Best Wiki Software for Businesses
Choosing wiki software for a business is not a straightforward "best tool" decision. The right platform for a software company that already runs Jira is probably not the right platform for a government department with data sovereignty requirements, and neither of those is necessarily right for a small professional services firm that simply needs a searchable internal knowledge base without a dedicated IT function.
This article compares the platforms that appear most frequently in business evaluation shortlists - MediaWiki, Confluence, DokuWiki, BookStack, Notion, and XWiki - on the criteria that actually drive the decision: licensing model, hosting options, editing experience, access control, scalability, and total cost of ownership. The goal is a factual, balanced comparison that helps organisations identify the right fit for their specific situation, rather than a ranked list that treats every business as the same.
What to Look for in Business Wiki Software
Before comparing specific platforms, it is worth being clear about what business requirements actually matter when evaluating wiki software. The weight of each criterion varies by organisation, which is why the same question - "what's the best wiki software?" - has genuinely different correct answers depending on who is asking.
| Criterion | What It Means in Practice |
|---|---|
| Licensing and cost model | Is it free, per-user, or flat-rate? How does cost scale with users? Are there licensing lock-ins? |
| Hosting model | Self-hosted (you control the server), cloud-hosted (vendor controls infrastructure), or both options available? |
| Data ownership | Where does content live, and what happens to it if you stop paying or the vendor shuts down? |
| Editing experience | How much technical knowledge does day-to-day editing require? Is a WYSIWYG editor available? |
| Access control | How granular are read and edit permissions? Can different groups access different content areas? |
| Revision history | Is every edit tracked with authorship and timestamp? Can prior versions be restored? |
| Search capability | How well does full-text search work at the scale of content the wiki will hold? |
| Extensibility | Can additional functionality be added via extensions or integrations without custom development? |
| Maintenance burden | How much ongoing server administration, updating, and support does the platform require? |
| Ecosystem fit | Does the platform integrate with tools the organisation already uses? |
Platform Comparisons
MediaWiki
MediaWiki is free, open-source wiki software licensed under the GNU General Public License version 2 (GPLv2+). It is the platform that runs Wikipedia and thousands of other public and private wikis worldwide, including institutional deployments such as Intellipedia (used across the US intelligence community) and Diplopedia (used by the US Department of State). It is self-hosted software - there is no vendor-managed cloud version - and carries no per-seat licensing fee regardless of the number of editors or readers.
Strengths. MediaWiki's core advantage for large organisations is that cost does not scale with users. An organisation with 500 potential contributors pays no more in software licensing than one with 5. Its revision history model - every edit permanently recorded with full attribution, every prior version retrievable - is comprehensive by design, not as a premium feature. The extension ecosystem (over 1,000 listed extensions on MediaWiki.org) covers most enterprise requirements without custom development. And because content is stored in a standard relational database and exportable as XML, there is no vendor lock-in.
Limitations. MediaWiki requires real server administration. PHP runtime, database management, security patching, and upgrades all require either in-house technical capacity or an external technical partner. The default installation requires a custom skin to look like a branded business application rather than an unmodified Wikipedia clone. Access control for reading specific pages - as opposed to restricting editing - is more complex than on purpose-built enterprise platforms and typically requires the Extension:Lockdown extension for granular read permissions.
Best suited for. Large organisations with many potential contributors, institutions with data sovereignty requirements, organisations that need a full and permanent audit trail, and any business that wants to avoid per-seat licensing exposure as the user base grows.
Licensing cost. Free (GPLv2+). Infrastructure and maintenance costs apply.
Confluence
Confluence is Atlassian's commercial wiki and team documentation platform. It is the most widely deployed commercial wiki in enterprise environments and is deeply integrated with Atlassian's other products, particularly Jira. As of June 2026, Confluence Cloud pricing starts at no cost for teams of up to 10 users, with paid plans at approximately $6.40 per user per month (Standard) and $12.30 per user per month (Premium), billed annually.[1] Enterprise pricing is available on custom terms.
