Wikipedia runs on MediaWiki, the same free software any company can install for free on its own server. Confluence, by contrast, is Atlassian's corporate knowledge product — a publicly traded company that bills billions of dollars a year. Both solve the same problem, documenting what an organisation knows, but they start from radically different ownership and data-control models.
The usual comparisons between Confluence and MediaWiki focus on visual editors, templates and page permissions. Those matter, but they leave out the question we consider central at Democratic Market: when your team writes internal procedures, meeting notes or sensitive technical documentation, under which legal jurisdiction does that knowledge live, and who can request access to it?
Confluence: corporate knowledge as a service
Confluence launched in 2004 as Atlassian's second product. Atlassian was founded in Sydney in 2002 by Mike Cannon-Brookes and Scott Farquhar. The company keeps main offices in Sydney (Australia, EIU 8.86) and San Francisco (United States, EIU 7.85), but since 2022 its parent, Atlassian Corporation, has been incorporated in Delaware as a holding company, after moving away from its previous domicile in the United Kingdom. Legally, Confluence Cloud today operates under US law.
Atlassian has for years offered a data residency feature that lets you pin the storage location of Jira and Confluence Cloud to a specific region, including Frankfurt, for customers that need to keep their data within the European Union. In 2026 the company has also started rolling out its so-called Isolated Cloud, an extra layer of technical isolation that, as Atlassian's own documentation acknowledges, remains under US jurisdiction despite the infrastructure separation.
Why jurisdiction is still the right question
The 2018 CLOUD Act requires US tech companies to hand over data under a US court order, regardless of which country the servers physically sit in. The European GDPR regulates international transfers of personal data, and the 2023 EU-US Data Privacy Framework tries to give those transfers legal cover, even though its two predecessors were struck down by the EU Court of Justice.
In a corporate wiki, this carries an added dimension: it's not just employee personal data being stored, but also intellectual property, operational procedures and, in many cases, strategic information a company would rather not see exposed to a foreign government's access request, however remote the probability.
MediaWiki: free software, your own server, chosen jurisdiction
MediaWiki was originally built for Wikipedia and is now maintained by the Wikimedia Foundation, a non-profit headquartered in San Francisco. But MediaWiki itself isn't a service: it's GPL-licensed software that anyone can download, install and run on their own or a rented server, without depending on Wikimedia's infrastructure or any US company.
That distinction changes the whole analysis. A European company can install MediaWiki on a server in Germany (EIU 8.58), the Netherlands (EIU 9.01) or Finland (EIU 9.20), and its data will be subject exclusively to GDPR and the law of the chosen country. German companies such as BlueSpice have for years offered enterprise-grade MediaWiki distributions with support, backups and additional extensions, keeping both the software and the data entirely within Europe.
Democratic analysis: who chooses your knowledge's home address
Applying Democratic Market's logic, the question isn't just what EIU score the country where the company was founded has, but who actually controls where the data lives in practice. Confluence lets you pin a storage region, but the ultimate decision over how that infrastructure evolves, which cloud providers Atlassian uses, and which law the parent company answers to remains outside the customer's hands.
MediaWiki shifts that control entirely to the user. The company installing it decides the country, the hosting provider and the exact encryption and access conditions. No US corporation sits in the decision chain, unless the company itself voluntarily chooses a US-based hosting provider.
This doesn't make Confluence a bad option by definition. Atlassian, as a dual-headquartered company in Australia and the United States, operates from two jurisdictions that comfortably clear the EIU index's 6.0 threshold. The question is one of degree: self-hosted MediaWiki in Europe offers more direct jurisdictional control than any data residency setting from a US provider, however sophisticated.
There's also a timing nuance worth watching: the terms of service for large SaaS platforms change more often than many companies review their contracts. A data residency feature available today can be reconfigured, made more expensive, or restricted to higher-tier plans tomorrow, with the customer having no real leverage beyond cancelling the contract. With self-hosted software, that risk disappears: the terms are set by the organisation itself, not by a third party with shifting commercial interests.
Migration and vendor dependence
A factor that rarely appears in corporate wiki comparisons is what happens the day you want to leave. Confluence lets you export whole spaces in formats like XML or PDF, but Atlassian's proprietary internal structure of macros and templates doesn't always translate faithfully to other platforms, creating real migration friction even though the content itself isn't technically locked away.
MediaWiki, being the format in which a large share of the free knowledge on the internet is already written, has the best-documented export and import path on the market: MediaWiki's XML export format is the same one Wikipedia uses for its full public data dumps, and dozens of conversion tools, both inbound and outbound, have natively supported it for well over a decade.
This isn't a minor detail from Democratic Market's perspective: a tool that makes leaving easy by design hands you back negotiating power against the vendor, while one that makes leaving hard — even unintentionally — reinforces dependence, regardless of where the data happens to be stored in the meantime.
Technical comparison: features, price and democratic profile
Confluence offers a polished visual editor, native integration with Jira to link documentation to development tickets, corporate templates, automatic version control and a gentle learning curve for non-technical teams. Its pricing is structured per user per month, with very limited free tiers and paid plans that scale with team size.
MediaWiki is free as software, but not free as a service: it requires a server, someone to keep it updated, and, for a comfortable editing experience for non-technical users, extensions such as VisualEditor. The real cost sits in hosting — from a few euros a month on a basic European provider — and in administration time, not in licences.
