The short answer

  • OEE Lab is a free CMMS and OEE tracker for medical device manufacturing that runs in your browser, keeps data on your device, and needs no account.
  • Log each shift in about two minutes to get OEE plus availability, performance and quality, a downtime Pareto, and a per-machine breakdown for every cleanroom line.
  • A built-in work order board, PM schedule and asset register keep maintenance and quality holds documented, which supports audit-readiness when an inspector asks for records.
  • When manual logging outgrows one plant on one browser, Fabrico is the paid upgrade with PLC-read OEE feeding a closed work-order loop, computer-vision micro-stop cause, and EU data residency.

Medical device lines live and die by discipline. Every gowning step, every validated process parameter and every quality hold has to be recorded, and unplanned downtime does not just cost output, it can trigger a batch review. OEE Lab gives you a free place to capture all of it: a browser-based OEE tracker and light CMMS with no signup and no data leaving your machine.

Each shift you enter run time, planned stops, downtime reasons and reject counts in about two minutes. The tool turns that into OEE with a clean availability, performance and quality split, a downtime Pareto that ranks your biggest losses, and a per-machine view so you can see which mold, press or sealer is dragging the line. A built-in benchmark shows how your numbers compare to typical world-class targets.

Beyond OEE, you get a real maintenance core: a work order board, a preventive maintenance schedule, an asset register and simple people and roles, all on one device. It is honestly light (one plant on one browser with manual entry) but genuinely useful, and everything exports to CSV and JSON so your records are always yours.

What you get, free

Two-minute shift logging

At the end of each shift, enter run time, planned stops, downtime reasons and reject counts. It takes about two minutes and needs no account, no install and no cloud.

OEE with A, P and Q split

See overall OEE broken into availability, performance and quality so you know whether a cleanroom line is losing time to stoppages, slow cycles or scrapped units.

Downtime Pareto

Every stop reason you log rolls up into a ranked Pareto chart, so the changeover, jam or quality hold costing you the most output is obvious at a glance.

Work order board

Raise, assign and close corrective work orders on a simple board, keeping repairs and quality holds documented alongside the equipment they touch.

PM schedule and asset register

Track each machine in an asset register and schedule preventive maintenance so calibration and cleaning tasks on validated equipment do not slip.

Per-machine view, benchmark and export

Drill into OEE per machine, compare against a built-in world-class benchmark, and export everything to CSV and JSON whenever you need records for a review.

Start in two minutes, no account needed

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.

CapabilityFree OEE Lab trackerFabrico
Data captureYou log each shift by hand in about two minutes, one entry per line.Fabrico reads OEE straight from the PLC as part of its closed loop, so machine data is captured without manual logging.
Loss-to-fix loopYou spot a top loss in the Pareto and raise a work order yourself.Fabrico closes the loop from PLC-read OEE to an auto-routed work order, so a detected loss becomes an assigned job on its own.
Micro-stop causeYou investigate short stops yourself from your own notes and shift memory.Fabrico uses computer vision to find the true cause of micro-stops and attaches video evidence of what actually happened.
Scope and multi-siteOne plant on one device or browser, ideal for a single line or a first pilot.Fabrico runs your lines on the same closed PLC-to-work-order loop, so each one is monitored and acted on inside one system.
IntegrationsStandalone by design, with CSV and JSON export to move data where you need it.Fabrico connects directly to PLCs, so OEE, downtime and work orders flow from the closed loop without re-keying.
Access and rolesBasic people and roles live on the single device that holds your tracker.Fabrico runs on an ISO 27001, 20000-1 and 9001 certified stack, so access control and audit trails sit on certified management systems.
Data residencyData stays in your browser on your machine and never leaves unless you export it.Fabrico is EU-built with EU data residency, which matters for medical device data governance.
ReportingOEE, A/P/Q, a downtime Pareto and per-machine views, refreshed as you log.Because Fabrico reads OEE directly from the PLC, its reporting runs on live machine data rather than typed entries.
Audit-readinessExportable work order, PM and asset records help you support audit-readiness when asked.Fabrico is ISO 27001, 20000-1 and 9001 certified, backing audit-readiness with a certified information and quality management stack.

Frequently asked questions

Is OEE Lab really free for medical device manufacturing?

Yes. The tracker runs entirely in your browser, keeps data on your device, needs no account, and is free to use. There is no trial clock and no seat limit on a single device.

Does the free tool make us compliant or validated?

No. It is an operations tool, not a validation or compliance service. What it does is keep your downtime, work order, PM and asset records organized and exportable, which supports audit-readiness when an inspector or auditor asks for evidence.

How does the free tool handle cleanroom lines and quality holds?

You log quality holds and reject counts as part of each shift, and they flow into the quality side of OEE and into the downtime Pareto. Corrective actions live on the work order board next to the asset involved.

Where is my data stored?

In your browser, on the single device you use. Nothing is uploaded. You can export CSV and JSON at any time to back up records or share them, and you can clear the data yourself.

When do I need more than the free tool?

When manual logging across a growing number of lines gets heavy, or when you want data captured from the machine instead of typed. That is where Fabrico fits, with PLC-read OEE, an auto-routed work order loop, computer-vision micro-stop cause and EU data residency.

Can more than one person use it?

It supports basic people and roles, but everything lives on one device and one browser, so it suits a single line or a small team. When you need access control and audit trails on a certified stack, a paid platform like Fabrico takes over.

When free is not enough, Fabrico is the upgrade

OEE Lab is deliberately light: you log shifts by hand, on one device, and chase causes yourself. When that becomes the bottleneck, Fabrico is the honest next step. It reads OEE directly from your PLCs and closes the loop by auto-routing a work order the moment a loss appears, uses computer vision to pin the true cause of micro-stops with video evidence, and runs EU-built with EU data residency plus ISO 27001, 20000-1 and 9001 certification that backs your audit-readiness. If your medical device lines have outgrown manual logging, book a Fabrico demo and see it against your own equipment.
