xWiki vs Confluence: The Definitive Enterprise Wiki Comparison for 2026

The enterprise wiki landscape shifted permanently in September 2025 when Atlassian confirmed the end-of-life timeline for Confluence Data Center. As of March 30, 2026, no new Data Center subscriptions can be purchased. Existing licenses will lose expansion rights by March 30, 2028, and on March 28, 2029, every Confluence Data Center instance enters a permanent read-only state. For the thousands of organizations that chose self-hosted Confluence precisely because they needed control over their data, infrastructure, and compliance posture, this timeline presents a clear fork in the road: migrate to Atlassian Cloud, or adopt an alternative that preserves the sovereignty and flexibility they built their workflows around.

xWiki vs Confluence is the comparison that lands on the desk of every IT director facing this decision. xWiki is the leading open-source enterprise wiki platform — built on Java, backed by more than twenty years of continuous development, trusted by over 800 organizations worldwide, and equipped with purpose-built migration tooling that has already moved more than 100 Confluence instances to xWiki with full content fidelity. It is not a startup experiment. It is a mature, extensible, standards-compliant platform that treats data sovereignty as a first-class feature rather than an afterthought.

MassiveGRID is an official xWiki hosting partner. We operate managed xWiki deployments on high-availability infrastructure across data centers in Frankfurt, London, New York, and Singapore, giving organizations a turnkey path from Confluence to a self-hosted, compliant wiki without the overhead of managing bare metal themselves. This guide is the definitive side-by-side comparison to help you make that decision with confidence.

The Confluence Landscape in 2026

Confluence has been the default enterprise wiki for nearly two decades. Atlassian built a formidable ecosystem around it — Jira integration, a rich marketplace, and a familiar editing experience that became second nature to product teams, engineering organizations, and knowledge workers across every industry. For much of that history, organizations could choose between Confluence Cloud (hosted by Atlassian) and Confluence Server or Data Center (self-hosted). That choice is disappearing.

Atlassian ended Confluence Server sales in February 2021 and terminated Server support entirely in February 2024. Data Center was positioned as the successor for self-hosted deployments, but Atlassian has now confirmed that Data Center itself is on a sunset path. The critical dates every affected organization needs to understand are as follows:

March 30, 2026 — Atlassian stops selling new Confluence Data Center subscriptions. Organizations that do not already hold a license cannot purchase one after this date. This is, effectively, the closure of the self-hosted Confluence market.

March 30, 2028 — Existing Data Center customers lose the ability to add users or expand their license tier. Your team can continue using the platform, but growth is frozen. Any organizational expansion that requires additional seats will need to be served by a different product.

March 28, 2029 — All Confluence Data Center instances enter a permanent read-only state. Users can view existing content but cannot create, edit, or delete pages. Effectively, your wiki becomes an archive. No new knowledge can be captured, no documentation can be updated, and no collaborative editing can take place.

Read-only does not mean offline. Your data remains accessible, and Atlassian has indicated that security patches may continue for a limited window. But the practical reality is stark: a read-only wiki is a dead wiki. Knowledge management is inherently dynamic. The moment your team cannot update a runbook, revise a policy document, or add notes to an incident postmortem, the platform ceases to serve its core purpose. For a more detailed breakdown of the end-of-life timeline and what it means for your organization's migration planning, see our dedicated guide: Confluence Data Center End of Life 2029 — What You Need to Know.

xWiki at a Glance

xWiki is an open-source enterprise wiki platform licensed under the LGPL (GNU Lesser General Public License). It was first released in 2004, making it one of the longest-running wiki platforms in active development — predating Confluence Cloud by several years. The platform is built on Java, runs on any standard application server (Tomcat, Jetty, or within a Docker container), and uses a relational database backend (PostgreSQL, MySQL, MariaDB, Oracle, or HSQLDB). It is designed from the ground up for extensibility, multi-tenancy, and enterprise-grade access control.

At its core, xWiki provides a structured wiki with real-time collaborative editing (WYSIWYG and wiki syntax), nested page hierarchies, full-text search powered by Solr, and a macro system that allows content authors to embed dynamic elements — charts, forms, live data queries, and application components — directly into wiki pages. The App Within Minutes feature allows non-developers to create structured data applications (asset trackers, project registries, onboarding checklists) using a drag-and-drop interface, with no code required.

