iTop vs OTRS

iTop has no write-up on Specifiction yet; its figures are above.

OTRS is help desk and IT service management software for customer service, IT service management, and corporate security. It organizes work as tickets in queues and gives external users a portal for creating and managing requests, using a service catalog, and consulting a knowledge base. Generic Agent jobs, process management, and postmaster filters automate tasks and incoming email handling. A documented REST API accepts incoming calls, while web services require configuration for each system. The SAP Solution Manager Connector supports two-way communication and ticket synchronization, but requires SAP Solution Manager. OTRS is available as managed cloud service or on-premises software, with hybrid deployment listed. It runs on Linux, not Microsoft Windows, and needs a bare-metal server or virtual machine; containerized environments are unsupported. Agent apps for Android and iOS support multiple accounts and two-factor authentication methods. Pricing is on request, there is no free plan, and packages are named Silver, Gold, Titanium, and Platinum.
