Alternatives to Wiki.js
Modern open source wiki on Node
Wiki.js ranks #3 of 9 in Team wikis, with an Alt Score of 89. It is licensed under AGPL-3.0, free and available on the web. 12 of 12 checklist rows are verified against a public source.
Teams and organizations that want a self-hosted, open-source wiki for collaborative documentation and knowledge bases, ranging from small teams to enterprises needing granular access control.
A modern wiki platform with multiple editors (Markdown with live preview, WYSIWYG, or plain HTML), full version history with diffing and page recovery, and fine-grained page-level permissions by group. It supports built-in or external search (Elasticsearch, Algolia), storage/sync with Git and cloud backends (S3, Azure, Google Cloud), multiple authentication methods, and over 40 languages including RTL.
You self-host Wiki.js via Docker, Kubernetes, or a native install on Linux, macOS, or Windows Server, backed by a database such as PostgreSQL, MySQL, or SQLite. From there, an admin panel manages users, permissions, and storage, while editors create and edit pages that are automatically versioned.
