Choosing a CMMS for your manufacturing plant is not a small decision. You're committing your team to a system they'll use every single day -- and if it doesn't stick, you're right back to WhatsApp and spreadsheets within six months.

Two platforms that come up often in manufacturing maintenance discussions are Fiix (owned by Rockwell Automation) and OpexMX. Both aim to solve the same core problem: getting maintenance work organized, tracked, and measurable. But they take very different approaches to how they get there.

This comparison is based on publicly available information as of 2026. We've done our best to be accurate, but pricing and features change -- always verify with the vendor before making a decision.

At a Glance

Fiix has been around since 2008 and was acquired by Rockwell Automation in 2020. It's positioned as a mid-market CMMS with a strong focus on integration with industrial automation systems. Fiix offers a free tier and scales up through per-user pricing. It's a solid, mature platform used by thousands of maintenance teams worldwide.

OpexMX is built specifically for manufacturing maintenance teams, with a focus on people-first adoption. It bundles gamification, a full LMS (Learning Management System), NFC asset scanning, and built-in team chat into a flat per-plant pricing model designed to make costs predictable regardless of team size.

Feature Comparison

Where OpexMX Wins

Gamification drives adoption. This is the single biggest differentiator. CMMS adoption failure rates hover around 70%, and the root cause is almost always that technicians stop using the system. OpexMX's built-in gamification -- points, leaderboards, achievements -- gives your team a reason to engage beyond "because management said so." For plants struggling with adoption, this is a game-changer.

Flat pricing saves money at scale. If you have more than 5 people on your maintenance team, Fiix's per-user model starts getting expensive fast. A 20-person team on OpexMX Professional costs $799/month. The same team on Fiix Professional would run $1,500/month. That's nearly double the cost for the same headcount.

Full LMS built in. Most CMMS platforms treat training as an afterthought -- maybe a checkbox for "certification expiry date." OpexMX includes a complete Learning Management System with course creation, approval workflows, qualification tracking, and completion records. This matters because training gaps are one of the leading causes of maintenance errors and safety incidents.

NFC for field verification. QR codes are great, but they require line of sight and good lighting. NFC tags can be read through cases, in the dark, and without aiming a camera. For technicians working in tight, poorly lit plant environments, NFC is a practical advantage. Every NFC scan is logged with an audit trail, so you know who was where and when.

On-premise deployment. Some industries -- food and beverage, pharmaceuticals, defense -- require or strongly prefer on-premise solutions for data residency and security compliance. OpexMX offers a standalone binary that runs entirely on your infrastructure. Fiix is cloud-only.

Built-in team chat and workflow builder. Instead of relying on a separate messaging app for coordination, OpexMX has real-time WebSocket chat built directly into the platform. The visual workflow builder lets you create step-by-step guided procedures that walk technicians through complex repairs. Neither of these is available in Fiix.

Where Fiix Wins

Free tier for small teams. If you're a small operation just getting started with structured maintenance, Fiix's free tier is genuinely useful. You can create work orders, track assets, and build a basic PM schedule without spending anything. OpexMX offers a free trial, but not a permanent free tier.

Rockwell ecosystem integration. If your plant already uses Rockwell Automation hardware and software, Fiix's integration with that ecosystem is a real advantage. Data can flow between your PLCs, sensors, and maintenance system. For Industry 4.0 environments built on Rockwell infrastructure, this matters.

Mature native mobile app. Fiix has invested heavily in its native mobile apps (iOS and Android), and the experience is polished. OpexMX is web-first with a responsive design, which works well but doesn't match the feel of a purpose-built native app.

Fiix Foresight AI. Fiix's AI capabilities, branded as Foresight, include predictive maintenance analytics that leverage machine learning on your historical maintenance data. It's a mature offering that goes beyond basic chat assistance.

Pricing Breakdown: 20-Person Team

This is where the difference becomes tangible.

Over a year, that's a difference of $8,412. Over three years, it's more than $25,000 -- enough to fund a significant equipment upgrade or training program.

Fiix does offer a lower-priced tier at $45/user/month, which would bring the 20-person cost down to $900/month. However, that tier lacks some of the features that make Fiix competitive (like advanced reporting and integrations), so the comparison isn't entirely apples-to-apples.

The Bottom Line

Choose OpexMX if you're serious about driving adoption through gamification, need a built-in LMS for technician training, want predictable flat pricing regardless of team size, or require on-premise deployment for compliance reasons. OpexMX is built for teams that want a system their technicians will actually want to use.

Choose Fiix if you're already invested in the Rockwell Automation ecosystem, need a free tier to get started, or want a mature native mobile app experience. Fiix is a proven platform with strong backing and solid integrations.

Both are legitimate choices. The right one depends on what matters most to your team.
