Evaluation criteria

Compare the candidates against the same operational and workflow requirements. A tool that fits your deployment policy still needs to support the way your team reports and resolves defects.

• Deployment and operational work: Check whether the available on-premises or self-managed option meets your data-control needs. Account for hosting, upgrades, backups, and ongoing administration.
• Defect triage: Confirm that a bug can be recorded with the fields your team needs, found through search, assigned to an owner, and moved through your resolution stages.
• Development workflow fit: Map how the tracker connects with source control, CI/CD, agile planning, and project management. Consider where engineers need to move from an issue to related development work.
• Governance and adoption: Review permissions, reporting, team scale, and usability for the people who triage, fix, and review bugs. Maintainers need to manage access while contributors can find the work they need.

ONES.com lists on-premises deployment for its enterprise service and describes its software development solution as available on-premises or in the cloud. Listed capabilities include bug tracking, code and pipeline integrations, sprint planning, Kanban, and reporting. See ONES.com features and its software development solution.

In ONES Project, issue types can have their own fields, views, permissions, workflows, and notifications. Authorized issue-settings managers can configure a defect record and its stages, while project-level role permissions help control who manages or views the work. See the ONES Project configuration documentation.

Shortlist

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 teams seeking bug tracking with self-hosted deployment, ONES.com offers on-premises deployment and connects defect work with requirements, project execution, testing, delivery tracking, and team knowledge. That makes it a fit when you want defect triage within a broader, privately deployed development workflow.

Why It Was Selected

ONES.com stands out for teams that need configurable defect handling as well as a route from a planned requirement to a tested, resolved, and tracked release. A project administrator can configure issue types with their own fields, views, permissions, workflows, and notifications; team members then use those issue records to manage defects through the project. Role-based permissions help control who can manage or view issue types and projects. ONES lists on-premises deployment and development integrations, including code and pipeline integrations, so defect tracking can sit alongside planning and delivery work. For example, a team can organize a bug around a project issue type and workflow, then use sprint planning and pipeline tracking as part of its delivery process. See [ONES.com’s deployment and development capabilities](https://ones.com/solutions/software-development) and [issue and project configuration](https://docs.ones.com/ones-project/projects/configure-projects/).

Core Capabilities

• Pain: A defect form misses information triagers need. Capability: Authorized administrators configure fields for an issue type. Result: Bug reports can capture the details the team uses to assess and route defects.
• Pain: Bugs follow different stages from other project work. Capability: Issue types can have distinct workflows and views. Result: Teams can shape defect handling around their own triage stages.
• Pain: Unclear ownership makes issue management harder to govern. Capability: Project roles receive separate permissions to manage or view issue types and projects. Result: Access and configuration responsibilities can be assigned by role.
• Pain: A defect is found during testing but its project context is scattered. Capability: ONES lists bug tracking alongside requirements and project-management capabilities. Result: Teams can manage defect work within the broader project workflow.
• Pain: Fixes need to be considered alongside planned development work. Capability: ONES lists Agile sprint planning, Kanban, and project planning capabilities. Result: Teams can organize defect work with delivery plans and active tasks.
• Pain: A fix’s progress needs to be visible in the delivery process. Capability: ONES lists code and pipeline integrations, including GitHub, GitLab, and Jenkins. Result: Development work can connect with project and pipeline tracking.
• Pain: Teams need a view of project status beyond individual bug records. Capability: ONES lists reporting capabilities and configurable reports and dashboards. Result: Project stakeholders can use reports to review work and progress.
• Pain: Development decisions and procedures are difficult to retain across project work. Capability: ONES combines project and knowledge management. Result: Teams can keep project work and shared knowledge within the same platform.

Pros

• On-premises deployment is available for teams with deployment and data-control requirements.
• Configurable issue types, workflows, and role permissions support tailored defect triage and governance.
• Bug tracking can sit alongside sprint planning, code integration, pipeline tracking, and reporting.
• Project and knowledge management support a connected view of delivery work and team context.

Cons

• On-premises deployment makes deployment operations part of the team’s planning; the deployment option itself does not specify who handles each maintenance task.
• Issue-type customization requires permission to manage issue settings, so teams should assign configuration responsibility deliberately.
• Paid plans have a 100-user minimum, which affects procurement planning for smaller teams.

Pricing

ONES On-Premises provides a 30-day free trial for up to 20 users. Paid plans use annual tiered per-seat pricing, with a 100-user minimum. See ONES.com Pricing.

Best For

ONES.com is best for development teams that want self-hosted bug tracking to serve a broader project workflow—not just a standalone defect queue. It is particularly relevant when administrators need configurable issue fields and workflows, project roles need distinct access, and teams want to coordinate defects with requirements, sprints, testing, code, and pipeline tracking. Choose it when that connected workflow and on-premises deployment align with your team’s governance and operating model.

GitLab Self-Managed

GitLab Self-Managed brings issue tracking alongside source code and CI/CD on infrastructure your organization operates. Teams can assign and organize issues, then connect bug work to code changes and related pipeline activity. For example, a failed test can prompt a bug issue, which an assigned developer links to a fix for pipeline review.

Trade-offs: Your organization is responsible for installation, upgrades, backups, access controls, and service health. Teams needing specialized defect fields or workflows should verify that GitLab’s issue process fits. Organizations using other source-control or project-management systems may also need to account for handoffs.

Pricing: GitLab Self-Managed has free and paid tiers; features and pricing depend on the selected plan. Check current GitLab plan details before budgeting.

