Authors can customize themes, fonts, CSS and HTML, use custom domains, and create multiple help sites or brands. Access controls include private sites, password protection, folder restrictions, conditional content, and IP restrictions; authentication options include SSO, SAML, and JWT. Reports cover article performance, search trends, failed searches, and author activity. It is accessible on laptops, tablets, and phones, and the mobile experience works without installing an app. The free plan supports one author and up to 25 pages. The pricing note lists paid plans from $0.99/user/mo (annual); the Essentials plan is also listed at $49 per author per month with annual billing and a 50-user minimum.

Wiki.js is a knowledge base for writing and sharing documentation, available as self-hosted software under the AGPL license. It can run in Docker, Kubernetes, or bare-metal environments on Linux, macOS, and Windows. Its editor supports Markdown with live preview, tables, tabsets, diagrams, math, and syntax highlighting for more than 180 languages. Authentication options include OIDC, LDAP, SAML 2.0, and local authentication; permissions can be granted, denied, and inherited across groups and page rules. Edits are attributed, compared, and restorable, and content can synchronize with Git or be pushed to local disk and cloud storage such as S3, Azure, and GCP. In version 3.0 beta, Wiki.js uses Node.js with PostgreSQL, adds real-time collaboration, and exposes user-interface actions as REST endpoints documented with OpenAPI. Stable releases require Node.js 18.x or later and a supported database, including PostgreSQL, MySQL, MariaDB, MSSQL, or SQLite3. The self-hosted plan is free forever.
