A 30-day trial is listed, with no free plan.

openDCIM is a free, web-based application for tracking data center inventory and managing physical infrastructure. Its stated goals include following assets across multiple rooms and managing space, power, and cooling. Custom image maps can show clickable cabinet zones with overlays for power, space, temperature, and weight capacity. The application maps power paths from devices through strips and panels to source feeds, and network links to devices classified as switches. It reports fault tolerance and can simulate the effect of a panel or source-feed outage. Integrations include intelligent power strips and UPS devices from APC, Geist Manufacturing, Liebert, and Server Technologies; OIDs can be updated for other manufacturers. Built on MySQL, it supports report building and exporting data to other applications. Multiple user-rights levels are available, with authentication through Apache or LDAP. It is GPL v3 software for on-premises use. Hosting requirements include Linux, Apache 2.x or higher with SSL, MySQL 5.x or higher, PHP 8.0 or higher, and a web-based client.
