    Wiki.js

    29kmay 2026

    A modern wiki with enough knobs to remind you that you are now the administrator

    The catch vs Confluence

    It lacks Confluence's mature enterprise templates, macros, whiteboards, marketplace and Atlassian integrations, while shifting hosting and upgrades to you.

    21kaug 2026

    Confluence with less ceremony and a Docker bill

    The catch vs Confluence

    It is simpler and faster, but has fewer enterprise macros, workflow controls, templates, marketplace integrations and Jira-native connections than Confluence.

    Install, platforms & data +
    platforms
    webself-hosteddocker to self-host

    Hosted signup or Docker Compose with PostgreSQL and Redis
    setup
    Self-hosting requires Docker, a strong APP_SECRET, database credentials, persistent volumes, and normally a domain, TLS reverse proxy, and SMTP
    your data
    Pages, users, comments, and history in PostgreSQL; jobs/cache in Redis; attachments in a persistent local volume by default or S3/Azure Blob

    BookStack

    open sourceMITSelf-host
    19kjul 2026

    A wiki organized like a bookshelf; gloriously opinionated and much less flexible than Confluence

    The catch vs Confluence

    Its compulsory shelf/book/chapter structure and smaller extension surface are far less flexible than Confluence spaces, macros, databases, whiteboards and Jira-connected workflows.

    Install, platforms & data +
    platforms
    webself-hosteddocker to self-host
    install
    Fresh Ubuntu install script or manual PHP/MySQL setup
    setup
    The official script expects a fresh Ubuntu host; manual installs require PHP extensions, a database, writable storage, mail, and TLS
    your data
    Pages, users, permissions, and settings in MySQL/MariaDB; uploaded images and files in the server filesystem or configured object storage

    XWiki

    open sourceLGPL-2.1Self-host
    1.3kaug 2026

    Confluence's grown-up open-source cousin; powerful enough to require an actual administrator

    The catch vs Confluence

    It can approach Confluence's depth, but doing so carries a much heavier Java/Solr/database administration burden and less seamless Atlassian ecosystem integration.

    Install, platforms & data +
    platforms
    webself-hostedself-host, real ops
    install
    Official Docker Compose stack, Debian package, or Java application-server distribution
    setup
    The production setup is a heavyweight Java service with a database, permanent storage, Solr, backups, and TLS to administer
    your data
    Wiki documents, objects, users, metadata, and usually attachments in a relational database; configuration, extensions, caches, and optional attachment files in the permanent directory
