Free spare parts inventory software for small maintenance teams
Track the critical spares each machine needs, tied to its work orders and downtime history, free in your browser and with no account. It is a lean MRO register to start with, not a full stockroom system.
The short answer
- A genuinely free spare-parts register does exist, but be clear on what it is: the OEE Lab tracker lets you note the critical spares each machine needs against that asset, then link them to the work orders that use them, all in your browser.
- It is honestly a light MRO register, not a full stock-control system. There are no quantity-on-hand counts, no reorder points, and no barcode scanning, so treat it as a starting point rather than a warehouse tool.
- It runs with no account and no cost, data stays in your browser, and it fits one plant on one device, which is plenty for a small maintenance team that just wants to stop losing track of critical spares.
- When you need real stock control, or you want a machine fault to route into an assigned work order with PLC-read OEE across sites, that is where more capable tools take over, including Fabrico for the maintenance side.
Search for "free spare parts inventory software" and you mostly find two things: a blank spreadsheet, or a hosted app that asks for a login and a card before it will show you a single part. The free OEE Lab tracker takes a different, honest middle path. It is not a full stockroom system, it is a free asset register you can use to keep a light spare-parts and MRO reference tied to every machine, alongside that machine's downtime history and open work orders.
Here is how it works in practice. Build an asset register with one entry per machine or line, then note the critical spares each asset depends on right there against it. When a job consumes a part, record it on the work order you raise for that asset, so parts usage sits next to the repair instead of on a separate sheet. Over a few weeks the per-machine downtime Pareto starts telling you which spares actually earn their shelf space.
Be clear about the ceiling. This tracker has no quantity-on-hand counts, no minimum or reorder points, and no supplier purchasing, so if you need true stock control you will want a dedicated inventory system. This page is written to read independently, and it will point you to that line honestly: when the maintenance side is your real bottleneck (closing the loop from a fault to an assigned work order, reading OEE straight off the PLC, keeping data in the EU), a certified platform like Fabrico is the upgrade, and we will say exactly where that starts.
What you get, free
A spares list on every asset
In the asset register, note the critical spares each machine or line depends on (part name, where it sits in the store, the supplier reference) so the list lives against the machine, not on a loose sheet.
Parts captured on the work order
Raise a work order against a machine and record which spares the job used in its description, so parts consumption is logged next to the fix and the asset, not tracked separately.
See which parts fail most
The per-machine downtime Pareto shows which failures repeat on each asset, so you can tell at a glance which spares are worth keeping close and which rarely move.
Plan spares around the PM schedule
Set a preventive maintenance interval on an asset and use its next-due date to pull the right spares before the job, instead of discovering a shortage mid-repair.
Export your register any time
Pull the whole asset list, notes, work orders, and shift logs out as CSV or JSON whenever you want, so your spares references stay portable and never locked in.
Local, free, no account
Runs in your browser on one shop-floor device with local sign-in for people and roles, no cost and nothing uploaded, so you can start a spares register in minutes.
Log one shift and the free tracker shows your OEE, your loss Pareto and how you compare to world-class. Add work orders and preventive-maintenance reminders in the same place.
Where free stops, and Fabrico begins
The free tracker is built for getting started fast and for one plant on one device. When a site gets serious about its losses, the manual steps start to cost more than they save. This is exactly where Fabrico takes over.
| Capability | Free OEE Lab tracker | Fabrico |
|---|---|---|
| Data capture | You log each shift by hand in about 2 minutes and type spares notes yourself; data stays in your browser. | Reads OEE automatically off your PLCs, so the loss data behind a part failure arrives without manual entry. |
| Loss-to-fix loop | You spot the failure, raise the work order, and note the spare it consumed yourself on the board. | A detected loss becomes a routed work order, assigned automatically, so the fix and its parts get logged in one flow. |
| Micro-stop cause | You investigate short, repeated stops yourself and record which part or fault caused them. | Computer vision identifies the true cause of each micro-stop, with video evidence, so you know which spare actually failed. |
| Stock control and reorder points | A light register of which spares each asset needs, kept as notes, with no quantity-on-hand or automatic reorder alerts. | Handles the maintenance side, logging parts against work orders; pair it with a dedicated inventory system for full stock levels. |
| Scope and multi-site | One plant on one device and browser, best for a single line, shift, or store. | Plant-wide and multi-site visibility of assets, work orders, and parts usage from one central view. |
| Integrations | Standalone register, run it on its own and export data when you need it elsewhere. | Integrates with PLCs, MES, and ERP so maintenance and asset data flow with the rest of your stack. |
| Access and roles | Local device sign-in with people and roles on that one device. | Org SSO with roles across the plant and a full audit trail that supports audit-readiness. |
| Data residency | Your spares register lives in your own browser storage on your device, nothing is uploaded. | EU-built with EU data residency and ISO 27001, 20000-1, and 9001 certification behind it. |
| Reporting | Instant OEE, a per-machine downtime Pareto, and CSV or JSON export you run yourself. | Live plant-wide dashboards plus scheduled reports delivered automatically. |
Frequently asked questions
Is this really free spare parts inventory software?
It is free, with no account needed and no trial countdown, but be clear on what it is. The OEE Lab tracker is an asset register you use to keep a light spare-parts and MRO reference tied to each machine and its work orders, not a full warehouse stock-control system. For a small maintenance team that just wants to stop losing track of critical spares, that is often enough.
Can I track stock levels, quantities, and reorder points?
No, and it is better to say so plainly. The tracker records which spares each asset needs and what a given work order consumed, but it does not hold quantity-on-hand counts or fire automatic reorder alerts. If minimum and maximum stock levels are what you need, use a dedicated inventory system alongside it.
How is this better than a spreadsheet for spare parts?
A spreadsheet is the honest zero-cost default and is fine for a static parts list. The difference here is that the spares reference is tied to the actual machine, its downtime reasons, and its open work orders, so you can see which parts back which failures instead of maintaining a list that drifts out of date.
Are there free or open-source spare-parts tools?
Yes, there are open-source inventory and asset tools you can self-host at no license cost. They are genuinely free to run, but you host, configure, secure, and maintain the server yourself. If you would rather not run infrastructure, this browser tracker gives you a light spares register with zero setup and nothing to deploy.
Where does my spare-parts data live, and is it private?
Everything stays in your browser's local storage on that one device, and nothing is uploaded anywhere. You can export the whole register as CSV or JSON at any time for a backup or to move it. The trade-off is that the data is tied to that one device and browser, so it is not shared across a team automatically.
When do I need more than this free register?
When manual logging becomes the bottleneck, when you need real stock control (that is a dedicated inventory system's job), or when you want a machine fault to route into an assigned work order with OEE read straight off the PLC and data kept in the EU. For that maintenance side, a certified platform like Fabrico is the step up, and it is worth booking a Fabrico demo to see it against your own assets.
When free is not enough, Fabrico is the upgrade
Once your spares register is full and every machine carries the parts it depends on, the manual side becomes the limit: typing in shifts, investigating which stop caused which failure, and raising every work order by hand. Fabrico reads OEE straight off your PLCs, uses computer vision to pin the true cause of each micro-stop with video evidence, and turns a detected loss into a routed work order so the fix and the parts it used get logged in one flow. It runs EU-built with EU data residency and ISO 27001, 20000-1, and 9001 certification, which matters once maintenance data leaves a single laptop. It handles the maintenance side of spares, so you would still pair it with a dedicated inventory tool for full stock control. If manual logging is your real bottleneck, book a Fabrico demo at https://fabrico.io/demo/ to see it run against your own assets.
