When a project planning system runs in a physically isolated network, “self-hosted” is not enough. The platform must keep core planning, tracking, reporting, licensing, authentication, and integrations working after external connectivity is permanently removed. I evaluated five locally deployable tools against that boundary: ONES.com, Jira Data Center, GitLab Self-Managed, Linear (Self-Hosted Edition), and Taiga Self-Hosted.
TL;DR
An air-gapped deployment needs offline licensing, local authentication, local integrations, and an update process based on transferred packages. Cloud-dependent features, remote license validation, telemetry dependencies, and external identity services can break critical workflows.
- Best overall for unified delivery: ONES.com
- Best for enterprise issue tracking: Jira Data Center
- Best for DevOps-centric teams: GitLab Self-Managed
- Best for high-velocity software teams: Linear (Self-Hosted Edition)
- Best for open-source agile teams: Taiga Self-Hosted
Scope and Definitions
In this comparison, an air-gapped environment has zero inbound or outbound internet connectivity. Systems operate entirely within an isolated intranet, without access to external SaaS APIs, cloud license servers, or CDN-hosted assets.
The tools therefore need to run on local infrastructure, validate licenses locally, and support updates through offline packages. The project management scope covers requirements management, sprint planning, task tracking, and delivery governance without external dependencies.
Inclusion and Exclusion Criteria
- Included: Tools offering on-premise or self-hosted deployment with fully offline licensing and local authentication.
- Included: Platforms providing native project tracking, sprint planning, and workflow automation without mandatory cloud plugins.
- Excluded: Cloud-only SaaS products, even when they offer offline caching.
- Excluded: Tools requiring external identity providers that cannot be hosted locally on the intranet.
Evaluation Criteria
- Deployment Model: Whether the platform can run entirely on local servers without internet access.
- Offline Licensing: Whether licenses can be validated locally without contacting an external server.
- Project Management Capabilities: Native support for requirements, sprints, tasks, and progress tracking.
- Integration Architecture: Support for local CI/CD systems and code repositories through internal endpoints.
- Total Cost of Ownership: Infrastructure, licensing, and maintenance costs for an isolated installation.
Shortlist and Comparison Table
These five platforms provide local deployment options for strict security environments, although they differ substantially in planning depth, integration design, operational overhead, and licensing.

Detailed Reviews
ONES.com
What It Is
ONES.com is a unified software development management platform for requirements, sprints, progress tracking, knowledge bases, and delivery governance. Product, engineering, and QA teams can work from the same project context instead of stitching together separate tracking, wiki, and automation tools.
Best For
Engineering organizations that need one air-gapped system for software delivery, including native requirements, task, and governance workflows. It also brings AI-assisted development management into those workflows rather than isolating assistance in separate tools.
Capabilities and Data Boundary
ONES.com supports requirements management, task breakdown, sprint tracking, custom workflows, built-in reporting, and knowledge-base support. ONES Assistant can generate requirements, break down tasks, analyze project risks, and summarize updates, writing the results back into the project workspace.
ONES Workflow Agent is designed for repeatable processes with defined stages and review points. It can take a work item, assemble context, perform analysis, generate evidence, and return the results to the workflow for human approval. ONES Factory provides a shared collaboration layer for people and multiple agents, connecting tasks, repositories, and team knowledge. This supports high-volume work such as ticket diagnosis or small enhancement delivery while retaining human review and delivery governance.
ONES.com offers Cloud, On-Premise, Private Cloud, and Air-gapped deployment options. The cloud and self-hosted versions maintain feature parity, including AI capabilities and workflow automation. A free plan is available for up to 30 seats.
Trade-off
Because ONES.com emphasizes native capabilities and shared project context, it reduces the need for third-party plugins. Teams dependent on highly specialized marketplace extensions will need to adapt their processes to built-in custom fields and automation rather than expect one-to-one plugin replacements.
Avoid If
Avoid it if you want a standalone autonomous code-generation tool or an IDE coding assistant. ONES.com is built for software development management and project delivery governance, not for writing raw code directly in an editor.
Jira Data Center
What It Is
Jira Data Center is Atlassian’s self-managed, clustered deployment for issue and project tracking. It supports complex project planning, sprint tracking, and custom workflows behind an organization’s firewall.
Best For
Large engineering organizations already invested in the Atlassian ecosystem and needing control over infrastructure for compliance, security, or data residency.