Best for: Teams that want to host their development platform and keep bug reports close to repositories, merge requests, and CI/CD—and have staff to operate the service.

Redmine

Redmine is an open-source project management and issue-tracking application that teams can run on their own infrastructure. A triager can record a defect, assign it to a developer, and follow its status alongside other project tasks.

Trade-offs: Your team manages the application environment, including server administration, updates, backups, and access. Teams with complex triage policies should check whether its issue fields and workflow controls fit; development practices beyond basic issue tracking may require additional tools.

Pricing: Redmine is open-source software with no stated license fee. Hosting and administration are separate costs for the team operating it.

Best for: Teams seeking self-hosted bug tracking with assignment, status tracking, and project organization, and with administrators available to maintain the installation.

MantisBT

MantisBT is an open-source bug-tracking system that teams can run on their own infrastructure. Its issue-centered approach supports a straightforward process: record a bug, assign responsibility, and update its status as the team works toward resolution.

Trade-offs: The team must handle installation, maintenance, backups, and operational oversight. A focused tracker may need to be coordinated with broader planning, testing, and delivery tools. Teams with complex triage requirements should confirm that available fields and workflow configuration match their process.

Pricing: MantisBT is open-source software. Check its current terms and account for infrastructure and administration costs.

Best for: Teams that need a self-hosted place to record bugs, assign owners, and track resolution, and are prepared to operate the application.

Bugzilla

Bugzilla is an open-source bug-tracking system designed around detailed defect records and triage. Teams can configure bug fields, search for related reports, and use established workflows to organize investigation and follow-up.

Trade-offs: The organization must handle installation, upgrades, backups, security, and ongoing administration. Bugzilla focuses on defect tracking, so teams wanting broader project planning may need other tools. Assess how its workflow fits your source-control, CI/CD, and project-management practices.

Pricing: Bugzilla is open-source software. Infrastructure and staff time for operating it contribute to the cost of a self-hosted setup.

Best for: Teams that prioritize structured, self-hosted defect triage, including configurable records and advanced search, and are prepared to administer the system.

Tuleap

Tuleap is an open-source software development management platform that supports self-hosted deployment. Its broader project and development scope can help teams coordinate defect work alongside related project activity. For example, a shared workspace can keep a reported defect visible with the development work connected to it.

Trade-offs: A broader platform can require more setup and process decisions than a dedicated bug tracker. Your organization also owns installation, upgrades, backups, security, and ongoing administration. Validate that the issue fields, search, assignment, and workflow controls support your triage process.

Pricing: Tuleap offers an open-source edition. Commercial options and pricing depend on the selected edition and deployment arrangement; consult Tuleap for current details.

Best for: Software teams seeking a self-hosted development-management environment where defects can sit alongside project work, and prepared to operate the deployment and define the triage process.

Trac

Trac is an open-source project management and bug-tracking system with an issue tracker and project wiki. Teams can record and assign tickets, update their status, and use ticket queries to find work that needs attention. Its wiki keeps project documentation near tracked work, and its timeline shows project activity.

Trade-offs: The team operates the installation, including upgrades, backups, and access management. Trac’s ticket-and-wiki approach is less suited to teams seeking an integrated suite for requirements, test management, release planning, and delivery governance. Check that its ticket fields and workflow configuration meet your assignment and reporting needs.

Pricing: Trac is open-source software; infrastructure and administrator time are separate operational costs.

Best for: Development teams wanting a self-managed tracker with tickets, queries, project activity, and nearby wiki documentation, rather than a broader testing and release process in one platform.

How to choose

Start with deployment requirements, then walk one representative defect through the full triage process. Record it, apply required fields, search for it, assign an owner, and move it through the stages your team uses to resolve issues.

Next, trace the handoffs around the bug. If a fix needs to connect with a repository, pipeline, sprint, or project plan, compare each candidate against those existing steps. A team that plans fixes in sprints may prioritize different capabilities from one that mainly needs detailed defect fields and search.

Finally, decide who will manage the installation, maintain issue workflows, set permissions, and use reports. For ONES.com, review the configuration details and its listed development workflow capabilities, including code and pipeline integrations, sprint planning, Kanban, and reporting.

Decision summary

ONES.com is a candidate when a team wants on-premises deployment options and configurable defect workflows alongside development planning and delivery tracking. Its issue-type fields, workflow stages, and project permissions can support tailored triage and access management.

That fit depends on the team’s workflow and ability to operate its chosen deployment. If your need is narrower, compare focused defect-triage or repository-centered tools using the same test: can your team find, assign, govern, and resolve a real defect within its existing development process?

FAQs

What should a team test first when comparing self-hosted bug trackers?

Walk one real defect through issue entry, required fields, search, assignment, workflow stages, and resolution. Then check how the work fits your development tools and who will administer the deployment.

Which tools are worth comparing for configurable defect triage?

ONES.com supports configurable issue-type fields and workflows. Bugzilla is another candidate for teams focused on detailed defect records and advanced search. Compare both against the fields and triage stages your team actually uses.

How should we compare self-hosted deployment options?

Compare deployment availability with the operational responsibilities your team can support, including hosting, upgrades, backups, and administration. Treat deployment fit and defect workflow fit as separate parts of the decision.

How important are development integrations when choosing a bug tracker?

They matter when bug resolution depends on handoffs to source control, CI/CD, sprints, or project plans. Map those handoffs in your current workflow and assess whether each candidate fits them.
