Free OEE Monitoring Software: Watch Your OEE Trend Shift Over Shift
Log each shift in about 2 minutes and watch OEE, availability, performance, and quality move on a live trend line, with a downtime Pareto, a target, and shift streaks. No account, no time limit, and your data stays in your browser.
The short answer
- Open the free OEE monitoring tracker at oeelab.com/oee-tracker, no account and no time limit.
- Log each shift in about 2 minutes and watch OEE, availability, performance, and quality move on a running trend line.
- Set a target, build shift streaks above it, and let every logged stop stack into a live downtime Pareto and per-machine breakdown.
- When you need continuous monitoring, tracked live from your PLCs across several lines, that is the point to book a Fabrico demo.
A one-off OEE number tells you how yesterday's shift went. Monitoring tells you where the line is heading. The free OEE tracker at OEE Lab is built for the second job: log each shift in about 2 minutes and it plots OEE, availability, performance, and quality on a running trend line, so a slow drift shows up long before it becomes a bad month. No account, no time limit, and your data stays in the browser on your device.
Monitoring is only useful if it points at something. Every stop you log stacks into a live downtime Pareto, so the reason eating the most time stays at the top of the list shift after shift. Set a target, watch the streak of shifts above it, and open the per-machine breakdown to see which asset is dragging the plant number down. If you want the definitions behind each metric, the maintenance KPI guide covers availability, performance, and quality in plain language.
The honest limit is that this is manual monitoring: you enter the shift data, you decide why a stop happened, and it all lives on one device in one browser. That is enough to make a trend visible and to get a whole team looking at the same chart, and for a single line it is genuinely all you need. Continuous, automatic monitoring that reads OEE straight off the machines and spans several lines is a different job, and further down we lay out plainly where the free tracker stops and where Fabrico takes over.
What you get, free
Shift over shift trend line
Each logged shift adds a point to a running trend for OEE and its three losses, so a gradual slide is obvious on the chart instead of hidden between two spreadsheet tabs.
OEE with A, P, and Q split out
Every reading breaks OEE into availability, performance, and quality, so you can see which of the three is moving and where to look first, not just that the headline number changed.
Live downtime Pareto
Log a stop with its reason and it stacks straight into a Pareto that reorders itself as the data grows, keeping your biggest recurring loss at the top of the list.
Target line and shift streaks
Set the OEE target you are chasing and the tracker marks every shift above it, so a team can watch a streak build and feel the trend instead of arguing about one bad day.
Per-machine breakdown
Split the plant number by asset to see which machine is pulling the average down, then follow that one line's own trend instead of guessing from the blended figure.
Export and world-class benchmark
Compare your OEE against the 85% world-class reference (traced to Nakajima, Introduction to TPM, 1988) to see how far you have to go, and pull the full history out as CSV or JSON any time to share it or archive it.
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 |
|---|---|---|
| Monitoring cadence | You watch the trend by logging each shift by hand, so the picture refreshes about once a shift. | Reads OEE continuously off your PLCs, so the trend is live and updates in real time without anyone typing. |
| Data capture | Enter run time, stops, and units for each shift in about 2 minutes; the data stays in your browser. | Tracks OEE and downtime live from PLCs, IoT sensors or AI cameras, while the line runs. |
| Micro-stop cause | You investigate short stops yourself and type in the reason you find. | Where cameras are fitted, the video of a stop sits next to its machine data, with AI-suggested likely causes the team validates. |
| From loss to fix | You spot a loss on the trend, then raise the work order yourself on the board. | A technician opens the work order from the detected stop, in the same system. |
| Scope and multi-site | One plant on one device and browser, best for a single line or shift. | Monitors every line and every site from one central cloud view. |
| Integrations | Runs standalone; you export the data when you want it somewhere else. | Connects to PLCs and ERP so OEE flows through your existing stack. |
| Access and roles | A local device sign-in holds people and roles on that one device. | Org SSO with roles across the plant and a full audit trail. |
| Data residency | Everything stays in your own browser storage, on your own machine. | EU-built, with data hosted in the AWS EU region and ISO 27001, 20000-1, and 9001 certification that supports audit-readiness. |
| Reporting | Live on-screen trend, the A/P/Q split, a downtime Pareto, and CSV/JSON export you run yourself. | Plant-wide live dashboards and reports to the people who need them. |
Frequently asked questions
Is this OEE monitoring software really free?
Yes. The OEE tracker is free with no signup and no time limit, no credit card and no seat cap. Your shift history and trend line stay in your browser on the device you use.
Do I need an account to monitor OEE?
No. Open oeelab.com/oee-tracker and start logging shifts right away. A local sign-in for people and roles on that one device is optional, not something you need to watch the trend.
How is monitoring different from a one-off OEE calculator?
A calculator answers one shift and forgets it. Monitoring keeps every shift, so OEE, availability, performance, and quality build into a trend you can read over days and weeks, with a target line and a running downtime Pareto instead of a single figure.
How often does the trend update?
The trend updates each time you log a shift, which takes about 2 minutes. This is manual monitoring, so the cadence is one point per shift rather than a live feed; for a continuous real-time reading you would move to an automatic, PLC-connected platform.
Can I monitor more than one machine?
Yes. Register your assets and the tracker splits OEE by machine, so you can follow each line's own trend and see which one is pulling the plant average down, all on the same device.
When do I need more than the free monitoring tool?
Once you need continuous monitoring read straight off your PLCs, coverage across several lines or sites, or someone to actually pin down the cause of a micro-stop, manual single-device logging becomes the bottleneck. That is the point to book a Fabrico demo.
When free is not enough, Fabrico is the upgrade
Manual monitoring does one job well: it proves the trend matters and gets everyone watching the same line. The next problem is a different one. It is an operator retyping numbers every shift, micro-stops nobody has time to chase one at a time, and a plant that now runs more than one line. Fabrico reads OEE continuously off your PLCs, puts the video of a stop next to its machine data where cameras are fitted, with AI-suggested likely causes, and lets a technician open the work order from the stop, all from a central, EU-built platform with data hosted in the AWS EU region and ISO 27001, 20000-1, and 9001 certification that supports audit-readiness. If that is where your line is heading, book a Fabrico demo.
