ManageEngine OpUtils vs RackTables

ManageEngine OpUtils is a network management toolset for monitoring, diagnosing, and troubleshooting IP resources and network devices. It manages IP address space, maps devices to switch ports, and combines DNS, DHCP, and IP address management, including Microsoft DNS and DHCP. More than 30 network utilities cover diagnostics, SNMP, Cisco, address monitoring, and connectivity. Security controls can detect rogue devices, alert on IP conflicts and ARP spoofing, and apply DHCP MAC-based filtering. Role-based access control and two-factor authentication are supported.

OpUtils integrates with Microsoft DHCP and DNS, Cisco Meraki controllers, and ManageEngine products including OpManager and NetFlow Analyzer; APIs can connect it with third-party IT management and service desk software. The downloadable product is offered for 64-bit Windows and Linux and is accessible through a browser. Mobile apps for iOS and Android monitor network addresses and ports. The free edition costs nothing and supports one Class C subnet and one switch. The Professional plan is priced on request, and Management is priced on request. A 30-day trial is available.

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.