The extension ecosystem comprises over 900 extensions available through the xWiki Extension Manager, covering integrations with LDAP, Active Directory, SAML 2.0, OpenID Connect, Keycloak, and other identity providers. Enterprise features include granular page-level and space-level permissions, wiki-level isolation for multi-tenant deployments, PDF export, notifications, activity streams, and an extensive REST and scripting API that supports Velocity, Groovy, and Python for server-side automation.

xWiki supports over 40 languages out of the box, with a community-maintained translation framework that covers both the platform UI and documentation. Multi-tenancy support means a single xWiki installation can host multiple isolated wikis — each with its own user base, permissions, branding, and content — making it suitable for organizations that need to serve distinct business units, clients, or departments from a shared infrastructure.

The xWiki project also maintains a strategic partnership with OpenProject, the leading open-source project management platform. This partnership delivers a native integration between xWiki and OpenProject that mirrors the Confluence-Jira relationship — linking wiki documentation to project tasks, work packages, and timelines — but within a fully open-source stack that organizations can self-host without per-user licensing fees. For a deeper look at this pairing as a complete Jira-plus-Confluence replacement, see OpenProject + xWiki: The Open-Source Jira & Confluence Alternative.

Feature-by-Feature Comparison

The following table provides a direct comparison of xWiki and Confluence across the dimensions that matter most to enterprise decision-makers. Where a feature exists in both platforms but differs in implementation, the notes column clarifies the distinction.

Key Differentiators Worth Expanding

Data sovereignty deserves particular attention. When you self-host xWiki, your data never leaves your infrastructure. It sits on servers you control, in a jurisdiction you choose, subject only to the laws of that jurisdiction. Confluence Cloud, by contrast, stores data in AWS regions managed by Atlassian. While Atlassian offers data residency options for certain regions, the underlying infrastructure remains subject to the US CLOUD Act, which grants US law enforcement the authority to compel disclosure of data stored by US-headquartered companies regardless of where the servers are physically located. For European organizations operating under GDPR, Schrems II, NIS2, or DORA, this distinction is not academic — it is a compliance requirement.

Extensibility is another area where the platforms diverge in philosophy. Confluence's marketplace is larger in raw numbers, but many of its most useful apps carry their own per-user subscription fees, which can significantly increase the total cost of ownership. xWiki's extension ecosystem is entirely open source. Extensions are installed through the built-in Extension Manager, and because xWiki exposes a full scripting API (Velocity, Groovy, Python), organizations can build custom functionality directly within the platform without packaging and deploying a separate app. This makes xWiki particularly attractive to engineering-led organizations that value the ability to adapt their tools to their workflows rather than the reverse.

Multi-tenancy is a native capability in xWiki that has no direct equivalent in Confluence Cloud. A single xWiki installation can host multiple fully isolated wikis, each with its own user directory, permissions model, and branding. This is valuable for managed service providers, consulting firms that serve multiple clients, and large enterprises that need to provide isolated knowledge bases to distinct business units without deploying and maintaining separate instances.

Total Cost of Ownership

Licensing cost is the most visible line item, but total cost of ownership encompasses infrastructure, support, extensions, and the hidden costs of vendor lock-in. Understanding the full picture is essential before committing to a multi-year platform decision.

Confluence Cloud Pricing (2026)

Atlassian prices Confluence Cloud on a per-user, per-month basis, with tiered pricing that decreases per user as the total count increases. However, at enterprise scale, the aggregate cost is substantial. The following estimates reflect published list pricing as of early 2026:

These figures do not include Atlassian Access (required for SAML SSO and SCIM provisioning — approximately $4/user/month at scale), Marketplace app subscriptions, or premium support tiers. An organization with 1,000 users running Confluence Cloud Premium with Atlassian Access and a modest set of Marketplace apps can easily reach $130,000 to $160,000 per year in recurring costs.

xWiki Pricing Model

xWiki itself carries no per-user licensing fee. The software is free to download, install, and run on any infrastructure. Costs come from three areas: infrastructure (servers, storage, networking), optional commercial support from xWiki SAS (the company behind xWiki), and staff time for administration. For organizations that prefer a managed deployment, hosting partners like MassiveGRID bundle infrastructure, support, and maintenance into a single monthly cost that is typically a fraction of the equivalent Confluence Cloud spend.

