that number is the truth. Estimates are estimates, and the app says so instead of pretending.
Event-sourced
Every gram is a ledger entry
Nothing edits a balance in place. Deductions, reweighs and corrections are events you can read back, print by print.
Watcher
Prints log themselves
A small daemon on your printers' network reports each finished job. Filament comes off the right spool with no typing.
Photo in, spool out
Point the camera at a label. The AI reads it, matches the catalog, and fills the form.
HueForge export
A contract-driven filament library with measured transmission distance — never a partial record.
Plan before you print
Load a sliced file and see whether the shelf can actually cover it, with a safety margin.
Supplies and upkeep
Nozzles, belts, desiccant. Service that consumes a part draws it down like anything else.
Labels and QR
Print a sheet, stick them on, scan to the spool. Works from a phone at the shelf.
Your data is yours
One-click takeout of everything, any time. Leaving never means losing it.
Ask first
Ask Filo before you sign up.
Filo is the assistant inside the app. This copy answers from a short list of notes rather than a model, so it knows what Spoolroom is and how it behaves, and nothing else. The real one reads your shelf.
This Filo knows the basics of Spoolroom and nothing about your shelf. Ask it what the app does, or pick one of these.
