Device42 vs RackTables

Device42 provides agentless discovery, asset management, and dependency mapping for data center, cloud, and hybrid IT environments. Its scope includes CMDB, DCIM, ITAM, IPAM, password management, and application dependency mapping, in a self-hosted deployment. It can discover network devices through SNMP and cloud resources across AWS, Azure, Google Cloud, Oracle Cloud, and OpenStack.

For data centers, its visual models cover buildings, rooms, racks, cabling, and patch panels, with power and temperature heat maps. Core includes discovery, inventory and asset management, integrations, REST APIs and webhooks, warranty and SSL certificate management, cable and password management, and IPAM. Device42 also tracks software licenses, contracts, and barcodes, and lists more than 30 integrations. Licenses count devices with IP addresses; non-IP assets do not count, and user seats are unlimited. If the device limit is exceeded, the software keeps running but stops collecting additional information until the license is increased. Pricing is available on request, and a free trial is offered.

RackTables is a free, web-based datacenter asset management system for documenting equipment, network addresses, rack space, and network configuration. It tracks devices, racks, and enclosures, and lets users mount devices in racks. Racks can be organized into rows so teams can check available capacity and mark unusable rack units. For network records, RackTables manages IP addresses and networks, documents NAT rules, and stores load-balancing policies and configurations. Users can maintain device ports and the links between them. Flexible tags and filtering rules help organize and retrieve hardware, while files can be attached to system objects. Accounts and permissions control which actions users may perform. RackTables is an on-premises PHP application accessed through a browser with an internet connection. The project identifies version 0.22.0 as its latest stable release. It provides a mailing list and bug tracker; issue reports are public by default but can be made private.
