How much RAM does UniFi Network Server need?

Plan on 2–4 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 UniFi Network Server plus your other workloads fit in RAM with room to spare.

Networking

Manage UniFi networking gear from your own server.

Run the UniFi controller yourself to adopt, configure and monitor access points and switches.

Self-hosting the controller keeps your network management data on your own hardware rather than Ubiquiti’s cloud.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Java + MongoDB.
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 UniFi Network Server its own database user with rights only on its own schema.
Reverse-proxy UniFi Network Server 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 UniFi Network Server patched — most self-hosting incidents are unpatched software.
