Free CMMS for Small Manufacturers: Track OEE and Maintenance Without a Budget Line
A real, no-cost OEE tracker and light CMMS built for a single line or small plant, no account, no seat caps, no clock running out.
The short answer
- OEE Lab's free tracker logs a shift in about 2 minutes and gives you instant OEE, availability, performance, and quality, plus a downtime Pareto, work orders, PM schedule, and asset register, all in your browser.
- Most other "free" CMMS tiers (Limble, MaintainX, UpKeep, Fiix) are genuinely useful on-ramps, but they typically cap users, assets, or history and are built to convert you to a paid plan.
- The free tracker is the best zero-cost way to start on one line today. It is built for a single line or small plant, not for multi-site, PLC integration, or automatic root-cause detection.
- When a plant is running multiple lines or sites and needs automatic capture and true-cause detection, that is the point to book a Fabrico demo.
Small manufacturers usually start maintenance tracking the same way: a whiteboard, a spreadsheet, or a notebook by the line. It works until it doesn't, usually right when a stop repeats for the third time and nobody remembers what fixed it last time. A free CMMS closes that gap without asking for a budget approval first.
OEE Lab's free OEE tracker was built for exactly this stage: one plant, one device, a shift supervisor who needs numbers now, not after a software evaluation. It sits next to a light CMMS, a work orders board, a preventive-maintenance schedule, and an asset register, so you are not juggling three different tools to answer "why did we lose two hours yesterday."
If you want to see where your numbers sit before you touch a tool, run the OEE calculator or the downtime cost calculator first. Both take a couple of minutes and give you a baseline to track against.
What you get, free
2-minute shift logging
Enter run time, stops, and units at the end of a shift and get OEE broken into availability, performance, and quality immediately, no spreadsheet formulas to babysit.
Downtime Pareto and 85% benchmark
See which stops actually cost you the most time, ranked, and compare your OEE against a world-class 85% benchmark so you know if a number is actually good.
Work orders board and PM schedule
Raise a work order the moment you spot a loss, and keep a preventive-maintenance schedule and asset register so recurring jobs don't rely on someone's memory.
Local sign-in with roles, no account needed
Add people and roles on the device you use it on, no company account, no email verification, no setup call, just open it and start.
Installable PWA that keeps your data local
Install it like an app on a shop-floor tablet or laptop. Your data stays in the browser on that device, nothing uploaded anywhere by default.
CSV/JSON export and a shareable scorecard
Pull your data out whenever you want for a spreadsheet or a report upstream, and share a scorecard view with a manager without giving them the whole tool.
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 | Log each shift by hand in about 2 minutes, data stays in your browser. | Reads OEE automatically off your PLCs, no manual entry. |
| Micro-stop cause | You investigate sub-5-minute stops yourself and note the reason. | Computer vision identifies the true cause of each micro-stop, with video evidence. |
| Loss-to-fix loop | You spot the loss, then raise the work order yourself on the board. | A detected loss becomes an auto-routed work order, assigned automatically. |
| Scope and multi-site | One plant on one device and browser, best for a single line or shift. | Plant-wide and multi-site from one central cloud view. |
| Integrations | Standalone, run it on its own, export data when you need it elsewhere. | Integrates with PLCs, MES, and ERP so OEE flows with 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. |
| Data residency | Your data lives in your own browser storage on your device. | EU-built with EU data residency, outside the reach of the US CLOUD Act. |
| Reporting | Instant OEE, availability, performance, quality, a downtime Pareto, and CSV/JSON export you run yourself. | Live plant-wide dashboards plus scheduled reports delivered automatically. |
| Support and onboarding | Self-serve, start free with no account and no setup call. | Guided onboarding and ongoing support from the Fabrico team. |
Frequently asked questions
Is the OEE Lab tracker really free, no trial and no credit card?
Yes. There is no account required to start and no trial clock. It runs in your browser and your data stays on your device. You can install it as a PWA and keep using it indefinitely.
How is this different from Limble, MaintainX, UpKeep, or Fiix's free tiers?
Those are real CMMS products with genuinely useful free tiers. MaintainX and UpKeep are strongest for mobile-first work orders, Limble focuses on a clean self-serve setup, and Fiix is built around core maintenance record-keeping. All of them are on-ramps to a paid plan and typically cap users, assets, or history as you grow. OEE Lab's tracker is narrower, OEE plus a light CMMS, with no seat cap for a single small plant.
Can I track more than one line or shift with the free tracker?
Yes, for one plant on one device. It is built for a single line or a small plant running on one browser. If you are coordinating multiple lines or sites and need a central view, that is where a platform like Fabrico takes over.
Does the free tracker tell me why a machine stopped?
It gives you a downtime Pareto so you can see which stop reasons cost the most time, but you enter and investigate the cause yourself. Fabrico's computer vision identifies the true cause of sub-5-minute micro-stops automatically, with video evidence, which is usually where the biggest hidden losses live.
When should a small manufacturer move off a free CMMS?
When manual entry starts costing more time than it saves, when the same micro-stop keeps repeating and nobody can pin the cause, or when you add a second line or site and need one view across all of it. That is the point to book a Fabrico demo and see automatic PLC capture and the closed loss-to-work-order loop.
Is my data safe if I use a free browser-based tool?
Your data stays in your browser's local storage on the device you use, nothing is uploaded by default. That is fine for a single plant getting started. Once you need org-wide SSO, roles, and an audit trail that supports audit-readiness (ISO 27001, 20000-1, 9001), that is a platform-level feature, which is what Fabrico is built for.
When free is not enough, Fabrico is the upgrade
The free tracker is the right tool for one line and one person keeping it honest by hand. Once a plant is running multiple lines or sites, chasing the same micro-stop every week, or needs OEE numbers that flow straight into a work order without someone typing it in, that manual step becomes the bottleneck. Fabrico reads OEE automatically off your PLCs, uses computer vision to find the true cause of sub-5-minute stops with video evidence, and closes the loop by auto-routing a detected loss into an assigned work order, all from one EU-built, EU-hosted view across every site. Book a Fabrico demo to see it running on a line like yours.