A note on hosting: Atlassian ended new Confluence Data Center subscriptions in early 2026, with existing Data Center licences subject to end-of-life timelines through 2029. Organisations evaluating Confluence for on-premises deployment should review Atlassian's current Data Center lifecycle policy before committing.[2]
Strengths. Confluence's user interface is polished and accessible to non-technical editors without training. Its Jira integration is genuinely strong for organisations that manage software development or IT service work. The platform includes templates, inline comments, structured spaces, and a comprehensive permissions model.
Limitations. The per-user pricing model means cost scales directly with the number of contributors, which can make Confluence expensive for large organisations. At 500 users on the Premium plan, annual costs are in the range of $65,000–$75,000 before marketplace add-ons. At 1,000 users, costs approach $100,000 or more annually. Organisations that have relied on the Data Center self-hosted option face a forced migration to Cloud under Atlassian's current product strategy. Practitioners consistently note that Confluence installations tend to accumulate disorganised content without active governance - a cultural and operational challenge rather than a pure product limitation, but a real one.
Best suited for. Organisations already standardised on the Atlassian ecosystem (Jira, Jira Service Management), teams with a moderate number of active editors where per-user costs remain manageable, and businesses that prioritise a polished UI and managed hosting over data sovereignty or cost predictability.
Licensing cost. Free up to 10 users; approximately $6.40/user/month (Standard) and $12.30/user/month (Premium) billed annually as of June 2026.
DokuWiki
DokuWiki is a free, open-source wiki engine licensed under the GNU GPL version 2. Unlike most wiki platforms, it stores content in plain text files rather than a relational database, which makes it exceptionally lightweight and means backups are as simple as copying a directory. It has been under continuous development since 2004 and has a large plugin ecosystem.
Strengths. DokuWiki's flat-file storage model means it requires almost no infrastructure - it can run on minimal shared hosting without a database. Setup is fast. Because content is stored as readable plain text files, it can be version-controlled with Git or backed up with a simple file copy. The platform has strong built-in authentication support including LDAP, which is relevant for businesses that need Active Directory integration.
Limitations. The plain text storage model that makes DokuWiki simple also limits it at scale - very large wikis with complex search requirements and many concurrent editors will find it less capable than database-backed platforms. The default editor is not as accessible for non-technical users as Confluence or BookStack. DokuWiki's interface is functional but shows its age compared to more modern platforms.
Best suited for. Small to medium technical teams, developer documentation, organisations that want a simple, low-maintenance internal wiki without database infrastructure, and businesses that want LDAP integration without the complexity of a full enterprise platform.
Licensing cost. Free (GPLv2). Infrastructure costs apply for self-hosting.
BookStack
BookStack is a free, open-source knowledge management platform built on PHP and the Laravel framework, released under the MIT licence. Created by Dan Brown, with its first commit in 2015, it has grown to become one of the most popular self-hosted wiki alternatives with over 16,000 GitHub stars as of mid-2025. It organises content in a fixed hierarchy: Shelves contain Books, which contain Chapters, which contain Pages.
Strengths. BookStack's book/chapter/page structure provides an immediately understandable content organisation model that works well for procedure manuals, policy documentation, and structured reference content. The editing experience - supporting both WYSIWYG and Markdown with a live preview - is accessible to non-technical users without training. The platform includes role-based permissions, LDAP and SAML2 authentication support, built-in diagram integration via Draw.io, and full-text search. It has shipped consistent monthly releases since 2015, demonstrating active and reliable maintenance.
Limitations. The fixed content hierarchy is both a strength and a constraint. Organisations that need highly flexible content organisation beyond the shelf/book/chapter/page model will find BookStack less accommodating. Its extension ecosystem is smaller than MediaWiki's or Confluence's, and advanced enterprise features - such as content approval workflows or complex custom namespace structures - are not available without custom development.
Best suited for. Small to medium organisations wanting a modern, user-friendly, self-hosted alternative to Confluence; teams building structured internal knowledge bases around well-defined topics; organisations that need LDAP/SAML2 authentication without the complexity of a full enterprise platform.
