Choosing a Self-Hosted Confluence Replacement: Migration, Operations, and Fit

Replacing Confluence in a self-hosted environment is not just a page-export problem. Your choice affects how people find information, how access is managed, and how much operational work your team takes on.

Migration deserves its own evaluation: pages can depend on attachments, links, permissions, or macros that a straightforward copy may not preserve. This guide compares eight options using four practical criteria: deployment and operating effort, knowledge structure and collaboration, access controls, and migration fit. Treat the shortlist as a starting point, then test representative content before planning a full transfer.

How to evaluate the options

• Deployment and operations: Confirm the deployment model fits your environment and account for setup and ongoing administration. For ONES.com, the self-hosted migration tool guide covers setup, network checks, space selection, user mapping, attachment copying, and index rebuilding.
• Knowledge structure and collaboration: Compare how people create, review, organize, and retrieve documentation. BookStack makes its shelves-to-pages hierarchy explicit; Wiki.js may be a closer workflow match for teams using Markdown and Git.
• Permissions and authentication: Map who should view, comment on, edit, or manage each space or page. ONES.com documents team- and space-level Wiki permissions, including view, comment, edit, space management, and page-level locking. See ONES Wiki permissions.
• Migration fit and testability: Check how the candidate handles pages, attachments, permissions, macros, and links. ONES.com’s Confluence migration assistant can preserve spaces, page trees, pages, attachments, and permissions; supported macros retain data or style, while unsupported macros become placeholders. Administrators can test a small space and review reports for migration issues and link repairs. See the Confluence migration guidance.

Use these criteria in sequence: establish operational fit, compare the everyday authoring and browsing workflow, then test migration on representative content before committing to a larger transfer.

Shortlist by use case

1. ONES.com: Start here if migration scope and results need a practical test. Administrators can assess Confluence usage, test a small space, and inspect reports before planning a broader transfer. Migration guidance
2. BookStack: Consider it when the team wants a clear hierarchy of shelves, books, chapters, and pages.
3. Wiki.js: Compare it for developer- and Markdown-focused workflows where Git integration is relevant; check editing and collaboration fit.
4. Outline: Shortlist it if a collaborative knowledge base is a priority and its self-hosted option fits your operating model.
5. DokuWiki: Consider it for a self-hosted, page-centered wiki.
6. MediaWiki: Evaluate it for large collections of linked reference pages.
7. Documize: Compare it when a structured document approach suits the work.
8. Redmine: Consider it when project tracking and wiki-style documentation belong together.

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 replacing Confluence with self-hosted deployment, ONES.com combines knowledge management with controlled on-premises deployment and a migration process designed to assess and transfer existing content. Its Confluence migration assistant is available for ONES Enterprise on-premises, supporting a planned transition of spaces, pages, attachments, users, and permissions. The migration guide also identifies how macros and space-homepage locks are handled, so administrators can plan around those details.

Why It Was Selected

ONES.com is the strongest fit here when your priority is moving a substantial Confluence knowledge base into a self-hosted environment without treating migration as a blind copy. Administrators can review usage—including space count, user count, data volume, attachment storage, and the largest space—plan scope and batches, test a small space, then use migration reports to inspect failed spaces, pages, attachments, users, and link repairs. That gives the team concrete checkpoints before expanding the transfer. The assessment guidance recommends self-service for deployments under 400 spaces and under 500 GB; larger environments are directed to assisted assessment and monitoring. See the migration assessment and reporting workflow.

This migration fit is paired with configurable knowledge access after the move: Wiki administrators can manage permissions across spaces, while space administrators configure viewing, commenting, editing, and space management. The result is a practical path from migration testing to day-to-day access control, with the operational work visible enough for teams to plan their rollout.

