Docmost

Self-hosted, enterprise-ready wiki and documentation platform with real-time collaboration and AI capabilities.

Overview

Docmost is an open-source, self-hosted wiki and documentation platform designed as an alternative to Confluence and Notion. It enables teams to collaborate in real-time on pages, organize knowledge through spaces, and manage content with granular permissions—all while maintaining complete control over data and infrastructure.

The platform supports real-time collaborative editing, structured databases (Bases with table and Kanban views), built-in diagramming tools (Draw.io, Excalidraw, Mermaid), and AI-powered features including semantic search and chat. It can be deployed on-premises or in air-gapped environments, making it suitable for organizations with strict compliance requirements like ITAR, FedRAMP, and GDPR.

Docmost offers a free Community edition with core features, plus Business and Enterprise tiers that add SSO, advanced AI, API access, audit logs, and page verification workflows.
