Open5GS is an open-source C-language implementation of the 5G Core (5GC) and Evolved Packet Core (EPC), the core network of LTE and NR mobile networks per 3GPP Release-19. It lets operators, researchers, and hobbyists run their own 4G/5G mobile core network on commodity hardware.
Use cases
- set up a private 5G SA core network for testing
- run an LTE/EPC core for a private mobile network
- simulate a 5G core with UERANSIM for research
- deploy VoLTE with IMS and Kamailio
- test 5G roaming with SEPP in a lab
- load test and benchmark UPF performance
- deploy a cloud-native 5G core on Kubernetes
When to choose
- you need a self-hosted 4G/5G core network implementation
- you are building a private LTE or NR network for lab, research, or deployment
- you want an open-source 3GPP Release-19 compliant core with active community support
When to avoid
- you need a production carrier-grade core with vendor support and commercial licensing
- you only need a radio access network simulator without a core
- you want a simple network tool rather than a full telecom core system
