The record

Product: Tessio is an IT service desk platform with an AI teammate called Tess built in.
AI features: Tess can triage tickets, route them to teams, draft replies, summarize, find similar tickets, and search the queue in natural language.
Knowledge base: The knowledge base supports article revisions, and Tess can answer from its content with cited sources.
Service desk features: The core toolkit includes ticket queues, intake forms, workflows, SLAs, email-to-ticket, asset and device inventory, dashboards, custom reports, and a brandable requester portal.
LLM integrations: Tess can connect to OpenAI and OpenAI-compatible endpoints including Azure OpenAI, Ollama, LM Studio, vLLM, and local gateways.
Privacy: The maker says self-hosted deployments send data only to the LLM endpoint chosen by the customer, and Tessio is not configured for telemetry, analytics, or phone-home behavior.
AI controls: The maker says personally identifiable information is redacted at the model boundary, and AI stays off until an LLM key is provided.
Enterprise security: SSO/OIDC and an audit log viewer are listed for Enterprise and Cloud; SCIM provisioning, custom roles/advanced RBAC, and advanced SLA are marked for a future release.
Deployment: Self-hosting options include Docker Compose, a single-container setup, and Kubernetes; the maker also lists a hosted Cloud edition.
Licensing: The Community edition is self-hosted and AGPL-licensed; the repository says the enterprise directory is commercial.
Intended users: The maker describes Tessio as an open alternative to ServiceNow, Zendesk, and Freshservice for teams that want their tickets and data on their own infrastructure.
Notable limit: Community includes five admin/agent seats, while requesters are unlimited and free across editions.
Price from: Free
