openMAINT

openMAINT is an open-source CMMS for managing buildings, sites, plants, technical devices, mobile assets, and their related logistics, economic, and maintenance activities. Facility Management covers preventive and corrective maintenance for sites and registered assets. The inventory module records real estate, plants, and components, including their status and technical characteristics. Assets can be georeferenced and displayed on territorial maps, 2D GIS layouts built with DWG imports, and 3D BIM models synchronized through IFC files. Users can configure data schemes, object types, attributes, workflows, reports, filters, and views. Integrations include web services, external-system connectors, CSV import and export, and CMIS-compatible document management. The web-based system runs on a web server and is accessed through a browser; the maker lists Linux, OSX, and Windows. Stated technical requirements include PostgreSQL 17.x, Apache Tomcat 10, and Java 17, with PostGIS and Docker optional. The software is available under the GNU Affero GPL. The free Self-Service plan excludes the mobile app and Self-Service Portal. The mobile app supports Android 5.1 or later and iOS 11 or later, but use requires a maintenance service subscription.

openMAINT combines maintenance workflows with asset inventory, GIS, BIM, and configuration options. The free plan excludes mobile access and the Self-Service Portal; the annual subscription's price depends on instance complexity and SLA.

openMAINT suits organizations managing facilities, assets, and maintenance, including public administrations, healthcare organizations, schools, transport operators, and industrial companies. It is aimed at teams able to run a web server and meet its stated technical requirements.

openMAINT is a web-based CMMS for organizations responsible for buildings, equipment, and the work that keeps them running. It suits teams that need a configurable system spanning asset records, maintenance, and spatial building information. Its free plan covers a broad operational scope, while mobile access and the self-service portal require an annual subscription.

Overview

openMAINT combines property and facility management with preventive and corrective maintenance for sites and registered assets. Its inventory records real estate, plants, and components, including their status and technical characteristics. Spare-parts inventory, logistics, economic management, and energy and environment functions give it a wider remit than a work-order tracker.

The AGPL license permits use, distribution, and editing. In return, self-hosting calls for an organization able to run a web server and manage a stack that includes PostgreSQL 17.x, Apache Tomcat 10, and Java 17. PostGIS and Docker are optional. That deployment requirement makes openMAINT a better fit for teams with technical capacity or a support plan than for organizations seeking a turnkey cloud service.

Key features

Inventory and spatial context

Teams can georeference assets on territorial maps, use 2D GIS layouts built from DWG imports, and synchronize 3D BIM models through IFC files. These views can connect maintenance records to the physical setting of a building or site, which is useful when location and structure matter to asset management. Organizations that only need basic equipment lists may not benefit enough from this added scope to justify configuring it.

Configurable operations and connections

Administrators can model data schemes, define object types and attributes, customize workflows and reports, and create filters and views. Web services, external-system connectors, CSV import and export, and CMIS-compatible document management provide routes to exchange data and documents. This flexibility can accommodate varied organizations, but it also puts more responsibility on the team to shape the system around its processes.

Maintenance and mobile access

Preventive and corrective maintenance cover sites and registered assets, with spare-parts inventory supporting the work. A native CMDBuild mobile app is available for Android 5.1 or higher and iOS 11 or higher, but using it requires a maintenance service subscription. The free plan therefore suits teams able to work through the browser; field staff who need mobile access should budget for the paid option.

Pricing

Self-Service — free

The free plan includes space and asset inventory, facility management, logistics, economic management, energy and environment, and GIS and BIM. Facility management excludes the Self-Service Portal, and the plan has no mobile app or portal. It is a substantial starting point for organizations that can self-host and do not need those access channels, but the missing mobile app is a meaningful constraint for maintenance teams working away from a desk.

Annual Subscription — custom pricing

The annual subscription covers one production instance for 12 months and is renewable yearly without automatic renewal. Price depends on instance complexity and SLA; complexity takes account of users, buildings or units, assets, workflows, connectors, clustering, and multitenancy. It includes a certified appliance, help desk, bug fixes with a guaranteed SLA, platform updates, mobile app, and Self-Service Portal. This is the better fit for organizations that need support commitments or mobile and portal access, though the instance-based pricing means teams should assess scope and SLA when budgeting.

Platforms

openMAINT is web-based and accessed through a browser on a web server; the maker says it runs on Linux, OSX, and Windows. The software is also associated with Android, iOS, API, and self-hosted platforms. Mobile app support is native for Android and iOS, subject to the stated OS versions and maintenance subscription. The AGPL license allows organizations to use, distribute, and edit the software.

Who it's for

Public administrations, banks, healthcare organizations, schools, service companies, transport operators, industrial companies, and other businesses are among the intended users. The strongest fit is an organization managing many kinds of property and technical assets that can benefit from configurable workflows and GIS or BIM context. A small team looking for a simple, hosted maintenance app may find the technical deployment and configuration burden disproportionate.

Pros and cons

• Broad operational coverage: Facility maintenance, asset and space inventory, spare parts, logistics, economics, and energy and environment functions sit in one system.
• Useful spatial tools: Territorial maps, DWG-based 2D layouts, and IFC-synchronized 3D BIM models connect assets with their site and building context.
• Adaptable data and workflows: Teams can define object types, attributes, workflows, reports, filters, and views to match varied operations.
• Meaningful free tier: The free plan includes GIS and BIM alongside inventory and facility management, but omits mobile access and the Self-Service Portal.
• Technical ownership required: Self-hosting depends on a web server and a substantial software stack, so organizations need capacity to operate it.
• Mobile access carries a subscription requirement: Field teams cannot use the native app under the free plan.

Verdict

openMAINT is a strong choice for organizations managing complex facilities and technical assets that want configurable maintenance, inventory, and GIS or BIM capabilities under an open-source license. Its free plan provides substantial functionality, but the web-server deployment requirement and the subscription gate on mobile access and the Self-Service Portal are central trade-offs. Choose it when your team can operate the system and values its breadth; look elsewhere if you need a turnkey service or free mobile access.