Three-Year TCO Comparison

Consider a mid-size organization with 500 users. Over three years, Confluence Cloud Premium costs approximately $146,250 in subscription fees alone — before Atlassian Access, Marketplace apps, or support upgrades. The same organization running xWiki on managed infrastructure with commercial support from xWiki SAS and managed hosting from a provider like MassiveGRID can expect a three-year total cost that is 50 to 70 percent lower, depending on infrastructure requirements and support tier. The savings scale with user count: at 1,000 or 5,000 users, the gap widens further because xWiki's cost model is infrastructure-bound, not user-bound.

Hidden costs also favor xWiki in the long term. Confluence Cloud's pricing model means that every new employee, contractor, or external collaborator added to the platform increases the recurring cost. xWiki's model is usage-agnostic — you scale infrastructure to meet demand, but the software itself imposes no penalty for adding users. For a detailed breakdown of three-year TCO scenarios across multiple team sizes, see Confluence Cloud vs. xWiki: Total Cost of Ownership Comparison.

Migration Path: Confluence to xWiki

Migration is the highest-stakes phase of any platform transition. Content fidelity, user mappings, attachment handling, and macro compatibility all need to be preserved. xWiki has invested heavily in making this process reliable, repeatable, and well-documented.

The primary tool is Migrator Pro, a purpose-built migration application developed and maintained by xWiki SAS. Migrator Pro connects directly to a Confluence instance (Server, Data Center, or Cloud via API), extracts content — pages, spaces, attachments, comments, labels, and user references — and imports it into xWiki with structural fidelity. The tool has been tested and refined across more than 100 production migrations, ranging from small team wikis to large enterprise deployments with tens of thousands of pages.

A critical component of content fidelity is macro handling. Confluence relies heavily on macros — code blocks, table of contents, panels, status badges, page trees — and many of these have no direct equivalent in other platforms. xWiki addresses this through 31 bridge macros that replicate the behavior and rendering of the most commonly used Confluence macros. Content that was authored using Confluence macros renders correctly in xWiki without requiring manual intervention or bulk search-and-replace operations.

The migration process follows a structured workflow. First, a discovery phase maps the source Confluence instance — space inventory, content volume, macro usage, user directory, and permission model. Second, a test migration runs against a staging xWiki instance to validate content fidelity and identify any edge cases (custom macros, third-party app content, or non-standard formatting). Third, after validation, the production migration is executed, typically during a maintenance window. Finally, a post-migration verification phase confirms that all content, permissions, and user mappings are intact.

For organizations running Confluence Data Center with large content volumes, the migration can be performed incrementally — migrating spaces in batches to minimize downtime and allow parallel validation. MassiveGRID supports migration planning and execution for customers deploying on our managed xWiki infrastructure, including staging environments for test migrations and dedicated support during cutover windows. For a step-by-step walkthrough of the migration process, see How to Migrate from Confluence to xWiki: A Step-by-Step Guide.

Data Sovereignty and Compliance

Data sovereignty has moved from a niche concern to a board-level priority. Regulatory frameworks in Europe, the Middle East, and Asia-Pacific increasingly mandate that sensitive organizational data — internal documentation, policy records, technical knowledge bases, and employee communications — must reside within specific jurisdictions and remain under the direct control of the data-owning organization. A cloud-hosted wiki operated by a US-headquartered vendor introduces structural compliance risks that self-hosted alternatives eliminate entirely.

GDPR and Schrems II

The General Data Protection Regulation requires that personal data of EU residents be processed and stored in accordance with EU law. The Schrems II ruling (2020) invalidated the EU-US Privacy Shield and imposed strict requirements on any transfer of personal data to countries without an EU adequacy decision. While the EU-US Data Privacy Framework (2023) restored a legal basis for certain transfers, its durability remains uncertain — and many organizations, particularly in regulated sectors, prefer to eliminate transatlantic data flows entirely rather than rely on a framework that could be challenged again. Self-hosting xWiki within the EU removes this variable completely.

NIS2 and DORA

The NIS2 Directive (effective October 2024) and the Digital Operational Resilience Act (DORA, effective January 2025) impose new cybersecurity and operational resilience requirements on a broad range of European organizations, including financial institutions, healthcare providers, energy companies, and digital service providers. Both frameworks emphasize supply chain risk management, data protection, incident reporting, and the ability to demonstrate control over critical ICT systems. A self-hosted wiki on infrastructure you own and operate — or on managed infrastructure provided by a European hosting partner with documented compliance posture — aligns directly with these requirements. Confluence Cloud, as a third-party SaaS dependency, introduces supply chain risk that must be formally assessed and documented under both NIS2 and DORA.

