ManageEngine ServiceDesk Plus vs Tessio

ManageEngine ServiceDesk Plus is an IT help desk product with a free plan and a 30-day trial. Its feature set includes SLA management, a knowledge base, approval workflows, an employee portal, single sign-on, and IT asset management. The paid plans separate core help desk use from broader management needs: Standard is $13 a month, billed monthly, for IT help desk work; Professional is $27 a month, billed monthly, and adds asset management; Enterprise is $67 a month, billed monthly, and includes change management and projects alongside the help desk and asset management. The product is available on Android, iOS, Linux, macOS, web, and Windows, with mobile apps listed. That combination gives teams a way to compare the included service and asset capabilities against their plan requirements while accounting for access across desktop and mobile platforms.

Tessio is an IT service desk platform with an integrated AI teammate called Tess. Tess can triage tickets, route them to teams, draft replies, summarize conversations, find similar tickets and search the queue in natural language. The service desk includes ticket queues, intake forms, workflows, SLAs, email-to-ticket, asset and device inventory, dashboards, custom reports and a brandable requester portal. Its knowledge base supports article revisions, and Tess can answer from articles with cited sources. Tess connects to OpenAI and compatible endpoints such as Azure OpenAI, Ollama, LM Studio, vLLM and local gateways. Self-hosting is available through Docker Compose, a single container or Kubernetes; a hosted Cloud edition is also listed. Community is AGPL-licensed and costs nothing, with five admin/agent seats and unlimited requesters.
