Before you commit, here's exactly what to expect, what your server needs to run the relay, and what we'll need from you to get you licensed and connected. No surprises — read it all first.
A straightforward path — most of it is just getting your server and license in order.
Share your company details, a technical contact, and the domain you'll run the relay on. Want to see it live first? Request a demo or an evaluation at any point.
Pick the tier that fits — personal, business, or enterprise. We'll confirm your term and send everything you need to complete licensing.
Within 24 hours of confirmed payment, we email your download link and detailed, step-by-step setup instructions to your technical contact.
Follow the guide on your own Linux server. Prefer a hand? Optional paid onboarding puts our team on the setup call with you.
Your clients and hosts download or install straight from your relay server, and your team is in control — all on infrastructure you own.
NxLink runs as a single, self-contained service on one Linux box — no cloud database, no sprawl of extra services to manage.
| Operating system | Linux — Debian / Ubuntu-style (systemd + Apache2) |
| Runtime | Python 3.12 |
| Web / proxy | Reverse proxy on port 443 (Apache, nginx, Caddy…) — TLS for mobile / web clients |
| Database | SQLite — file-based & bundled, no separate DB server |
| CPU / memory | ~1–2 vCPU, 2 GB RAM is typically plenty (service caps at 1 GB) |
| Open ports | 9600/TCP · 9601/UDP · 9680/TCP · 443/TCP |
| TLS certificate | Required — issued for your domain; used by the relay (9600) and the 443 endpoint |
| Session encryption | End-to-end encrypted between client and host — X25519 (ECDH) key exchange with HKDF-SHA256, AES-256-GCM per channel |
| Domain | One subdomain pointed at the server (e.g. nxlink.yourcompany.com) |
Relay, admin panel, and database all run on a single server. Nothing to wire together.
A roughly 1 GB memory footprint — comfortable on a modest, inexpensive VPS.
9601/UDP streams the video frames. If it's blocked, sessions fall back to TCP — but open UDP gives the smoothest experience.
The relay is just a small Linux service — put it wherever suits your security and budget.
Keep it entirely inside your own network on hardware you physically control.
Run it in an AWS, Azure, GCP, or other cloud account that belongs to you.
An inexpensive VPS is more than enough for the relay's lightweight footprint.
Choose the tier that matches your team. Pricing is tailored to your size and term — we'll share it on request.
For individuals and home labs.
For in-house IT and growing help desks.
For large fleets and managed-service providers.

Exact host and session limits per tier are set with you when you license — ask us for current figures. Not sure which fits? Request a live demo or an evaluation.
A short list — gathering it up front means we can get you licensed and set up without back-and-forth.
So we can issue your license and invoice correctly.
The person we'll email setup instructions to and coordinate any onboarding with.
The subdomain your server will use — your license is keyed to it.
The tier and length that fits your team. Unsure? We'll talk it through.
Start your request and we'll take it from there. Once sign-up and payment go live, this is where you'll complete licensing — for now, it opens the conversation, and you can ask for a demo at any time.
Sign-up & payment are coming soon. After confirmed payment, we email your download link and setup guide within 24 hours.