Licensing cost. Free (MIT). Infrastructure costs apply for self-hosting.
Notion
Notion is a cloud-based all-in-one workspace that can function as a team wiki, project planner, and document hub. It is hosted exclusively by Notion, with no self-hosting option. As of 2026, pricing is free for individuals, with team plans starting at approximately $10 per user per month (Plus) and $20 per user per month (Business), both billed annually. Enterprise pricing is available on custom terms.
Strengths. Notion's editing experience is genuinely flexible and accessible - pages support nested databases, inline tables, embeds, and a variety of block types that go beyond traditional wiki editing. For small teams or teams that want a single tool for notes, documentation, and lightweight project management, it is a practical choice.
Limitations. Notion has no self-hosting option. All content is stored on Notion's servers, which is a meaningful constraint for organisations with data residency, sovereignty, or security requirements. Revision history exists but is generally less comprehensive and central to the platform's identity than on purpose-built wikis like MediaWiki. Search quality can degrade at high content volumes. The per-user cost structure means expenses grow with team size.
Best suited for. Small teams, startups, and individual contributors who want a flexible, modern workspace without server administration overhead, and for whom cloud-only hosting is acceptable.
Licensing cost. Free (limited); Plus approximately $10/user/month; Business approximately $20/user/month, billed annually.
XWiki
XWiki is a mature, open-source enterprise wiki and application development platform. It has both a free community edition and commercial enterprise editions with paid support. It is self-hosted and is often positioned as a Confluence alternative for organisations that want enterprise-grade functionality without per-user licensing costs.
Strengths. XWiki's structured content model and scripting capabilities make it more adaptable for complex knowledge management requirements than most wiki platforms. It supports macro creation, custom application development within the wiki environment, and a comprehensive access control model. Its enterprise readiness - in terms of authentication options, audit logging, and governance features - is stronger out of the box than MediaWiki.
Limitations. XWiki is more complex to deploy and administer than BookStack or DokuWiki. Its community edition requires more configuration effort before it is useful as a business knowledge base. The scripting and application development capabilities that make it powerful also add complexity for organisations that simply need a well-organised internal wiki.
Best suited for. Medium to large organisations that need enterprise-grade wiki features and governance, are evaluating alternatives to Confluence, and have the technical capacity to administer a more complex platform. Particularly relevant for Confluence migrations where data ownership matters.
Licensing cost. Community edition free (LGPL). Enterprise and pro editions available with paid support.

How to Choose the Right Platform
No single platform is right for every organisation. The decision tends to come down to a small number of factors that vary significantly by context.
If per-user licensing cost at scale is a concern, the self-hosted open-source platforms - MediaWiki, DokuWiki, and BookStack - are the practical options. The cost of 500 or 1,000 contributors on Confluence or Notion grows quickly; on a self-hosted platform it does not.
If data sovereignty or on-premises hosting is a requirement, Confluence's Cloud-only direction rules it out for many regulated organisations, and Notion's cloud-only model does the same. MediaWiki, DokuWiki, BookStack, and XWiki all support full self-hosting.
If the editing population includes many non-technical users, the WYSIWYG-first platforms - Confluence, BookStack, and Notion - have lower barriers to contribution than MediaWiki's wikitext model, even with VisualEditor enabled.
If the organisation is already committed to the Atlassian ecosystem, Confluence's Jira integration provides real, day-to-day value that other platforms cannot easily replicate.
If the wiki will grow large, MediaWiki's namespace structure, extension ecosystem, and database-backed search scale more gracefully than flat-file or SaaS-limited alternatives.
If technical maintenance must be minimal, Confluence Cloud and Notion are the options that require no server administration. BookStack and DokuWiki sit in the middle ground - manageable without deep expertise, but not zero-maintenance.
