See what XWiki offers: a free, open-source enterprise wiki for documentation and knowledge management, plus its app-building tools, pricing tiers, and features.
XWiki is an open-source enterprise wiki platform that has been under continuous development since 2004. It is built and maintained by XWiki SAS, a company based in Paris, France, and is distributed under the LGPL open-source license, meaning the core software can be downloaded, self-hosted, and used commercially without paying a license fee.
What sets XWiki apart from simpler wiki tools is its dual identity as both a documentation platform and an application framework. Pages can contain structured data, forms, and scripted macros, which means teams can build small internal applications, such as inventories, issue trackers, or approval workflows, directly inside the wiki rather than relying on a separate tool.
XWiki is commonly used by IT departments, universities, government agencies, and software teams that want an enterprise-grade knowledge base they fully control, either self-hosted on their own infrastructure or run on XWiki's managed cloud offering.
XWiki supports both WYSIWYG editing and wiki syntax, along with OpenDocument-based import and export, page annotations, tagging, and threaded comments, making it usable by both technical and non-technical staff.
Permissions are granular, letting administrators control access at the wiki, space, or individual page level, and every edit is versioned so changes can be reviewed or rolled back at any time.
The platform supports wiki farms, meaning a single installation can host many separate wikis for different teams or departments, and it exposes a RESTful API and extension marketplace so it can be integrated with external systems and extended with community-built applications.
Higher-tier commercial plans add single sign-on through OIDC or SAML, dedicated migration tooling from Confluence and SharePoint, and priority support with a named account manager.
The XWiki Community edition is entirely free and can be self-hosted with no cap on the number of users, which is the option most technical teams start with.
For organizations that want support, security patches, or managed cloud hosting, XWiki SAS sells four annual subscription tiers: Starter for up to 25 users on the cloud, Basic for up to 1,000 users on cloud or on-premise, Business for up to 10,000 users with SSO and migration tools, and Enterprise for unlimited users with advanced deployment support.
Professional services such as consulting and training are billed separately on a per-day basis, and open-source projects or NGOs can qualify for discounted support pricing and free entry-level cloud hosting.
