In their own words
ColdAisle
ColdAisle is free, MIT-licensed, on-premise software for managing data center infrastructure. It runs on Windows using IIS, PHP, and SQL Server, and the marketing site does not host customer inventory. Its floor planner supports 2D layouts and interactive 3D views with cabinets, row PDUs, and raceways. Power tools cover A/B zones, panels, single-, dual-, and three-phase PDUs, outlet inventory, history charts, and overload alerts. Cooling features include CRAC and CRAH equipment, environmental sensors, and 3D airflow visualization. Device monitoring supports SNMPv2c and SNMPv3, MIB uploads, discovery, OID templates, and scheduled polling; SNMP secrets are encrypted at rest with the application key. Authentication options include local accounts, LDAPS with Active Directory group mapping, and Microsoft Entra ID OIDC single sign-on. ColdAisle can import openDCIM data through a live API or offline JSON dumps, with a preview before migration. Its IPAM feature does not provide IPv6, DNS, or a DHCP server.
openDCIM
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.