For organizations in the financial sector, our guide on xWiki and DORA Compliance for Financial Services provides a detailed mapping of xWiki's capabilities to DORA requirements. For broader NIS2 compliance, see xWiki for NIS2-Compliant Knowledge Management. Government and public-sector organizations should review xWiki for Government: Digital Sovereignty in Knowledge Management.

MassiveGRID Infrastructure for Compliant Deployments

MassiveGRID operates data centers in Frankfurt, London, New York, and Singapore. Our Frankfurt facility is the preferred deployment target for organizations with EU data residency requirements — all data remains within the European Union, on infrastructure operated by a company with no US-headquartered parent entity exposure. Our infrastructure is built on high-availability architecture with automated failover, encrypted storage, and ISO 9001-aligned operational processes. For organizations that need to demonstrate compliance with DORA, NIS2, or digital sovereignty mandates, we provide documentation and infrastructure attestations to support audit and procurement processes. For a hosting-focused guide, see Hosting xWiki in European Data Centers: A GDPR Compliance Guide.

Who Should Switch — and Who Should Stay

Not every organization needs to leave the Atlassian ecosystem. The right decision depends on your specific requirements around data sovereignty, cost structure, extensibility, and operational control. Here is an honest framework for evaluating the choice.

Switch to xWiki If

You should seriously evaluate xWiki if your organization falls into any of the following categories. First, if you are currently running Confluence Data Center and value the ability to self-host your knowledge base on infrastructure you control, xWiki is the most mature open-source replacement with proven migration tooling. Second, if your organization operates in a regulated industry — financial services, healthcare, government, defense, critical infrastructure — where data sovereignty, auditability, and supply chain control are compliance requirements, not preferences, then a self-hosted wiki eliminates an entire category of vendor risk. Third, if your Confluence Cloud costs are growing faster than your team, and you are paying for Atlassian Access, Premium support, and a stack of Marketplace apps on top of per-user license fees, xWiki's infrastructure-bound cost model can deliver significant savings, especially at 500 or more users. Fourth, if you need multi-tenancy — serving multiple isolated wikis for different business units, clients, or departments from a single platform — xWiki provides this natively, while Confluence requires separate instances. Fifth, if your engineering team values extensibility and the ability to customize the platform through scripting, APIs, and open-source extensions rather than being constrained to vendor-approved apps, xWiki's architecture is built for this from the ground up.

Stay on Confluence Cloud If

Confluence Cloud remains a reasonable choice in certain scenarios. If your organization has no regulatory requirement for data sovereignty and is comfortable with Atlassian hosting your data on their infrastructure, the managed nature of Cloud removes operational overhead. If your team is deeply embedded in the Atlassian ecosystem — Jira Cloud, Bitbucket Cloud, Trello, Statuspage — and the integration between these tools is a core part of your daily workflow, the switching cost of moving away from the ecosystem may outweigh the benefits for your specific situation. If your team is small (under 50 users) and your Confluence Cloud bill is modest, the cost savings from switching to a self-hosted alternative may not justify the migration effort. And if your organization does not have the internal capability or budget for managed hosting to operate self-hosted infrastructure, and you prefer the simplicity of a vendor-managed SaaS product, Confluence Cloud removes that operational responsibility.

This is not an all-or-nothing decision. Some organizations adopt xWiki for their compliance-sensitive content while maintaining Confluence Cloud for less regulated teams. Others use the Confluence Data Center end-of-life timeline as a forcing function to evaluate their entire toolchain — replacing both Confluence and Jira with open-source alternatives like xWiki and OpenProject.

Next Steps: Making the Move

If your organization is evaluating xWiki as a Confluence replacement, the most productive first step is a proof of concept. Stand up a test instance, run a trial migration of a representative space, and let your team experience the platform firsthand. The xWiki community provides comprehensive documentation, and Migrator Pro makes it straightforward to test the migration path with your actual content.

For organizations that want to move quickly without managing infrastructure, MassiveGRID's managed xWiki hosting provides a production-ready deployment on high-availability infrastructure, with migration support, automated backups, and 24/7 monitoring included. We handle the infrastructure so your team can focus on evaluating the platform, planning the migration, and onboarding users.

Whether you are facing the Confluence Data Center deadline, re-evaluating your wiki costs, or responding to new compliance requirements, the decision deserves a thorough, informed comparison. We have built this guide to provide that foundation. If you have questions specific to your environment — user count, content volume, compliance requirements, integration needs — reach out to our team for a consultation. We are here to help you make the right choice for your organization, not to sell you a platform you do not need.