Core Capabilities

• Pain: A large Confluence estate is hard to scope from memory. Capability: Administrators assess space counts, users, data volume, attachment storage, and the largest space, then plan migration method and batches. Result: The rollout begins with a view of workload and environment requirements. Migration assessment details.
• Pain: A full migration can hide problems until too much content has moved. Capability: Administrators test a small space and review reports for failed spaces, pages, attachments, users, and link repairs. Result: The team can use observed results to adjust the next batch. Migration testing and reports.
• Pain: Rebuilding page trees manually disrupts familiar navigation. Capability: The migration assistant transfers spaces and pages while preserving page trees. Result: Readers can find documentation in an organized hierarchy after the move. Supported Confluence data.
• Pain: Teams rely on images, files, and other page attachments as part of instructions. Capability: The assistant migrates uploaded attachments and attachment files generated by some plugins. Result: Key supporting materials can travel with their pages; attachments over 300 MB require an operations change to the size limit. Attachment migration conditions.
• Pain: Macros can carry meaning or formatting that matters to readers. Capability: Supported macros retain data or style, while unsupported macros appear as placeholders. Result: Administrators can identify content that needs follow-up during migration review. Macro migration behavior.
• Pain: A transfer can leave access dependent on manual reconstruction. Capability: The assistant migrates user and group information and permissions, subject to documented exceptions. Result: Teams can carry forward much of their existing access structure for review. User and permission migration.
• Pain: Different teams need distinct rights to documentation. Capability: Wiki administrators configure permissions across spaces; space settings include view/comment, edit, and space-management controls. Result: Owners can align access with team responsibilities. ONES Wiki permission roles.
• Pain: Self-hosted migration requires operational preparation beyond selecting content. Capability: The separate migration-tool guide covers tool setup, network checks, space selection, user mapping, attachment copying, and index rebuilding. Result: Administrators can include these tasks in the migration plan and handoffs. Self-hosted migration setup.

Pros

• Migration guidance connects scope assessment, a small-space test, and report review, giving administrators observable checkpoints.
• Spaces, page trees, attachments, many permissions, and supported macro data or style are included in the documented migration workflow.
• Team- and space-level permission controls support access decisions after content is in place.

Cons

• Migration planning includes operational tasks such as environment capacity checks; the separate migration-tool procedure also includes attachment copying and index rebuilding.
• Unsupported macros become placeholders, and Confluence space-homepage lock permissions are not preserved, so those items need to be accounted for in migration review.

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 that need self-hosted deployment and a migration process they can stage and inspect. For example, an administrator can assess a Server or Data Center estate, test one space, review failures and link repairs, then move through planned batches while space owners configure access for their teams. It is especially relevant when the project needs an explicit migration plan alongside ongoing knowledge-base permissions and operations. The migration assessment supports Server and Data Center sources; supported Confluence versions include Server/Data Center 6.x, 7.x, and 8.x, plus Cloud, with contact support advised for other versions. Review supported sources and migration conditions.

BookStack

BookStack is a self-hosted knowledge base organized into shelves, books, chapters, and pages. This explicit hierarchy can make it straightforward to place and browse procedures, onboarding guides, and reference material.

Good fit: Teams that want a predictable structure and can map their content naturally into that hierarchy. Before moving a Confluence space, map representative content to shelves, books, chapters, and pages; separately confirm how source attachments, macros, permissions, and links will transfer.

Trade-offs: The book-like organization may not suit teams that need a highly flexible wiki structure. Complex Confluence spaces require mapping and migration checks rather than an assumed one-to-one transfer. BookStack is open-source software available for self-hosting; budget for infrastructure and operations.

Wiki.js

Wiki.js is a self-hostable wiki with multiple authentication and storage options. Its Markdown focus and Git integration make it relevant to teams that manage documentation as text files or as part of a version-controlled workflow.

Good fit: Technically oriented teams whose editors already work comfortably with Markdown and Git. Test a representative Confluence space and review page structure, editing, access, attachments, and links before deciding on a larger move.

Trade-offs: A Markdown-centered workflow may require adjustment for Confluence users. Git integration does not establish that macros, permissions, attachments, or links will transfer as intended. Administrators also need to choose suitable authentication and storage options and operate the self-hosted instance. The comparison lists Wiki.js as free; verify current project or vendor terms and account for infrastructure and administration.

Outline

Outline is a collaborative knowledge base for creating and organizing team documentation. Its fit as a self-hosted Confluence replacement depends on whether its available deployment options and operating requirements match your environment and whether its document workflow suits your pages and access needs.

Good fit: Teams prioritizing shared, editable documentation. Reproduce a small set of representative pages, including attachments and internal links, and have both maintainers and readers review the result.

Trade-offs: Self-hosting suitability depends on deployment choices and the team’s operating capacity. Migration effort varies with page structure, attachments, links, macros, and permissions, so test those rather than assuming a direct transfer. Check current pricing and deployment terms before choosing; the comparison lists free and paid options.

DokuWiki

DokuWiki is a self-hosted wiki with a direct, page-centered documentation workflow. Its plain-text storage makes page content accessible as files, while its wiki-centered approach provides a dedicated documentation destination.

Good fit: Teams that want to run a wiki on infrastructure they control and can pilot representative pages before committing. Test a page with attachments, links, and restricted access, then ask page owners to review both the imported material and its usability.

