Deploy your mobile network core in minutes.

Rapid5GS turns a stock Ubuntu 24.04 LTS box into a production-ready Open5GS LTE/5G packet core. One command. Free and open source, GPL v3. Written by WISP operators who got tired of six-figure core quotes.

Run this on Ubuntu 24.04 LTS:
$ git clone https://github.com/joshualambert/rapid5gs.git && cd rapid5gs && chmod +x install.sh && sudo ./install.sh

// what you get

Everything between "blank server" and "attached UEs"

Two scripts. That's the whole trick. One builds your core, one runs it, and neither asks you to learn a container orchestrator first.

install.sh

The installer that does the annoying parts so you don't have to. Point it at a fresh Ubuntu box, pick from a numbered menu, and it gets to work:

  • Dependency installation and configuration
  • Network interface setup and routing rules
  • Database initialization
  • Web interface deployment
  • System services and health checks

About twenty minutes later you have a running core and a web UI. The weekend you'd budgeted for reading Open5GS docs? Keep it. Go climb a tower or something.

Rapid5GS installation menu

control.sh

Your whole network, one menu deep. When a customer calls at 2am, you shouldn't have to remember which log lives in which directory. Everything you actually check on a live core is right here:

  • Real-time EPC throughput monitor
  • eNB status: see every connected base station
  • UE status: see every attached subscriber device
  • Live MME and SMF logs for troubleshooting

It's the difference between "let me SSH in and poke around" and "yeah, I'm already looking at it."

// requirements

What you need

  • Ubuntu 24.04 LTS
  • Root access (sudo)
  • 4GB+ RAM
  • 20GB+ free disk
  • Two physical network interfaces

That's it. People run this core on used mini PCs that cost less than dinner for four.

Radios and CPE we've verified

UEs

Any standards-compliant 4G/5G radio should work. The list above is what we've personally put in the field.

Rapid5GS Pro: the same core, with a real GUI

The open source version runs in a terminal, and plenty of operators never need more. Pro adds a full web GUI on top of the same battle-tested core, plus a performance stack built for networks that have outgrown a single box. Development of the Pro features is led by Michael Halls at Nimbus Solutions, the same team that backs it in production.

  • Full web GUI: subscribers, radio status, and live stats in a browser instead of an SSH session
  • Network optimization stack: multiple UPFs and SMFs scaled out and playing nicely together, with Linux tuning for maximum throughput
  • Real routing, not NAT: the open source core NATs everything behind the box. Pro integrates the core into your network, so every device is directly addressable across multiple APNs, including public IPs for customers if you have the allocations
  • 8 hours of expert support from our partner Nimbus Solutions
  • Available now and shipping. This isn't a pre-order.
  • Every sale funds development of the open source project
  • And did we mention the GUI?

Core's done. Now you need radios.

We refurbish, test, and sell the same CBRS hardware we recommend above, through our shop at The Edge Mile. Both options connect to Rapid5GS out of the box.
