How much RAM does Wiki.js need?

Plan on 1–2 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Wiki.js plus your other workloads fit in RAM with room to spare.

Productivity

A powerful, modern wiki with Markdown and Git sync.

A feature-rich wiki supporting Markdown, visual editing, multiple auth providers and Git-backed content storage.

Wiki.js is a strong middle ground: more flexible than BookStack, easier than running a raw docs generator, and it can sync to Git.

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.
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 Wiki.js its own database user with rights only on its own schema.
Reverse-proxy Wiki.js 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 Wiki.js patched — most self-hosting incidents are unpatched software.
