# Wiki.js

> Open-source wiki software built on Node.js with Git sync

Wiki.js is open-source wiki software, released under the AGPL-v3 license, that runs on your own server wherever Node.js is supported. Pages are written in a Markdown editor with live preview, a visual WYSIWYG editor or plain HTML, and every change is tracked so versions can be compared and restored. Modules for authentication, search and storage are switched on as needed, including content sync to Git services.

## Key features

- **Three editors:** Pages can be written in Markdown with a live preview, in a visual WYSIWYG editor meant for non-technical people, or directly in HTML.
- **Version tracking:** All content changes are tracked. Two versions of a page can be compared visually, and a page can be reverted to an earlier state or recovered after deletion.
- **Authentication modules:** Sign-in can use local accounts, services such as Google, GitHub and Slack, or LDAP, SAML, Okta and Azure AD, with two-factor authentication on supported modules.
- **Git and cloud storage sync:** Content can be synchronized or backed up to Git services such as GitHub and GitLab, or to storage such as AWS S3, Azure Blob Storage and Google Cloud Storage.
- **Groups, permissions and page rules:** Users are placed in groups with granular permissions, and page rules limit a group's access by exact path, by how a path starts or ends, or by regular expression.
- **GraphQL API:** A GraphQL endpoint on each wiki reads and modifies all of its resources, using API tokens with permission scopes that are generated in the administration area.

## Good for

- Developer teams that prefer writing documentation in Markdown
- Organizations that want a free wiki on their own infrastructure
- Wikis whose content should be mirrored to a Git repository

## Worth knowing

- The site offers two ways to run it, self-hosting or a DigitalOcean Marketplace image, and lists no managed hosting plan or paid support.
- It requires a dedicated domain or sub-domain and cannot be mapped to a subfolder of another site.
- MySQL, MariaDB, MS SQL Server and SQLite will not be supported in the next major version, which keeps only PostgreSQL.
- Version 3.0 is still in beta, and several listed modules, such as the WikiText and tabular editors, are marked as coming soon.
