What is it?
Alexandrie is a self-hosted wiki and knowledge management platform for teams and individuals, positioned as an alternative to Notion, Confluence and Obsidian. It organizes content into teams, workspaces, categories and nested documents, with a five-level access model from None to Owner applied per node or workspace.
The editor is built on CodeMirror 6 and extends Markdown with LaTeX, custom containers, interactive checkboxes, diagrams, speech-to-text dictation and a reusable snippet manager. Full-text search, a Ctrl+K command center and built-in Kanban boards sit alongside the documentation.
The app ships as a PWA that works offline and syncs when reconnected. Deployment uses Docker Compose, with OIDC SSO support, S3-compatible object storage (such as MinIO, Garage or AWS), ZIP import and export, and full-system backup and restore.
