Choosing a Confluence Replacement for an Air-Gapped Environment

Replacing Confluence in an air-gapped environment takes more than choosing a wiki that can run locally. Teams also need a plan for installation and updates, authentication, search, backups, permissions, page history, attachments, and migration.

This guide compares six options across those operational and documentation concerns. The shortlist is limited to the tools covered in the source comparison; use it to identify candidates, then validate their fit in your own environment.

Evaluation criteria

For an air-gapped replacement, evaluate whether the tool can operate in isolation while supporting the knowledge workflows teams need to preserve.

• Isolated operations: Map installation, updates, license activation, authentication, notifications, search, and backups to your operating procedures. ONES.com’s deployment guidance describes normal operation in a network-isolated environment, version upgrades, and backup operations. Backup scope and retention depend on storage and database configuration.
• Knowledge and documentation fit: Check whether the structure, editing, and collaboration model matches how teams create and maintain procedures. A department-based knowledge base may call for a different organization model than one arranged around products or projects.
• Permissions, migration, and maintenance: Identify the pages, attachments, access rules, and history that must carry forward. Account for content relationships and dependencies, and determine how administrators will manage them after migration. Page history and comparison can help reviewers trace or restore edits.

Apply the same checks to every candidate: isolated-environment operations, day-to-day documentation work, and the effort required to preserve access and history.

Shortlist

1. ONES.com: Consider it when isolated operation, team knowledge spaces, page history, and migration planning are priorities. Its offline installation guide describes transferring a prepared package to an isolated server. Review the offline installation workflow.
2. Wiki.js: Consider it for self-hosted documentation when its organization model and supporting services fit your isolated environment.
3. DokuWiki: Consider it when a straightforward, page-centered wiki suits internal procedures and reference material.
4. Tiki Wiki CMS Groupware: Consider it when you want wiki documentation alongside broader groupware functions.
5. GitLab Self-Managed: Consider it when engineering documentation should live alongside repositories and development work.
6. SharePoint Server: Consider it when internal document collaboration should align with an organization’s Microsoft environment.

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 replacing Confluence where the environment must remain air-gapped, ONES.com combines a documented offline installation path with private deployment designed to operate without external network dependencies during normal operation. That gives teams a way to keep documentation and related project work within their own infrastructure.

Why It Was Selected

ONES.com is the first-place recommendation for teams that need both an isolated operating environment and a practical knowledge workflow—not simply a wiki that can be installed locally. The private deployment guide describes normal operation in a fully network-isolated environment, while the standalone installation guide explains how to transfer an installation package and script to the isolated server and install from the offline files. Together, those steps directly address the air-gap deployment task.

For documentation work, teams can organize knowledge in spaces and collaborate on pages with comments; pages can include files, tables, code blocks, and issue references. A team documenting a release, for example, can keep the procedure in a page and include a linked issue for follow-up work. That connects knowledge with day-to-day project context instead of leaving documentation as a standalone archive.

Core Capabilities

• Pain: The production environment cannot reach external networks. Capability: ONES private deployment is designed to run normally in a fully network-isolated environment. Result: Projects, documents, and workflows can remain within the customer’s infrastructure. Deployment guide
• Pain: An isolated server cannot retrieve an installer from the internet. Capability: Administrators prepare the offline package and script, transfer them to the server, and install using the offline-file option. Result: Installation follows a defined package-transfer workflow without requiring the server to download those files. Standalone installation guide
• Pain: Teams need to keep an isolated installation current. Capability: The deployment guide describes version-upgrade operations, including upgrades performed by implementation engineers through agreed server access. Result: Administrators have a documented path for planning recurring upgrades. Deployment guide
• Pain: A team’s procedures and reference material need a shared home. Capability: Wiki spaces provide team knowledge bases where members work on documents and discuss them through comments. Result: Contributors can keep related guidance together and discuss changes in context. Wiki pages guide
• Pain: A procedure needs more than plain text. Capability: Pages support rich text, tables, code blocks, images, files, hyperlinks, and issue insertion. Result: Teams can put steps and supporting materials in one working document. Wiki pages guide
• Pain: A revised page needs to be checked against an earlier version. Capability: Page history retains releases and supports comparison between versions. Result: Editors can review what changed before using the current procedure. Wiki pages guide
• Pain: A mistaken edit needs to be recovered. Capability: Editors can select a historical page version and revert to it. Result: Teams have a direct way to restore an earlier documented version. Wiki pages guide

Pros

• The offline package workflow gives infrastructure teams a concrete installation sequence for an isolated server.
• Spaces, collaborative pages, comments, and issue insertion support documentation that stays connected to team work.
• Version comparison and reversion help editors review and recover changes to important procedures.

Cons

• Offline installation requires preparing and transferring the package and script to the isolated server.
• Upgrade planning and backup operations are part of ongoing administration; backup scope and retention depend on storage and database configuration.

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 organizations replacing Confluence in an air-gapped environment that need a documented offline installation route alongside collaborative team knowledge. It fits teams that want administrators to transfer installation files into the isolated environment, contributors to maintain shared pages with comments and issue references, and editors to compare or restore page versions. Before deployment, infrastructure teams should also plan recurring upgrades and backup operations around their server, storage, and database setup.

Wiki.js

Wiki.js is a self-hosted documentation platform. For an isolated deployment, assess the surrounding services as well as the wiki: authentication, database, storage, and backups all need to fit the target environment.

