How much RAM does Docmost need?

2 GB is enough for a small team. The Docmost application itself is lightweight (Node.js); PostgreSQL is the main memory consumer. For teams of 10–20 with active concurrent editing, 4 GB is recommended.

Is real-time collaboration actually built in?

Yes. Docmost uses operational transformation so multiple editors can type on the same page simultaneously — no document locking, no manual merging. Changes appear live for all connected users.

Can I embed diagrams and code blocks?

Yes. Docmost has native blocks for Mermaid (flowcharts, sequence diagrams), Draw.io (complex diagrams) and Excalidraw (whiteboard sketches), plus syntax-highlighted code blocks. No extra plugins required.

How does Docmost compare to Wiki.js?

Both are open-source self-hosted wikis. Docmost focuses on real-time collaborative editing (closer to Notion) with a modern block editor. Wiki.js offers more output formats and a Git storage backend. Choose Docmost for collaborative writing; Wiki.js for Markdown-centric or Git-based docs.

Docmost is an open-source collaborative wiki and documentation platform built as a self-hosted alternative to Notion and Confluence. Multiple people can work on the same page simultaneously — no overwrites, no document locking — with changes synced live across all connected editors.

Deployed on a ServOrbit VPS, Docmost gives your team a private knowledge base with nested page trees, full-text search, inline comments, page history and built-in diagramming (Mermaid, Draw.io, Excalidraw). The entire stack runs in three Docker containers — Docmost, PostgreSQL and Redis — from a single Compose file. Your docs stay on your server, subject to your retention policy, with no per-seat pricing or vendor lock-in.

Déployer Docmost sur votre VPS

Guide optimisé pour les VPS Cloud ServOrbit.

01

Provision a VPS

Order a ServOrbit VPS with at least 2 GB RAM (4 GB for teams of 10+) running Ubuntu 22.04. Docmost itself is lightweight — most of the RAM budget goes to PostgreSQL. Open port 3000 or plan a reverse proxy on port 80/443.

02

Generate secrets

SSH into the VPS and run openssl rand -hex 32 to generate APP_SECRET. Choose a strong POSTGRES_PASSWORD. Create /opt/docmost/.env with APP_URL, APP_SECRET, DATABASE_URL (postgresql://docmost:@db/docmost) and REDIS_URL (redis://redis:6379).

03

Deploy with Docker Compose

Create /opt/docmost/docker-compose.yml with three services: docmost (docmost/docmost:latest, port 3000), db (postgres:16-alpine) and redis (redis:7-alpine, --appendonly yes). Then run docker compose up -d. Allow 30 seconds for migrations on first boot.

04

Reverse proxy + SSL

With Caddy: docs.yourdomain.com { reverse_proxy localhost:3000 } — TLS is automatic. With Nginx: proxy_pass http://127.0.0.1:3000 + Certbot. Update APP_URL in .env to your HTTPS domain and restart: docker compose restart docmost.

05

Create your workspace

Open the UI, register the first admin account and name your workspace. Invite teammates from Settings → Members. Pages live in a tree on the left sidebar — start with a home page and grow from there.
