Asset maintenance management system open source

Gone are the days when maintenance management software was only available to enterprise companies with huge O&M budgets. Today, businesses that don’t have the budget for paid software subscriptions can seek out open-source maintenance management software options.

Over the past several years, work order software providers have transitioned from clunky, onsite hardware to affordable, cloud-based platforms. The result? Small businesses can now enjoy the same capabilities—creating digital work orders, cataloging asset data, tracking spare parts, and monitoring time and cost metrics—without the hefty price. 

Maintenance management software increases productivity and improves operations by centralizing tools, processes, and schedules involved in running preventive maintenance (PM) programs. Mobile CMMS software providers like MaintainX offer full-stack solutions designed to help operational managers reduce downtime, extend equipment lifecycles, and enhance supply-chain control. 

Are you wondering what your best free options are for keeping tabs on equipment maintenance?  If so, you’re in luck! Below we’ve compiled a list of the best free and open-source maintenance management software packages currently available. Before we dive into our recommendations, let’s take a closer look at open-source maintenance management software. 

What Is Open-Source Maintenance Management Software? 

open source maintenance management software

Open-source software (OSS) is developer-distributed software intentionally published with source codes to allow users to modify program functionality at no cost. 

Programmers can make changes to open-source software, including fixing bugs, improving features, enhancing usability, and applying various customizations. 

The Open Source Initiative (OSI) is a global authority on OSS and develops the criteria for classifying software as open source. For a software product to be considered open source, its license must include all of the following user rights:

  • Zero restrictions on redistributions
  • Source code must be included in the software package
  • Freedom to modify and make improvements to the software
  • Freedom to study how the software works
  • Freedom to use the software for any purpose 

With that said, open-source maintenance management software is a form of open-sourced software built for O&M task automation. Essentially, it’s a computerized maintenance management system (CMMS) that doesn’t require any corporate licensing for usage. 

OSS allows users to modify the software to meet their unique needs without incurring high costs. Typically, you can set up and implement open-source software without much help. 

Also, for those who do need help, online public software repositories and user communities are sometimes available with useful information and support. Not surprisingly, open-source vendors rarely offer support for their non-licensed codes.  

Is There a Fee for Using Open Source Software? 

Many people use open-source software and free software interchangeably. But it’s important to note that open source and free are not synonyms. While open-source maintenance management software products are generally free, the entire software package isn’t necessarily free.

As explained by How-to Geek, the term “free” refers to user freedoms provided by open-source software. However, different types of licenses are used with open-source software, some of which are only available for a fee. 

Still, as previously mentioned, you don’t have to blow your budget on proprietary work order software to effectively manage your maintenance operations.

Here, we have listed the 7 best Free and Open Source CMMS Software which you can consider for improving your maintenance process, and save time spent on unproductive tasks. But, before we look into the features of each Software in-depth, first let us understand what CMMS Software is, how it works, its benefits, and which features to look for while selecting one for your business.

What is CMMS?

CMMS (Computer Maintenance Management Software) is a system that enables organizations to track the status of the equipment maintenance tasks, and track the location of inventory, replacement parts, and assemblies, generally located in the warehouse or storeroom of the company.

To elaborate further, we have listed down the components of CMMS in detail as given below –

What is CMMS?

Evolution of CMMS

Computerized Maintenance Management Software is commonly used today by the companies worldwide for documenting, standardizing, and verifying maintenance processes. But, earlier, these tasks were done manually using registers, which was quite a time consuming and cumbersome job. However, CMMS was introduced in 1965 and is still evolving, making it easier for businesses to manage their maintenance tasks with each update. So, let’s dive into the important advances of CMMS approximately occurring every 10 years –

CMMS Software Evolution

At present, the market is much more competitive and relying on spreadsheets, and paper records for maintenance tasks can result in costly repairs, reduce the life of assets, and increase the downtime. With the improvements in support services and software functionality, the companies are embracing CMMS solutions to manage their maintenance activities.

The Future of CMMS is IoT (Internet of Things)

IoT and AI are trending topics in almost every business sector these days. Millions of companies are now looking forward to execute IoT in their CMMS so that the machines can monitor themselves and send real-time data to the managers helping them to avoid sudden failures and accidents in their manufacturing units. 

IoT smart devices can monitor usage, helping to plan strategies to save energy costs. Some devices also help the users to turn off HVAC units from their Smartphones. The devices can also put to sleep until any motion activates them.  

The IoT enabled sensors can communicate with your CMMS tools to generate work orders automatically notifying that a repair is needed soon. This helps in reducing downtime and increasing efficiency of the technicians.

How Does a CMMS Work?

A CMMS is used to streamline three tasks – Inspection, Preventive Maintenance, and Repairs. So, let’s have a look at how CMMS can streamline these tasks.

CMMS Process

This systematic approach towards preventive maintenance and inspection helps the company in improving productivity and efficiency. At the same time, it also reduces the chances of breakdowns and sudden accidents. The need for equipment repairs also reduces if maintenance and inspection tasks are done in a timely manner.

CMMS can also help you in quickly finding the maintenance team available to perform the tasks relating to inspection, maintenance, and repairs.

How to Select the Best CMMS?

Now when you know how CMMS replaced the manual registers and excel sheets to streamline the entire maintenance process, it also becomes significant to determine the factors to consider while selecting the best CMMS software. So, here is a list of some features which should be essentially present in the CMMS you select to get the most out of it.

Work Order Management

The CMMS you select should automatically generate work orders depending on the maintenance schedules and repairs when required. It should facilitate users to assign the work orders to the specific maintenance crew and track it till the job is done.


After the need for repairs or maintenance arises, the CMMS system should be able to generate the list of spares required by the technicians and maintenance crew to get that task done successfully. 

Predictive and Preventive Maintenance

The CMMS should facilitate you to predict the future maintenance or schedule preventive maintenance based on the age, make & model, usage, etc.of the equipment. This would help in reducing huge repair costs, and improve the efficiency of the equipment.

Asset Management

There are several types of equipment & machineries at different geographical locations, which you need to monitor and keep track of. An efficient CMMS should help you in accessing the information and managing these assets quickly and accurately.

Inventory Control

Controlling and monitoring inventory in a manufacturing unit is a tedious task, as there are a plethora of spare parts for different makes & models, brands, sizes, etc. kind of variants which need to be managed and made available when required. Your CMMS should make this task seamless.

Insights, Reports, & Analysis

The CMMS you select should provide insights like which equipment are due for maintenance, the cost of repairs, the inventory count or location, and similar data helping you to take quick and informed decisions. It should help you in accessing maintenance related reports easily and analyze critical situations.
