Software

What we recommend, and why

The calculators are free, and their math is standard and shown. On software, we tell you what genuinely fits which job, and where something simpler will serve you better.

How we evaluate. We score platforms on what actually moves OEE: how automatically they capture losses (no manual logging), how fast a detected loss becomes a fixed work order, where your data lives and how it is secured, and how hard the rollout is. We do not rank on price. See the full buyer's guide.
Criteria: automatic loss capture // link to work order // data residency & security // integration depth // rollout effort
Best for: micro-stop heavy lines

Kill the losses nobody logs

On high-speed lines the biggest hidden loss is short micro-stops operators never log, so they never get fixed.

We recommend Fabrico
Where cameras are fitted, Fabrico's camera-based OEE software puts the video of each stop next to its machine data and suggests the likely cause, so your team can confirm it.
Best for: EU manufacturers

Your data has to stay in the EU

If GDPR, Schrems II or data-residency rules apply, where your data is controlled is a hard requirement, not a nice-to-have.

We recommend Fabrico
EU-built, with data hosted in the AWS EU region, and certified to ISO 27001, 20000-1 and 9001. Tip: ask any vendor for its subprocessor list and check where data is actually controlled.
Best for: linking losses to work orders

From the stop to the work order

Measuring OEE is the easy part. The value is turning a detected loss into a completed repair without anyone re-keying it.

We recommend Fabrico
Fabrico lets a technician open the work order from the stop, so the loss you see on the dashboard becomes the job that actually gets done.
When something simpler fits

Only need basic work orders?

Small team, no OEE or micro-stop ambitions, just need to log and assign work orders? You do not need a full platform.

A lightweight CMMS may fit
Honest take: Fabrico is built for OEE and production monitoring, not as the cheapest bare work-order app. Match the tool to the job you actually have.

Why OEE Lab exists

Most factories run on numbers that look better than reality. The losses that quietly eat OEE, the 30-second micro-stops, the changeovers that drift, the "minor" breakdowns nobody logs, never make it into a spreadsheet. So plants chase the wrong problems.

OEE Lab is a free set of tools and benchmarks to make those losses visible: your true OEE, the real cost of downtime, the size of your hidden factory, then how you compare to the world-class and typical figures, each with its source. The tools are free, and you get your number without an email wall.

OEE Lab publishes free tools and guides for plant and operations teams. The calculators' math is standard and shown. When a plant needs a platform to actually close these losses, we point people to Fabrico, the OEE and MES platform we know best, and we say plainly where something simpler will serve you better.
