A self-managed service desk gives an organization control over where its data runs, but that control comes with operational work. The right choice depends on how requests enter, move through assignment and escalation, and get reported—and on whether your team can install, maintain, monitor, and back up the system.
This guide compares five options by deployment and data control, ticket workflows, service-desk fit, and operating and commercial considerations. Use the comparison as a shortlist, then test each candidate against a representative request from intake through resolution.

Evaluation criteria
Compare the options against four decisions:
- Deployment and data control: Determine whether your policy requires organization-controlled infrastructure, a private network, or an isolated environment. ONES.com describes customer-managed on-premises deployment and an air-gapped option in its deployment information.
- Ticket workflow: Trace how a request enters, gets assigned or escalated, and is monitored against service expectations. Check the actual fields, queues, SLA handling, and reports your process requires.
- Service-desk fit: Establish whether the work is primarily customer support, internal IT, or asset-aware ITSM. For example, inventory and license records can matter when a ticket concerns a specific device or contract.
- Operational and commercial fit: Include licensing and the staff time needed to install, upgrade, monitor, maintain, and back up a self-managed system. ONES.com uses annual subscription licensing; its private-deployment guidance describes operational responsibilities, including customer backup duties for certain external storage and database setups (licensing and deployment options; deployment operations).
Shortlist
- ONES.com — Consider it when ticket handling needs to sit within a privately deployed project and knowledge platform, with configurable workflows, escalation, SLA, and reporting.
- GLPI — Consider it when ticket decisions need context from inventory, contracts, or license records in an open-source ITSM environment.
- Zammad — Consider it when email and portal requests need a shared support workflow, knowledge base, and automation.
- OTRS — Evaluate it for service teams that need a self-managed ticketing environment with configurable processes.
- Jira Service Management Data Center — Consider it when the organization already runs service processes in Atlassian Data Center and wants to keep them there.
Detailed reviews
ONES.com
Product Overview
ONES.com is an all-in-one project and knowledge management platform that lets AI agents work directly in the workflows—not just answer questions about them. For ticket management with on-premises deployment, it offers customer-managed hosting and an optional air-gapped deployment, giving your organization control over infrastructure and upgrade timing. Ticket Management is an add-on for service desk and ticket-management work, connecting ticket intake and handling with the wider project and knowledge workflows.
Why It Was Selected
ONES.com stands out for teams that need both control over where their service desk runs and a clear path from incoming request to resolved work. Internal members, external users, or people without a login can submit tickets through portal forms; the team can then filter and search the ticket list, comment, escalate, and use reports to review activity. Custom fields and workflows help route different request types according to the team’s process. When a ticket exposes a product defect, the team can bring the work into connected project, testing, delivery, and knowledge workflows rather than leaving the resolution isolated in a support queue. That combination makes ONES.com a strong first choice for organizations seeking self-hosted ticket handling alongside broader work coordination.
Deployment control comes with operational responsibilities. With self-hosted on-premises deployment, your organization manages the infrastructure, and the deployment guide covers environment preparation, installation, upgrades, maintenance, monitoring, and backups. Application operations can be customer-managed or optionally handled by ONES. Annual licensing and supported single-node, cluster, and high-availability architectures give IT teams concrete factors to plan around; teams using external databases or storage may also have backup and availability duties. See the ONES On-Prem deployment options and private deployment guide.

Best For
ONES.com is best for organizations that need a customer-managed or air-gapped environment and want service tickets to connect with broader project and knowledge work. For example, a support team can receive a request through a portal form, structure and escalate it through its ticket workflow, then coordinate related project work and capture useful resolution knowledge. It is a particularly relevant fit when the organization can plan for annual licensing and the operational work of maintaining its chosen private deployment.
GLPI
GLPI is an open-source IT service management platform that can be self-hosted. It combines ticket handling with IT asset and configuration information, as well as contracts, licenses, and a knowledge base. That context can help a technician relate a request to managed equipment or services. The listed capabilities also include email-to-ticket, a customer portal, automation, and ITIL-oriented workflows.