Confluence has, since 2024, integrated AI features — Atlassian Intelligence — to summarise pages and suggest content, trained and run entirely within Atlassian's infrastructure. MediaWiki doesn't natively bundle AI, but its extension ecosystem, the same one Wikipedia runs on, includes SemanticMediaWiki for structured data and dozens of community-built add-ons anyone can audit before installing.
Certifications and real-world deployment examples
Atlassian holds ISO 27001 certification, SOC 2 Type II and SOC 1 Type 2 attestations for Jira and Confluence, plus FedRAMP authorisation for US government environments. It's a centrally managed compliance package that covers every customer equally, and that no individual customer can modify.
On the MediaWiki side, the German company Hallo Welt! GmbH develops BlueSpice, an enterprise MediaWiki distribution used in over 150 countries, with cloud hosting based in Germany or fully on-premises installation, built explicitly for public sector bodies and regulated companies that need sovereign knowledge infrastructure. In this model, security certification isn't provided by a single vendor — it's chosen by the organisation together with whichever data centre it contracts.
EU legislation that applies in 2026
The EU Data Act, being phased in progressively since September 2025, requires cloud service providers to facilitate data portability and reduce technical and contractual barriers to switching providers. This indirectly benefits any company relying on Confluence, by strengthening its right to export its documentation without artificial friction should it decide to migrate to a self-hosted alternative like MediaWiki.
How Democratic Market evaluates this kind of tool
For corporate documentation software we apply three layers of analysis: the jurisdiction of the company providing the service, whether the customer can choose or change that jurisdiction, and whether it's possible to do without an external provider entirely through auditable, self-hosted software. The more layers of control the end user has, the better the tool scores under our criteria.
Both Atlassian and the Wikimedia Foundation operate from countries scoring well above 6.0 on the EIU index, so neither option is excluded by origin. The relevant democratic difference lies in the model: a managed service with configurable residency versus free software with fully elective jurisdiction.
This methodology applies consistently across the rest of the software catalogue we evaluate at Democratic Market: we don't score a company worse for being American or Australian, but for how many real options it gives its European customers to decide where their information lives. A vendor headquartered in a high-EIU country but offering no configurable residency option at all scores worse, under our methodology, than one headquartered in the same country that does offer that lever.
This same effective-control criterion is what we apply when comparing other categories of business software at Democratic Market, from CRM platforms to cloud storage: it isn't enough to look at the EIU score of the company's country of origin — you also have to ask who actually decides, in day-to-day practice, where the data is processed and stored, and how easily that decision can be reversed if circumstances change.
It's a criterion that scales with the sensitivity of what you're documenting, not a blanket rule. A marketing team's public-facing style guide carries a very different risk profile from a legal team's litigation notes or an engineering team's incident postmortems, and it's entirely reasonable to run different tools, under different jurisdictional guarantees, for each of those use cases within the same organisation.
None of this is meant to suggest Confluence is an unsafe choice — millions of teams, including plenty of European public institutions, run their documentation on it every day without incident. The point is narrower: when jurisdiction genuinely matters for your organisation, know exactly which levers you have, which ones you don't, and which ones only self-hosting can give you. Make that call deliberately, document it, and revisit it whenever your regulatory context or client base changes.
Practical buying guide
If your team is small, non-technical, and needs to start documenting today with no friction, Confluence remains the fastest option to get running: configure EU storage region from day one if you have European customers or employees with data residency requirements.
If your organisation handles especially sensitive information — source code, contracts, regulated procedures — and has in-house technical capacity or a trusted provider, evaluate self-hosted MediaWiki on a European data centre. The upfront setup investment is offset by full control over where your company's knowledge lives.
Either way, export periodic copies of your documentation in an open format. The EU Data Act strengthens that right, but testing it yourself with a trial export is the only way to confirm you aren't locked into a given provider the day you decide to switch.
There's also a middle path many European organisations overlook: contracting a professionally supported enterprise MediaWiki distribution, such as BlueSpice, instead of managing raw software yourself. This reduces the technical friction of standing up your own wiki almost to the level of signing up for Confluence, while keeping the full jurisdictional control that self-hosted free software offers.
It's also worth planning permissions from day one, regardless of which tool you choose. Confluence organises access by Atlassian spaces and groups; MediaWiki does it through permission-management extensions like Lockdown or CheckUser, more flexible but requiring explicit manual configuration. A poorly permissioned wiki is a bigger information-leak risk than any jurisdictional difference between providers.
It's worth mentioning the human factor: adopting self-hosted MediaWiki usually requires a modest internal training effort to get non-technical teams comfortable with an interface different from Confluence's. That adoption cost is real and shouldn't be underestimated, but it's paid once, whereas dependence on a managed provider is paid month after month, indefinitely, for as long as the tool stays in use. Budget for that one-off training cost explicitly rather than treating it as a hidden surprise partway through the rollout.
Conclusion: knowledge also has a home address
Confluence and MediaWiki solve the same problem from opposite ends of the control spectrum: a managed service with residency options versus free software with fully electable jurisdiction. Neither company is born in an autocracy here, but only one of the two options lets you decide, without relying on a provider's goodwill, which country your organisation's accumulated knowledge lives in.
