License & Deployment Mix: 30 tools – 5 OSS, 1 source-available, mostly SaaS. (OSS and SaaS counts can overlap when an open-source tool also offers a vendor-hosted edition. openMAINT, Atlas CMMS, Liberu, Odoo Maintenance, and ERPNext are OSI-approved open-source tools; CalemEAM’s Community Edition is source-available under a custom license. Odoo and ERPNext maintenance are modules of larger open-source ERPs rather than standalone CMMS.)

What Is a CMMS?

A Computerized Maintenance Management System (CMMS) is software that centralizes maintenance information – work orders, preventive maintenance schedules, asset histories, spare parts inventory, and labor tracking – into a single platform. CMMS helps organizations plan, track, and optimize maintenance activities across facilities, equipment, and infrastructure.

Unlike spreadsheets or paper-based systems, a CMMS automates scheduling of preventive maintenance, tracks work order lifecycles from request to completion, manages spare parts inventory, and provides KPI dashboards for maintenance performance.

Comparison

SSO / OIDC Comparison

OIDC is the preferred SSO protocol. The Authentik Notes column records compatibility with the Authentik identity provider.

Best SSO support: IBM Maximo, SAP, Infor, Nuvolo (via ServiceNow), and IFS Ultimo offer OIDC + SAML plus SCIM. Fiix, Fracttal, IBM TRIRIGA, Planon, and the Odoo/ERPNext ERP modules support OIDC (ERPNext has a documented Authentik guide). Most cloud CMMS tools support SAML at minimum. Coast and Liberu lack SSO entirely; MicroMain and eWorkOrders advertise SSO but do not publicly document the protocol.

Deployment Comparison

Core Features Comparison

Odoo and ERPNext are ERP modules: parts inventory comes from their Inventory/Stock apps, not the maintenance module itself.

IBM TRIRIGA, Planon, and Nuvolo are IWMS platforms: asset management is real-estate/portfolio-centric, and TRIRIGA defers equipment parts/work to Maximo.

Corrigo and ServiceChannel are contractor-network FM platforms: their strength is vendor dispatch, so MRO parts inventory is not a core feature.

Advanced Features Comparison

* = Fiix Foresight AI for failure prediction

* = Maximo Application Suite includes Monitor and Health for IoT + predictive maintenance

* = Fracttal AI-powered failure prediction

* = Atlas multi-site, purchase orders, and full API access are gated behind a commercial LICENSE_KEY

* = IFS Ultimo bundles a deep EHS/safety module (LOTO, work permits, incidents) inside the EAM

Brightly predictive/IoT is the paid Smart Assets add-on; Facilio leads on native IoT/BMS integration with fault detection and energy analytics.

API & Integration Comparison

* = Infor ION middleware for event-driven integrations

Best API support: IBM Maximo and Fiix offer the most comprehensive REST APIs. UpKeep, Limble, MaintainX, Fracttal, ServiceChannel, Facilio, IFS Ultimo, and Planon provide modern APIs with OpenAPI specs (ServiceChannel and Facilio publish public developer portals; IFS Ultimo ships OAS 3.0). ERPNext and Odoo expose full ERP APIs (Frappe REST and XML-RPC/JSON-RPC). IBM TRIRIGA integrates via OSLC. Brightly and Corrigo have real but partner-gated APIs; Coast, Liberu, and MicroMain have little or no public API.

Monitoring Integration

Monitoring integration via the monitoring stack for CMMS tools deployed in managed environments.

Most CMMS tools are SaaS-only, limiting monitoring to HTTP endpoint checks and API-based health queries. On-premise / self-hostable deployments (openMAINT, Atlas CMMS, Odoo, ERPNext, Maximo, Infor, IBM TRIRIGA, Planon, Maintenance Connection, Mpulse) allow full monitoring stack monitoring of the underlying database and application server. Planon and IBM TRIRIGA also offer vendor-managed SaaS, where monitoring falls back to HTTP checks.