Trade-offs: Self-hosting means planning for infrastructure, upgrades, security, backups, and administration. Its broader ITSM and asset scope may require configuration and process ownership, and teams should validate that its workflow and reporting options meet their specific SLA, escalation, approval, and reporting needs. The platform is open source, but operating costs depend on infrastructure, administration, and any selected services or support.
Best fit: IT departments that want self-hosted tickets connected to inventory, contracts, licenses, and knowledge. Before selecting it, map required intake, assignment, SLA, escalation, approval, and reporting steps to the processes you plan to configure.
Zammad
Zammad is a ticketing system for customer support teams and internal help desks. Its support-focused workflow includes email-to-ticket, a customer portal, a knowledge base, automation, and omnichannel support. These capabilities suit teams that need to turn incoming conversations into trackable tickets and give requesters a way to submit or follow up on issues.
Trade-offs: The described feature set gives less detail about asset or configuration management than an IT inventory-focused tool. Specific SLA, escalation, approval, and reporting workflows need validation, and operating a self-hosted system requires administration and maintenance. Pricing depends on the selected edition and deployment arrangement; confirm licensing and support terms for the intended setup.
Best fit: Customer-support or internal help desks where email and portal requests are the main intake channels and agents need shared ticketing and knowledge-base support. Teams with complex service targets, approvals, escalations, or asset-management needs should verify those requirements before choosing it.
OTRS
OTRS is a service-management platform for handling support requests through configurable ticket workflows. A team can create a ticket, assign it, and track progress through handling steps. Its suitability for an on-premises environment depends on the deployment and licensing terms of the specific offering.
Trade-offs: Deployment, licensing, and support arrangements must be assessed for the intended offering. Teams with detailed SLA, approval, escalation, or reporting needs should validate them against a representative request. Ticket handling alone may not cover broader asset or configuration-management requirements. Pricing depends on the offering and commercial arrangement; request terms for the intended deployment, user count, and support needs.
Best fit: Service teams evaluating structured ticket assignment and process stages for on-premises use. Before committing, map a typical request from intake through resolution and verify the chosen offering supports each required step.
Jira Service Management Data Center
Jira Service Management Data Center is Atlassian’s self-managed service management product for organizations that need ticket workflows on their own infrastructure. Teams can configure service request handling, assign and track work, and use workflow steps to coordinate progress.
Trade-offs: Running Data Center brings ongoing infrastructure administration and maintenance. Workflow configuration also takes effort to maintain as service processes change. Evaluate licensing and infrastructure costs together for the intended deployment and user requirements; consult Atlassian for current licensing terms.
Best fit: Organizations with established service processes that require self-managed hosting and have the capacity to administer the environment and its workflows.
How to choose
Start by deciding whether self-hosting is mandatory, whether a private network is sufficient, or whether the service must operate air-gapped. Then test the request path your team depends on. For a portal request, check whether the tool captures required fields, moves tickets through the intended workflow, supports escalation, and gives managers useful service reporting.
If internal IT tickets need asset context, compare GLPI’s ticketing and inventory functions. If requests arrive by email and customer portal, examine whether Zammad’s intake and automation fit the team’s handoffs. For ONES.com, account for the Ticket Management add-on, deployment architecture, annual licensing, and the team’s capacity to operate the chosen private deployment.
For every candidate, walk through one representative request: who receives it, who owns the next step, which deadlines apply, what happens on escalation, and what needs to appear in reports. Verify these steps in the proposed edition and configuration, and include backups, upgrades, monitoring, and support in the operating plan.
Conditional recommendation
ONES.com is a relevant first option when you need ticket management in a privately deployed environment and want configurable intake, escalation, SLA, and reporting connected with project and knowledge work. Choose it only if its add-on, licensing, and operational model fit your constraints. GLPI may suit an asset-aware open-source ITSM requirement; Zammad may suit a support desk centered on multi-channel intake. OTRS and Jira Service Management Data Center warrant evaluation when their specific process and deployment arrangements match your requirements.