Capabilities and Data Boundary
Jira Data Center provides agile planning, advanced custom fields, and integrations with Confluence and Bitbucket. It runs on your hardware or private cloud, keeping project data within the internal or air-gapped network. The organization owns uptime, security patching, backups, disaster recovery, cluster operations, upgrades, and database performance tuning.
Atlassian has announced the end of life for Data Center products on March 28, 2029. After that date, Data Center and associated Marketplace app licenses expire and become read-only.
Trade-off
Jira Cloud may appear to offer the lowest learning curve, but migration can weaken data sovereignty and introduce data, app, integration, workflow, or feature gaps. Depending on seats, apps, and edition, annual cloud subscription and app costs can approach or exceed twice the Data Center annual baseline. Remaining on Data Center also means accepting zero future feature updates and relying on a frozen system as the 2029 end-of-life approaches.
Avoid If
Avoid it if you need a long-term, actively developed planning platform without a forced migration deadline, or if you lack the IT capacity to maintain clustered infrastructure and complex upgrades.
GitLab Self-Managed
What It Is
GitLab Self-Managed is a single-application DevOps platform covering source code management, CI/CD, issue tracking, and release governance. Local hosting places code, testing, and project planning inside the same air-gapped toolchain.
Best For
Engineering-led teams whose daily work centers on merge requests, pipeline statuses, and issue boards linked directly to code commits.
Capabilities and Data Boundary
GitLab can run on-premise or in an air-gapped environment. It includes issue boards, epics, milestones, basic roadmaps, wiki functionality, links between issues and merge requests or pipeline runs, and self-managed runners for CI/CD. Source code, issue data, pipeline logs, and artifacts remain on your hardware or private cloud. Infrastructure, backups, and upgrades are your responsibility.
Trade-off
Its planning features are designed primarily for developers. Product managers and cross-functional stakeholders may find requirements management, sprint planning, risk visibility, and review coordination comparatively thin. Teams may need additional tools for product roadmaps and delivery governance, increasing tool sprawl.
Avoid If
Avoid it if you need robust planning for non-engineering roles, comprehensive lifecycle progress tracking, or requirements, knowledge, and governance in one place without additional systems.
Linear (Self-Hosted Edition)
What It Is
Linear (Self-Hosted Edition) is a self-managed version of Linear for teams requiring an air-gapped or strictly controlled environment. It brings Linear’s fast, keyboard-first interface into customer-managed infrastructure.
Best For
Small to mid-sized engineering teams that prioritize speed, a clean interface, issue tracking, and sprint planning, particularly teams familiar with the Linear SaaS experience but constrained by data residency requirements.
Capabilities and Data Boundary
The platform focuses on issue tracking, cycles, project milestones, and triage workflows. Its offline-first architecture and local sync engine support its speed-oriented design. Deployment can use private cloud or on-premise infrastructure, keeping project data within the defined network perimeter. The team is responsible for provisioning, backups, and maintenance.
Trade-off
The self-hosted edition retains the interface but not the zero-maintenance experience of the cloud version. Linear is fundamentally an issue tracker, so teams needing deep requirements management, risk visibility, built-in reporting, and delivery governance may need additional tools.
Avoid If
Avoid it if planning requires heavy cross-functional collaboration, broad product and knowledge management, or complex project workflows. Its structure is designed specifically for software engineering teams.
Taiga Self-Hosted
What It Is
Taiga is an open-source project management platform built around Scrum and Kanban. It includes boards, epics, sprints, issues, and a wiki, and can be run on your own infrastructure with Docker-based deployment.
Best For
Small engineering teams wanting a lightweight, open-source agile board in an isolated network without deep requirements traceability, cross-project reporting, or enterprise governance out of the box.
Capabilities and Data Boundary
Taiga is licensed under MPL-2.0 and supports Scrum, Kanban, issues, sprints, epics, a Kanban board, and a wiki. Authentication can integrate with LDAP and SAML. Project data stays on internal servers, with no vendor cloud dependency. The team controls upgrades, backups, database tuning, TLS, dependency patching, and disaster recovery.
Trade-off
Taiga is approachable for standups and task tracking, but its custom fields are basic and cross-project reporting is limited. Portfolio visibility and multi-team risk dashboards may require spreadsheets or external BI tools. Automation is also minimal: it has no native workflow agent or built-in AI assistant for progress summaries or risk analysis.
Avoid If
Avoid it if you need enterprise-grade access control, detailed audit trails, requirements-to-delivery traceability, mature workflow automation, structured review coordination, compliance evidence, or multi-layered governance.