Best Practices
Evaluate platforms against your actual use case rather than feature lists. A platform with 200 features that nobody uses is less valuable than a simpler one that genuinely fits how the organisation works. Before committing to any platform, run a structured pilot with a small group of actual intended editors - the editing experience and search quality only become clear in practice, not in vendor demonstrations. Budget honestly for the total cost of ownership, not just the software licensing line: self-hosted platforms require server infrastructure, maintenance time, and security patching that are real costs even if they don't appear on a software invoice. For any platform with per-user pricing, model the cost at two and five years at projected user growth, not just at current headcount. And plan for content governance from the start - the platform is only half the challenge; the other half is ensuring content stays current, accurate, and organised after launch.
Common Mistakes
Selecting a platform primarily because it is familiar - either because one person on the evaluation team knows it, or because a competitor uses it - without verifying it fits the organisation's actual requirements. Choosing a cloud-only platform without explicitly considering data sovereignty, then discovering mid-deployment that compliance requirements prevent using it. Underestimating the ongoing maintenance cost of self-hosted platforms and then under-resourcing them, which leads to deferred updates, security vulnerabilities, and eventually a forced migration. Selecting MediaWiki without a plan for custom branding, resulting in a generic, unmodified installation that editors don't trust or engage with. And treating the platform launch as the end of the project rather than the beginning - wiki quality degrades without ongoing content governance regardless of which platform was chosen.
Frequently Asked Questions
Is MediaWiki free for commercial business use?
Yes. MediaWiki is licensed under the GNU General Public License version 2 (GPLv2+), which permits commercial use without any licensing fee. The cost of a MediaWiki deployment is the server infrastructure, any customisation or setup work, and ongoing maintenance - not the software itself.
What is the cheapest wiki software for a business?
The cheapest in terms of software licensing are the open-source self-hosted platforms: MediaWiki, DokuWiki, and BookStack are all free to download and use. Total cost depends on infrastructure and maintenance, but for organisations with existing server capacity or modest traffic requirements, these platforms can be run at very low cost.
Is Confluence worth it for a small team?
Confluence's free plan supports up to 10 users and is a reasonable starting point for a small team already using Jira. Beyond 10 users, the per-seat model begins to accumulate. For a small team not already in the Atlassian ecosystem, BookStack or Notion often provide a more proportionate cost-to-capability ratio.
Which wiki software has the best revision history?
MediaWiki's revision history model is the most comprehensive among widely used wiki platforms - every edit is permanently stored with full authorship, timestamp, and a diff between versions, and no revision is ever deleted. This is the model Wikipedia uses and is by design rather than as a premium feature.
What replaced Confluence Data Center for on-premises deployments?
Atlassian ended new Confluence Data Center subscriptions in early 2026, with existing licences subject to a phased end-of-life timeline. Organisations that need a self-hosted, on-premises alternative are evaluating XWiki and MediaWiki as the most mature options, with BookStack suitable for smaller deployments.
How does MediaWiki compare to Confluence for an enterprise deployment?
MediaWiki has no per-user licensing cost, provides a complete and permanent revision history by default, is fully self-hosted, and has an extension ecosystem of over 1,000 extensions. Confluence has a more polished out-of-the-box editing experience, tighter Jira integration, and lower initial setup complexity. The tradeoff is per-user cost scaling, cloud hosting dependency, and vendor pricing control. For more detail, see "MediaWiki vs Confluence Comparison".
Conclusion
There is no single best wiki software for businesses - the right choice depends on the size of the contributing user population, data sovereignty requirements, technical maintenance capacity, existing ecosystem commitments, and budget. The most important thing is to evaluate platforms honestly against these factors rather than defaulting to the most familiar name.
For organisations that want full ownership of their data and infrastructure, no per-seat licensing exposure as contributors scale, and a platform with a demonstrated track record at institutional scale, MediaWiki is a strong and often underestimated choice. The investment required is real - server administration, proper setup, custom branding, and ongoing maintenance - but the operational and financial flexibility it provides is significant.
For organisations exploring MediaWiki as a platform, "What Is MediaWiki?" covers the fundamentals, and SolidWiki's MediaWiki Development Services page describes the specific setup, customisation, and maintenance work involved in deploying it for a business.
