Docmost

Open-source collaborative wiki and documentation software, an alternative to Confluence and Notion.

Alternative to: notion, confluence

Docmost is an open-source, self-hosted collaborative wiki and documentation platform built as an alternative to Confluence and Notion. It supports real-time collaborative editing, diagrams (Draw.io, Excalidraw, and Mermaid), spaces, groups, granular permissions management, comments, page history, and full-text search. Content can include file attachments and embeds from tools like Airtable, Loom, and Miro, with the interface available in 10+ languages.

Docmost Docker Compose example

Self-host Docmost on your own server, homelab, or VPS starting from this Docker Compose example. It runs Docmost in Docker containers using the official docmost/docmost:latest, postgres:18, redis:8 images, with persistent volumes and automatic restarts preconfigured. Review the environment variables and adjust them to your setup, save the file as compose.yml (or docker-compose.yml), and start the stack with docker compose up -d.
