Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Tessio is an open-core IT service management platform for teams that want to run an AI-assisted service desk on their own infrastructure. Its core covers ticket triage and routing, reply drafts, summaries, source-cited knowledge answers, schema-driven intake forms, workflow automation, priority-based SLAs, asset and device inventory, reporting, email-to-ticket through IMAP, and a brandable employee portal. The Community edition is free, self-hosted, AGPL-licensed, and supports unlimited requesters with five administrator or agent seats.

The product's strongest fit is breadth within a self-hosted ITSM model. AI features support both incoming ticket handling and knowledge access, while visual workflows, breach detection, escalation, inventory, dashboards, and custom reports extend Tessio beyond a basic shared inbox. Teams can connect OpenAI, Azure OpenAI, Ollama, LM Studio, or vLLM, giving the platform options for hosted and local model environments. Its documented service channels are email and portal, so organizations needing a wider communications surface should assess that scope carefully.

Deployment choice is a central part of Tessio's structure. Community and Enterprise are self-hosted; Enterprise adds SSO/OIDC and an audit log viewer through a paid per-user subscription. Cloud provides hosted deployment, SSO/OIDC, audit log viewing, managed hosting and upgrades, plus metered AI credits. Tessio suits organizations that value infrastructure control, open-source access, and core ITSM with AI assistance. Teams seeking a broader integration ecosystem or channels beyond email and portal may prefer a more expansive service desk platform.
