Productivity

A fast, modern team knowledge base.

A clean, searchable wiki with a great editor, permissions and integrations, for team documentation and knowledge sharing.

Outline is the nicest open-source team wiki to self-host, with the polish of a paid product and your data staying put.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Node.js + PostgreSQL + Redis + S3.
3
Deploy the application
Follow the project’s official install guide for your distribution.
4
Enable HTTPS
Serve it on your own domain behind a reverse proxy with a certificate.
5
Back it up
Schedule a database dump plus a copy of any uploaded files to an off-box location.

Give Outline its own database user with rights only on its own schema.
Reverse-proxy Outline and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep Outline patched — most self-hosting incidents are unpatched software.
