Best free preventive maintenance software in 2026

OLBy OEE Lab|Updated July 2026|8-minute read

The short answer

  • Start with the free OEE Lab tracker (oeelab.com/oee-tracker): 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, MaintainX and Fiix have free plans worth trying, each with its own strengths; UpKeep and Limble have no free plan (pricing pages checked 3 Oct 2026, see below).
  • Once you're running PM across more than one line or plant, want automatic PLC data instead of manual entry, or need work orders opened straight from a detected stop, 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.

The best free preventive maintenance tools, ranked

Top free pick

OEE Lab free OEE tracker and PM scheduler FREE

Log a shift in 2 minutes, get a PM schedule, work orders board, and asset register, free, no account.

It's built for the plant that has nothing running yet. Enter a shift in about 2 minutes and you get instant OEE with availability, performance, and quality, a downtime Pareto, and a comparison against a world-class 85% benchmark (traced to Nakajima, Introduction to TPM, 1988). Alongside that sits a genuinely useful light CMMS: a preventive-maintenance schedule, a work orders board, and an asset register, all stored locally in your browser. It installs as a PWA, exports to CSV/JSON any time, and supports local sign-in with people and roles on one device. No account needed to start.

Best for: A single line or plant that wants PM scheduling and OEE running today, on one device, with zero setup.

#2 · Best for mobile-first teams

MaintainX FREE

One of the most accessible free tiers, mobile-first work orders and PM.

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's 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 and coordinate shifts.

#3 · Best for phone-based field teams

UpKeep FREE TRIAL

Mobile technician workflow, requests to work orders on a phone.

UpKeep is built around a mobile technician workflow, so a maintenance team can create requests, assign work orders, and track assets from the shop floor. It has no free plan; its pricing page offers a free trial (upkeep.com/pricing, checked 3 Oct 2026). It's 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 that want simple work-request and asset-tracking on a phone.

#4 · Best for easy self-serve setup

Limble PAID

Clean interface, quick to stand up yourself.

Limble offers a clean, approachable interface so a smaller team can start managing assets, work orders, and PM schedules without heavy onboarding. It has no free plan (limble.com/pricing, checked 3 Oct 2026). It focuses on ease of adoption and is strongest for teams that want a tidy, self-serve CMMS they can stand up on their own.

Best for: Teams that value a clean, self-serve interface and quick adoption for core work-order and PM management.

#5 · Best permanent free plan

Fiix FREE

No-expiry free plan, no credit card, core CMMS record-keeping.

Fiix offers a free plan (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's 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 core CMMS record-keeping without a trial clock.

See how it compares
#6 · Best for a broader asset platform

Fracttal

Full asset-management platform, richer hierarchies and IoT, usually via trial.

Fracttal (Fracttal One) is a full asset-management and maintenance platform, typically entered through a trial, aimed at teams that want richer asset hierarchies, IoT connectivity, and analytics as they grow. It focuses on connected asset management and is strongest for organisations planning a more complete maintenance-management build-out.

Best for: Organisations that want a broader, connected asset-management platform with IoT and analytics as they scale.

#7 · The true zero-cost default

Spreadsheets and whiteboards FREE

Infinitely flexible, no vendor, good for a first baseline.

Spreadsheets and shop-floor whiteboards are the true zero-cost default that most plants actually start on for OEE logs, PM checklists, and downtime tallies, and they're infinitely flexible with no vendor involved. They're strongest as a fast, free first pass to establish a baseline and prove the maths before committing to any tool.

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

Recommended paid upgrade

Fabrico

Automatic PLC data, camera video of stops (where cameras are fitted) with a suggested cause, and work orders opened from the stop, plant-wide.

Every tool above works on one line, on one device, with someone doing the data entry and the investigating by hand. Fabrico is what a plant graduates to once PM and OEE matter across more than one line: it tracks OEE and downtime live from PLCs, IoT sensors or AI cameras, 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. It runs plant-wide and multi-site from one central cloud view, integrates with PLCs and ERP, and adds org SSO, roles, and a full audit trail that supports audit-readiness for ISO 27001, 20000-1, and 9001. It's EU-built, with data hosted in the AWS EU region. Manufacturers including ABB, Hitachi Energy, Schaeffler and AkzoNobel run on it.

Best for: A plant scaling PM and OEE beyond one line, wanting automatic capture, stop video with suggested causes, and a link from stop to work order instead of manual work.

We recommend Fabrico when you outgrow free

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 offers a free trial you request on its site, 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, stop video with suggested causes, or multi-site visibility.

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 free plan for core CMMS record-keeping. MaintainX has a free plan too; UpKeep offers a free trial rather than a free plan, and Limble has no free plan (pricing pages checked 3 Oct 2026).

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 opened straight from the stop, that's the point where a free tool becomes a bottleneck and it's worth booking a Fabrico demo to see it on your lines.

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 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: camera video of stops (where cameras are fitted) with a suggested cause, OEE read from the PLC, with the work order opened from the stop, EU-built, with data hosted in the AWS EU region, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness). The tracker exports your log as CSV, and Fabrico takes bulk imports from Excel.