Frequently Asked Questions

Is xWiki a good alternative to Confluence?

Yes. xWiki is the most mature open-source enterprise wiki platform, with over twenty years of active development, more than 900 extensions, and a feature set that matches or exceeds Confluence in areas including permissions granularity, multi-tenancy, data sovereignty, and extensibility. It is used by over 800 organizations worldwide, including enterprises in regulated industries such as financial services, healthcare, and government. The platform includes purpose-built migration tools (Migrator Pro) with 31 bridge macros that preserve content fidelity when moving from Confluence to xWiki.

Can I migrate from Confluence to xWiki?

Yes. xWiki SAS develops and maintains Migrator Pro, a dedicated migration tool that extracts content — pages, spaces, attachments, comments, labels, and user references — from Confluence Server, Data Center, or Cloud and imports it into xWiki. The tool includes 31 bridge macros that replicate the behavior of commonly used Confluence macros, ensuring content renders correctly without manual intervention. More than 100 organizations have completed production migrations using this tool. For a detailed walkthrough, see our step-by-step migration guide.

Is xWiki free?

The xWiki platform is free and open source, licensed under the LGPL. You can download, install, and run xWiki on your own infrastructure at no software cost, for an unlimited number of users. Optional commercial support is available from xWiki SAS, and managed hosting services are available from partners like MassiveGRID. There are no per-user license fees, no feature gating between free and paid tiers, and no usage-based pricing.

What happens when Confluence Data Center ends?

Atlassian has confirmed that Confluence Data Center will enter a permanent read-only state on March 28, 2029. Before that date, new Data Center subscriptions end on March 30, 2026, and license expansion ends on March 30, 2028. Once in read-only mode, users can view existing content but cannot create, edit, or delete pages. Organizations must plan to migrate to either Atlassian Cloud or an alternative platform before this deadline. See our detailed end-of-life guide for the full timeline and planning recommendations.

Does xWiki support LDAP and Active Directory?

Yes. xWiki provides native support for LDAP and Active Directory authentication, including group synchronization and automatic user provisioning. Additionally, xWiki supports SAML 2.0, OpenID Connect, Keycloak, and CAS for single sign-on integration. Unlike Confluence Cloud, which requires the paid Atlassian Access add-on for SAML SSO and SCIM provisioning, xWiki includes these authentication capabilities at no additional cost.

Is Confluence being discontinued?

Confluence as a product is not being discontinued. Atlassian continues to develop and sell Confluence Cloud. What is being discontinued is the ability to self-host Confluence. Confluence Server reached end of life in February 2024, and Confluence Data Center will enter read-only mode on March 28, 2029. After that date, the only supported version of Confluence will be the cloud-hosted edition managed entirely by Atlassian. Organizations that require self-hosted deployments will need to adopt an alternative platform.

What is replacing Confluence?

For organizations moving away from Confluence — whether due to the Data Center end of life, cost concerns, or data sovereignty requirements — xWiki is the leading open-source replacement. It offers comparable functionality (real-time editing, structured content, extensions, SSO), proven migration tooling, and the ability to self-host on any infrastructure. Other alternatives exist in the market, but xWiki is the only open-source platform with more than two decades of enterprise deployment history and a dedicated Confluence migration tool. Paired with OpenProject, it can also replace the Jira-Confluence combination entirely.

Is there a free version of Confluence?

Atlassian offers a free tier of Confluence Cloud for up to 10 users. This tier includes basic wiki functionality but excludes features such as advanced permissions, audit logging, SAML SSO (requires Atlassian Access), and premium support. For any team larger than 10 users, Confluence requires a paid subscription. By contrast, xWiki is fully free and open source for an unlimited number of users, with no feature restrictions in the community edition.

Why is Atlassian killing Data Center?

Atlassian has stated that moving all customers to cloud-hosted products allows them to deliver features faster, reduce the operational complexity of supporting self-hosted deployments, and invest more deeply in their cloud platform. From a business perspective, cloud subscriptions also provide more predictable recurring revenue compared to perpetual or term-based Data Center licenses. While the transition benefits Atlassian's product development and business model, it removes the self-hosting option from customers who chose Data Center specifically because they needed infrastructure control, data sovereignty, or compliance isolation — needs that Confluence Cloud does not address.