Trade-offs: The team owns server setup, updates, backups, and ongoing maintenance. Migration may require hands-on testing and cleanup for macros, attachments, links, and detailed permissions; evaluate the editing and collaboration experience with actual authors. DokuWiki is free and open-source software, apart from infrastructure and staff time.

MediaWiki

MediaWiki is an open-source wiki engine that can be installed on your own server. Its editable pages and internal links suit interconnected reference collections; page histories help contributors review changes, and extensions can adapt the installation to selected needs.

Good fit: Organizations able to operate their own wiki infrastructure and manage extension and upgrade decisions. Test a plain reference page alongside a procedure that uses attachments or restricted access, and review how content and relationships behave.

Trade-offs: Administrators own installation, configuration, upgrades, and maintenance; extensions add evaluation and upkeep. Teams should test formatting, macros, attachments, permissions, and links rather than assume a page-for-page transfer. MediaWiki has no license fee, but infrastructure and administration still have costs.

Documize

Documize is a self-hostable documentation platform centered on documents and shared knowledge. It can suit teams that want an organized home for internal procedures and reference material rather than a broader project-management replacement.

Good fit: Teams whose work can be organized around shared documents and whose organization can operate the deployment. Test representative Confluence pages, attachments, links, permissions, and macros to see whether the document structure preserves how the material is used.

Trade-offs: Heavily customized spaces need careful mapping, and self-hosting makes configuration and ongoing operation your responsibility. Teams seeking combined knowledge and project management may need additional tools. The comparison lists free and paid options; check current edition, deployment, and pricing terms directly.

Redmine

Redmine is an open-source project management application that can be self-hosted. It includes wiki functionality, but is best evaluated as a project and issue tracker with documentation—not as a direct replacement for every Confluence knowledge-base workflow.

Good fit: Teams that want project notes and work items in one application. Map representative pages and links to the intended Redmine wiki structure and check how editors and readers will find and update the material.

Trade-offs: Its project-oriented wiki may not work well for a large, deeply structured company knowledge base. The organization owns configuration, maintenance, backups, and upgrades, and migration depends on how pages, attachments, links, and access rules map to Redmine. Redmine is open-source; account for infrastructure and staff time.

A practical selection and migration path

1. Assign operational ownership. Decide who will provision, configure, update, back up, and support the self-hosted deployment. Rule out candidates your team cannot operate.
2. Match the workflow. Use an ordinary workday as the test. BookStack’s hierarchy suits teams wanting a visible path from collection to page; Wiki.js is more relevant when Markdown and Git match existing habits. Consider Redmine when project tracking and project-level documentation belong together.
3. Choose representative source content. Select a Confluence space with typical pages, attachments, permissions, macros, and links. Record what users rely on so the pilot checks more than whether text appears.
4. Run a migration pilot. For ONES.com, administrators can assess usage, test a small space, and inspect reports for failures and link repairs. Review supported and unsupported macro behavior before planning wider batches. See the Confluence migration workflow.
5. Verify access and operations. Map who can view, comment, edit, or manage each space and identify pages needing tighter controls. ONES.com documents team- and space-level permissions and page locking; its migration assistant can carry over many Confluence users, groups, and permissions, subject to documented exceptions. Include environment checks, attachment copying, and index rebuilding in the plan. See ONES Wiki permissions and the self-hosted migration tool guide.

Which option should you choose?

Consider ONES.com when you need self-hosted deployment alongside a documented, staged way to assess and test a Confluence migration, and when its operational requirements and pricing fit your organization. Choose BookStack when a simple, visible hierarchy matters more than flexible wiki organization. Compare Wiki.js when Markdown and Git align with your team’s documentation habits. Evaluate Outline for collaborative knowledge work, DokuWiki or MediaWiki for self-hosted wiki workflows, Documize for document-centered knowledge, and Redmine when project tracking should sit beside documentation.

No shortlist decision replaces a pilot. Test representative content and access rules, review what needs manual adjustment, and use those findings to scope the remaining transfer.

FAQ

What should I test before replacing Confluence with a self-hosted wiki?

Test a representative space containing typical pages, attachments, permissions, macros, and links. Review the resulting content and migration reports so the wider transfer can be planned around observed results.

Which option suits a simple documentation hierarchy?

BookStack is worth considering when the team wants a clear structure of shelves, books, chapters, and pages.

How should teams compare permissions?

Map who needs to view, comment on, edit, or manage each space, then check how the candidate applies those controls. ONES.com supports team- and space-level permissions and page-level locking.

What should I account for when self-hosting a migration?

Plan for environment checks and migration operations. The ONES self-hosted migration-tool guide describes setup, network checks, space selection, user mapping, a separate attachment-copy step, and index rebuilding.
