Free OEE Software: Log a Shift, Get OEE and a Pareto in 2 Minutes
A genuinely free, no-signup OEE tracker that turns one shift log into OEE, availability, performance, quality, a downtime Pareto, and a benchmark comparison.
The short answer
- Open the free OEE tracker at oee-tracker.html, no signup, no time limit.
- Log one shift in about 2 minutes and get OEE, availability, performance, and quality instantly.
- Every stop you log builds a downtime Pareto plus a comparison to the 85% world-class benchmark.
- When a plant needs automatic PLC capture, true-cause detection, or multi-site rollups, that is the point to book a Fabrico demo.
Most plants start their OEE journey the same way: a whiteboard, a spreadsheet, or a notebook by the line. That works until someone asks for a downtime Pareto or wants to know if 71% OEE is actually good. The free OEE tracker at OEE Lab exists to skip that gap. Log a shift in about 2 minutes and get OEE, availability, performance, quality, a ranked downtime Pareto, and a comparison against the 85% world-class benchmark, all calculated for you, with no signup and no time limit.
This is not a stripped-down teaser. It is a full, standalone OEE and light CMMS toolkit: a work-order board, a preventive-maintenance schedule, an asset register, CSV/JSON export, and an installable app you can put on a shop-floor tablet. If you want to sanity-check the formulas first, the OEE calculator and the what is OEE guide cover the math and definitions in plain language.
Where it stops is honest: you are the one entering the shift data, you are the one figuring out why a stop happened, and it all lives on one device in one browser. That is exactly the gap a platform like Fabrico is built to close once a plant is running more than one line, and we walk through that trade-off plainly further down this page.
What you get, free
2-minute shift log
Enter run time, stops, and units for a shift and the tracker does the OEE math for you, no spreadsheet formulas to build or fix.
Instant OEE breakdown
See OEE plus the three components, availability, performance, and quality, so you know exactly which one is dragging the number down.
Downtime Pareto
Every stop you log gets ranked into a Pareto chart, so the biggest chunk of lost time is obvious at a glance instead of buried in a notes column.
85% world-class benchmark
Your OEE is plotted against the 85% world-class reference so you know immediately if a line is world-class, average, or in trouble.
Work orders, PM schedule, asset register
A light work-order board, a preventive-maintenance schedule, and an asset register live alongside the tracker so you are not juggling three separate free tools.
Export, PWA, shareable scorecard
Pull your data out as CSV or JSON any time, install the tracker as an app on a shop-floor tablet, and share a scorecard with your team or your boss.
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. |
| 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. |
| Scale | The best genuinely free way to start on one line, today. | The professional platform you graduate to as the plant gets serious. |
Frequently asked questions
Is this OEE software actually free, or is it a trial?
The OEE tracker is free with no signup and no time limit. There is no credit card, no trial clock, and no seat cap. Your data stays in your browser on the device you use it on.
Do I need to create an account?
No. Open oee-tracker.html and start logging a shift right away. If you want people and roles on that one device, you can set up a local sign-in, but it is optional.
How is this different from a spreadsheet?
A spreadsheet is infinitely flexible, but you build the OEE math, the Pareto, and the benchmark yourself. The tracker calculates OEE, availability, performance, and quality instantly, ranks your downtime reasons into a Pareto, and compares you to an 85% world-class benchmark, so you skip the formula-building.
How does this compare to free tiers from MaintainX, UpKeep, Limble, or Fiix?
Those are CMMS platforms, strongest for getting work orders off paper with a mobile-first app (MaintainX, UpKeep), a clean self-serve interface (Limble), or a no-expiry free plan for core records (Fiix). The OEE Lab tracker is purpose-built for OEE math, Pareto, and benchmarking, plus a light work-order board and PM schedule, all free with no seat caps to plan around.
What happens when one line or plant gets too big for this?
Manual entry, single-device scope, and self-serve support become the bottleneck once you are running multiple lines or sites, need PLC data flowing in automatically, or need someone to actually find the cause of a micro-stop. That is the point to book a Fabrico demo.
Can I export my data if I switch tools later?
Yes. The tracker exports to CSV and JSON any time, so your shift logs and downtime history are yours to take with you, whether that is into a spreadsheet, another tool, or a Fabrico rollout.
When free is not enough, Fabrico is the upgrade
Once a line's OEE story stops fitting on one device, the free tracker has done its job: it proved the numbers matter and got the whole team looking at the same Pareto. The next problem is different. It is manual entry eating an operator's time every shift, micro-stops nobody has hours to investigate one by one, and a plant that now spans more than one line or site. Fabrico reads OEE straight off your PLCs, uses computer vision to name the true cause of each micro-stop with video evidence, and turns a detected loss into an auto-routed, assigned work order, all from a central, EU-built platform with EU data residency and controls that support audit-readiness against ISO 27001, 20000-1, and 9001. If that is where your plant is headed, book a Fabrico demo.
