What's included

Six things a video course can't teach you

Reading slides only takes you so far. The lab is where the protocol stops being abstract.

Full Open5GS 5G+4G core

Every NF wired up and ready: AMF · SMF · UPF · AUSF · UDM · UDR · NRF · NSSF · PCF · BSF · SCP · SEPP, plus the 4G NFs (MME · HSS · PCRF · SGW-C · SGW-U).

  • Restart any NF and watch reattach
  • Tail journalctl per-NF
  • Edit YAML config, reload, observe

UERANSIM gNB + UE

A simulated gNB and 3 UEs with configurable IMSI, key, OPC, slice. Trigger registration / deregistration / handover-style flows on demand.

  • UE attach + PDU establishment
  • uesimtun0 interface live
  • Run iperf through the tunnel

Live Grafana — 45 panels

Real-time dashboards: registered UEs, active PDU sessions, RX/TX bytes per NF, P95 latency, error rates, OS metrics. 5-second refresh.

  • NF-by-NF health
  • UPF tunnel throughput
  • SBI HTTP/2 latency P50/P95/P99

NetEm impairments

Inject realistic network conditions on the UPF data path. Test how applications behave when the radio is bad.

  • Latency 0–500 ms
  • Packet loss 0–10%
  • Jitter & reordering

Pre-recorded call flows

Curated PCAP samples (NGAP, NAS-5GS, HTTP/2 SBI) annotated step-by-step. Study the protocol at your pace — no need to capture live.

  • Initial registration walkthrough
  • PDU session establishment
  • Service request + paging

Web terminal — direct shell

Multi-tab in-browser ttyd terminal with 11 preset commands (start UE, ping 8.8.8.8, tail any NF log, journalctl filter).

  • No SSH client to install
  • Persistent across page reloads
  • Sandboxed — your private namespace
Pricing · One simple plan

How it works

Three steps. Under two minutes.

1

Pay $100 (or ₹9,400)

Click the button, choose UPI / card / Net Banking. Razorpay handles it. You get an instant invoice by email.

2

Land on the lab

You're auto-redirected to your private lab page. Bookmark it — same URL works for the next 30 days.

3

Break stuff. Learn fast.

Open the web terminal, attach a UE, watch Grafana spike. Restart the SMF mid-session and see what happens. Read the call-flow PCAPs while it stabilises.

Questions

Things you'll want to know

30 days from the moment payment clears. No auto-renew, no card stored. When you're close to expiry, we'll send you a reminder email — pay $100 again to extend, or just walk away with no friction.
Yes. Each tenant gets isolated NF state, isolated UE identities, and isolated traffic. You can systemctl restart any NF without affecting anyone else. The terminal sessions are namespaced. Grafana shows your tenant's metrics only.
Honest answer: we used to offer it, and a single forgotten capture filled a 200 GB disk in 4 days. We removed it entirely. In its place, you get curated, annotated PCAP samples for the call flows that matter (registration, PDU establishment, service request, handover-style). They cover what 95% of engineers actually need without the operational risk.
Not in the standard plan — networking to external endpoints needs explicit IP allow-listing on our end. If you're trying to connect a real Quectel / Sierra modem or an external srsRAN gNB, email [email protected] and we'll set up custom routing for an extra $50/month.
7-day refund, no questions asked, as long as you've used less than 30% of your 30-day window. Email [email protected] with your order ID — refund hits your card / UPI in 5–7 working days.
Yes. 5+ seats get 25% off. 20+ seats get a private isolated lab with custom slicing config and a dedicated Grafana. Email [email protected] with your team size — we'll send a quote within 24 hours.
That's the whole point. Restart any NF, edit YAML to invalid values, kill processes, drop the UE link — your tenant gets reset to clean state on demand from the dashboard. You cannot affect other users. You cannot affect anything outside your namespace. Worst case: hit the "Reset lab" button.
