Best free preventive maintenance software in 2026
The short answer
- Start with the free OEE Lab tracker (oee-tracker.html): it gives you a PM schedule, a work orders board, and an asset register in your browser in about 2 minutes, no account and no seat limit to plan around.
- For a more traditional free CMMS with a mobile app, Limble, MaintainX, UpKeep, and Fiix all offer genuine free tiers worth trying, each with its own strengths (see below).
- Once you're running PM across more than one line or plant, want automatic PLC data instead of manual entry, or need a closed loop from a detected loss straight to an assigned work order, that's the point to book a Fabrico demo.
Every plant starts the same way: a spreadsheet, a whiteboard, or a notebook that tracks when the compressor was last serviced. It works until it doesn't, usually right when a machine goes down and nobody remembers if the filter was ever changed.
This list is built for that moment. It ranks the genuinely free ways to run preventive maintenance in 2026, starting with a free browser-based PM tracker you can open right now, then the real free tiers from established CMMS vendors, then the honest reality of what "free" caps and what it's an on-ramp to.
None of these free tools do everything. That's the point. We tell you exactly where each one stops, so you know when it's time to graduate rather than fighting the tool.

At a glance
| Capability | Free tools (OEE Lab tracker etc.) | 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. |
| Security posture | Data stays local in your browser, on the device you use. | SSO, roles, and audit trail that support audit-readiness (ISO 27001, 20000-1, 9001). |
| Data residency | Your data lives in your own browser storage on your device. | EU-built with EU data residency, outside the reach of the US CLOUD Act. |
| 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. |
| Benchmark and scorecard | Compare to a world-class 85% benchmark and share a scorecard. | Continuous multi-site benchmarking with drill-down to line and asset. |
| Support and onboarding | Self-serve, start free with no account and no setup call. | Guided onboarding and ongoing support from the Fabrico team. |
| Scale | The best genuinely free way to start on one line, today. | The professional platform you graduate to as the plant gets serious. |
How we ranked these
- Genuinely free, not a disguised trial: we checked whether the free tier has a hard expiry, and called that out where it applies (for example Evocon's OEE offering is trial-oriented rather than a permanent free tier, so it's mentioned for context rather than ranked here).
- No account needed to get value: the OEE Lab tracker ranks first partly because you can log a shift and see OEE before creating any account at all.
- Real PM functionality, not just a calculator: tools had to support an actual PM schedule, asset register, or work order board, not just a one-off number.
- Honest about limits: most free CMMS tiers cap something, whether that's users, assets, history, or device scope. We say what each one focuses on instead of pretending it's unlimited.
- Clear upgrade path: we only recommend Fabrico where a plant has genuinely outgrown a single-line, single-device tool and needs automatic capture, true-cause detection, or multi-site visibility.
The OEE Lab tracker logs a shift and shows your OEE, your loss Pareto and a world-class benchmark in about two minutes, with work orders and preventive maintenance in the same place. No account needed.
Frequently asked questions
Is there really a 100% free preventive maintenance tool, with no trial and no credit card?
Yes. The OEE Lab free tracker needs no account and no credit card to log a shift, run a PM schedule, and track assets, and Fiix offers a no-expiry free plan for core CMMS record-keeping. Most other free CMMS tiers (Limble, MaintainX, UpKeep) are genuine free tiers too, though they typically cap users, assets, or history rather than being time-limited trials.
What's the catch with free preventive maintenance software?
The catch is almost never hidden, it's structural: free tiers usually cap the number of users, assets, or months of history you can keep, and they're built as an on-ramp to a paid plan once you outgrow that. The OEE Lab tracker takes a different shape: it doesn't cap history or assets, but it's standalone, on one device, and you do the data entry and the investigating yourself.
Can free PM software replace a full CMMS for a growing plant?
For a single line or shift, yes, often for quite a while. Once you're coordinating PM across multiple lines or sites, want automatic PLC data instead of manual shift entry, or need work orders to route themselves the moment a loss is detected, that's the point where a free tool becomes a bottleneck and it's worth booking a Fabrico demo to see the closed-loop version.
How is the OEE Lab tracker different from a free CMMS trial like Evocon's?
Evocon's free offering is OEE-specific and trial-oriented, the clock starts once data arrives. The OEE Lab tracker has no clock: it's a permanent free browser tool for OEE plus a light PM schedule, work orders board, and asset register, with your data staying in your browser rather than expiring.
What should I track first if I have nothing running today?
Start by logging one shift in the free OEE tracker to get a baseline OEE number and see your downtime Pareto. Once you know your biggest loss category, use the downtime cost calculator to size what it's actually costing, then build your PM schedule around the assets driving that loss.
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.