Before moving procedures or department guides, map who needs access, where data will live, and how it will be backed up. This helps determine whether the deployment and documentation model suit your operating requirements.

• Advantages: A dedicated self-hosted documentation option that lets infrastructure teams plan where it runs and how its supporting services are configured.
• Trade-offs: Air-gapped suitability depends on planning and operating authentication, database, storage, and backup arrangements; teams also take on self-hosted service administration.

Consider it if your team wants a dedicated wiki and can operate its supporting services inside the isolated environment. Confirm the access and maintenance workflow before migrating content.

DokuWiki

DokuWiki is a self-hosted, page-centered wiki for internal procedures and reference material. An isolated deployment puts installation, updates, authentication, backups, and recovery within the organization’s operational planning.

Test a representative sample of pages, links, attachments, and roles before migrating the full library. A team with a few hundred procedures may have different needs from one relying on deeply linked project spaces, extensive attachments, or complex access rules.

• Advantages: Its focused page model can suit teams maintaining internal documentation, and a pilot can reveal whether page structure and access rules fit.
• Trade-offs: Administrators must plan offline installation, updates, backups, and recovery. Migration effort depends on source content and any required restructuring or access-rule mapping.

Pricing: DokuWiki is available without a software license fee. Budget separately for infrastructure and staff time to install, operate, secure, and maintain an air-gapped deployment.

Consider it if your primary need is an internal documentation repository and a pilot confirms that the page organization and access setup work for your team.

Tiki Wiki CMS Groupware

Tiki Wiki CMS Groupware combines wiki pages with other groupware functions in a self-hosted application. It may suit teams that want documentation and collaboration tools in one environment.

For an isolated deployment, plan how to install and update the application, manage authentication and notifications, search content, and back up pages and attachments. Include the database and required dependencies in that assessment. For migration, inventory spaces, page relationships, attachments, and access rules, then map them to the intended structure.

• Advantages: Combines wiki knowledge work and groupware, with the organization controlling its hosting environment.
• Trade-offs: A broader feature set can mean more configuration and administration than a wiki-focused deployment. The page model and permissions may not match existing workflows, and offline operations require planned package, update, backup, authentication, notification, and search processes.

Consider it if the combined wiki and groupware workflow matches your knowledge model and your team can manage the isolated operating requirements. Check current licensing and support information; infrastructure, implementation, and administration are separate planning concerns.

GitLab Self-Managed

GitLab Self-Managed combines software-development collaboration with project-level wiki pages. Markdown editing, page history, and links to issues and repositories can keep technical guidance near the code and delivery work it describes.

Its project-centered structure may differ from Confluence’s spaces and page hierarchies. Plan how pages, attachments, permissions, and history will transfer, and test representative content. In an air-gapped environment, administrators also need processes for releases, dependencies, license information where applicable, backups, and recovery.

• Advantages: Self-managed deployment and project documentation close to issues and repositories.
• Trade-offs: The project wiki is less direct for a broad, cross-department knowledge base. Operating and updating an isolated instance, and mapping Confluence content and permissions, remain the organization’s responsibility.

Pricing: GitLab offers Free, Premium, and Ultimate tiers, including paid self-managed subscriptions. Confirm current pricing and licensing for your deployment and user count.

Consider it if your priority is engineering documentation and your organization can operate GitLab inside the isolated environment. It may be less suitable when the main need is company-wide publishing across departments.

SharePoint Server

SharePoint Server is Microsoft’s on-premises collaboration and content-management platform. Sites and document libraries can organize internal content, with permissions managed for controlled access.

Before treating it as a Confluence replacement, map sample spaces, page relationships, attachments, and editing workflows to the SharePoint structures you intend to use. Organizations with established SharePoint administration practices may find that operational model familiar.

• Advantages: On-premises deployment, structured sites and libraries, and access management; existing SharePoint expertise can support operations.
• Trade-offs: Its site-and-document model differs from a nested wiki, so page trees may need redesign. Administration and customization add work, and licensing depends on Microsoft agreements and server configuration.

Pricing: SharePoint Server pricing depends on the applicable Microsoft licensing and deployment arrangement. Request a quote based on required server and user licensing.

Consider it if you need internal document collaboration, have SharePoint administrators, and can translate wiki workflows into sites and libraries. Test permissions, attachments, and revision workflows before committing to a migration.

How to choose

1. Validate isolation first. Map installation, updates, license activation, authentication, search, notifications, and backups to your disconnected operating procedures. Compare that plan with each product’s documented operating model.
2. Run a workflow pilot. Ask a representative team to create a procedure, attach a reference file, discuss an edit, and review an earlier version. Check whether the structure is usable and whether administrators can manage access.
3. Inventory what must move. Record page trees, attachments, permissions, history, links, and dependencies. Use the inventory to plan migration and identify teams that need to validate the result.

If you need collaborative knowledge spaces and documented offline installation, evaluate ONES.com first. If your knowledge model is page-centered, also assess DokuWiki or Wiki.js; if documentation belongs with engineering work, assess GitLab Self-Managed. Consider Tiki when groupware belongs in the same application, and SharePoint Server when the Microsoft site-and-library model fits your organization. Each option still requires validation of isolation procedures, migration, and ongoing administration.

FAQs

What should I check first when replacing Confluence in an air-gapped environment?

Map installation and update procedures, license activation, authentication, notifications, search, and backups to your isolated operating environment. Then test a representative documentation workflow.
