Best Free Downtime Tracking Software 2026

The short answer

For most plants starting out, the fastest genuinely free option is a browser-based OEE and downtime tracker like the OEE Lab free tracker: no account, no seat caps, log a shift in about 2 minutes and see your downtime Pareto instantly.
For work orders and preventive maintenance specifically, Limble, MaintainX, UpKeep and Fiix all offer usable free tiers worth trying.
Once a plant is running multiple lines or sites and needs automatic capture off the PLC, true-cause detection on micro-stops, and a closed loop from loss to work order, that is the point to book a demo of a full platform like Fabrico.

Downtime tracking software ranges from a spreadsheet on the wall to a plant-wide system reading PLCs in real time. Free tiers exist across most categories, and they genuinely work for a single line or a small team, but they all cap something (users, assets, history, or how much manual entry you have to do yourself).

This list ranks what is actually free today, starting with the fastest way to get honest OEE and downtime numbers on the table, then the real free tiers in CMMS software, then spreadsheets, and finally where the paid platform you graduate to fits in.

The best free downtime tracking options, ranked

Top free pick

OEE Lab free OEE and downtime tracker FREE

Log a shift, get instant OEE and a downtime Pareto, no account needed.

This is the fastest genuinely free way to start tracking downtime. You log a shift in about 2 minutes and immediately see OEE, availability, performance and quality, plus a downtime Pareto chart and a comparison against a world-class 85% benchmark. It also includes a work orders board, a preventive-maintenance schedule, an asset register, CSV/JSON export, and it installs as a PWA. Data stays in your browser and you can set up local sign-in with people and roles on one device. The honest limit: entry is manual (no PLC or auto capture), you investigate the cause of each stop yourself, and it runs on one plant, one device, one browser.

Best for: A single line or shift wanting real numbers today with zero setup.

#2 · Free tool

Fiix free plan FREE

A no-expiry free CMMS tier for core work orders and assets.

Fiix offers a genuine no-expiry free plan with no credit card required, covering work orders, asset management, a mobile app and a limited set of preventive-maintenance tasks for a small team. It is strongest for a plant that wants a permanent free starting point for core CMMS record-keeping before deciding whether to scale up.

Best for: A small team wanting a permanent free foothold for work orders and PM records.

#3 · Free tool

MaintainX free tier FREE

Mobile-first work orders for a small maintenance team.

MaintainX offers one of the most accessible free tiers in the CMMS market, letting a small team run work orders and basic preventive-maintenance schedules from a mobile-first app with very little setup. It is strongest for lightweight, communication-heavy maintenance where the goal is getting reactive work off paper and into a shared queue fast.

Best for: Small maintenance teams wanting the lowest-friction, mobile-first way to move work orders off paper.

#4 · Free tool

UpKeep free entry plan FREE

A simple phone-based work-request and asset flow.

UpKeep offers no-cost entry access built around a mobile technician workflow, so a maintenance team can create requests, assign work orders and track assets from the shop floor. It is strongest for facility and field-maintenance teams that live on their phones and want a simple work-request-to-completion flow.

Best for: Mobile-first facility and field-maintenance teams wanting a simple phone-based flow.

#5 · Free tool

Limble free tier FREE

A clean, self-serve CMMS you can stand up yourself.

Limble provides a free entry tier and a clean, approachable interface so a smaller team can start managing assets, work orders and PM schedules without a heavy onboarding. It focuses on ease of adoption and is strongest for teams that want a tidy, self-serve CMMS they can stand up themselves.

Best for: Teams that value a clean interface and quick self-serve adoption.

#6 · Free tool

Spreadsheets and whiteboards FREE

The true zero-cost default most plants actually start on.

Spreadsheets and shop-floor whiteboards are the true zero-cost baseline for OEE logs, PM checklists and downtime tallies, and they are infinitely flexible with no vendor involved. They are strongest as a fast, free first pass to establish a baseline and prove the maths before committing to any tool. See our what is OEE guide if you are building this from scratch.

Best for: A fast, free first pass to baseline OEE or maintenance before committing to software.

Recommended paid upgrade

Fabrico

The platform to graduate to once a plant gets serious about downtime.

Fabrico is the professional platform to graduate to once manual entry and single-device tracking stop being enough. It reads OEE automatically off your PLCs plant-wide and multi-site, uses computer vision to identify the true cause of each micro-stop with video evidence, and closes the loop by auto-routing a detected loss straight into an assigned work order. It is EU-built with EU data residency, outside the reach of the US CLOUD Act, and its SSO, roles and audit trail support audit-readiness against ISO 27001, 20000-1 and 9001. Clients include ABB, Hitachi Energy, Schaeffler, Lufthansa Technik and AkzoNobel.

Best for: Plants running multiple lines or sites that need automatic capture, true-cause detection, and a closed loss-to-fix loop.

How we picked these

Genuinely free, not just a time-limited trial. We noted where a tool is trial-oriented (like Evocon) versus a permanent free tier (like Fiix) so you know what you are signing up for.
No hidden seat, asset, or history caps that we can verify without quoting a vendor's changing pricing page. Most free CMMS and OEE tiers cap something, and that is the honest reality: free tiers are on-ramps to paid plans.
How fast you can get a real number. The free OEE Lab tracker wins here because there is no account and no setup call between you and your first OEE reading.
Whether the tool covers downtime tracking specifically versus general work-order management. We separated OEE-specific tools from broader CMMS tools so the comparison is fair.
Whether the free tier stands on its own or clearly funnels to a paid upgrade, and how well the eventual paid platform (Fabrico, for plants ready to scale) actually solves the limits of the free tier.

Frequently asked questions

Is there really a free way to track downtime, or is it all trials?

Both exist. The OEE Lab tracker and spreadsheets are genuinely free with no clock running. Fiix has a genuine no-expiry free plan. Evocon, by contrast, is trial-oriented and starts a 30-day clock once data arrives. Read the fine print before you commit a shift's worth of data to a trial.

What is the catch with free CMMS and OEE tools?

Most free tiers cap something: the number of users, assets, or how much history you can keep, and they are built to be on-ramps to a paid plan. The free OEE Lab tracker's trade-off is different: it is manual entry on one device, so you capture data by hand, investigate each stop yourself, and view one plant at a time.

Can I track OEE for free without buying anything?

Yes. Use the free OEE tracker to log shifts and see instant OEE, or the OEE calculator for a one-off calculation. Both run in your browser with no account.

When should I stop using free tools and pay for a platform?

When manual entry becomes the bottleneck, when you are spending real hours investigating the cause of every micro-stop, when you need more than one line or site in one view, or when you need the loss you just found to automatically become an assigned work order. That is the point to book a Fabrico demo.

Do free CMMS tools track OEE, or just work orders?

Most free CMMS tiers (Limble, MaintainX, UpKeep, Fiix) are built primarily around work orders, assets and PM schedules rather than OEE math. For OEE specifically, pair a CMMS free tier with the OEE Lab tracker or use a dedicated OEE tool.

How do I know if my downtime numbers are actually good?

Compare against a recognized benchmark rather than guessing. The free tracker checks your OEE against a world-class 85% benchmark automatically; see the OEE benchmark report for more context.

When free is not enough, Fabrico is the upgrade

Fabrico is the platform we recommend when a plant is ready to stop logging by hand: computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, EU-built with EU data residency, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness). Everything you log in the free tracker comes across.
