What it is

Atlas CMMS is a self-hosted computerized maintenance management system written in TypeScript and licensed under AGPL-3.0. It provides a web application and a mobile application for managing maintenance work, equipment, inventory, locations, and service requests. The project lives in the open-source business software and ERP operations ecosystem, and it is deployed with Docker.

The concrete problem it solves is coordinating enterprise maintenance activities across assets, teams, requests, approvals, and costs. Facilities, manufacturing, healthcare, hospitality, public sector, education, and utility organizations need to create work orders, assign technicians or service providers, log time, track equipment downtime, manage inventory, and review maintenance costs. Atlas CMMS provides a single system for these activities, with work order tracking, equipment records, inventory alerts, purchase approvals, reports, and role-based workflows.

Key capabilities

• Work orders can be created, assigned, tracked, prioritized, and logged with time and history.
• Automated work orders can be generated with triggers, and workflows can be defined with automation logic.
• Equipment records can track downtime and maintenance costs, while inventory management supports stock alerts.
• Purchase orders and approvals can be automated, linking maintenance needs to procurement.
• Reports and analytics cover work order compliance, cost analysis, equipment reliability, cost trends, and labor tracking.
• User and workflow management supports teams, service providers, customizable roles, and permissions.
• Locations can be managed with Google Maps integration, and service requests can be created and tracked.

Who uses it and how

• Facilities managers use it to track building, property, and real estate maintenance requests and assign work to teams or external providers.
• Manufacturing and production teams use it to maintain machinery, record downtime, manage inventory, and analyze maintenance costs.
• Healthcare facilities use it to track medical equipment maintenance and service history.
• Hospitality, public sector, educational institutions, and utility companies use it to manage distributed locations and infrastructure maintenance.
• IT managers or developers deploy it to centralize maintenance operations while keeping data on self-managed infrastructure.

Getting started

The typical deployment method is Docker: download the provided docker-compose.yml, nginx.conf, and .env.example file, rename the environment file, set required variables, and run docker-compose up -d. The application is then accessed through a browser at the configured public URL or localhost port 3000.

When to use it — and when not to

Atlas CMMS is a good fit for organizations that need a free, self-hosted maintenance system and can operate the required dependencies, including PostgreSQL, MinIO, and a JWT secret. It is less suitable for teams that want a fully managed service or that cannot maintain database, object storage, and optional SMTP or SendGrid configuration. The repository is two years old and lists 34 open issues, so adopters should evaluate its production readiness and customization needs before committing.
