free5GC is an open-source implementation of the 5G mobile core network (5GC) compliant with 3GPP Release 15/17, developed as a Linux Foundation project in Go. It provides all core network functions (AMF, SMF, UPF, NRF, UDM, UDR, AUSF, PCF, NSSF, N3IWF) with a service-based architecture and supports Docker and Kubernetes deployments.

Use cases

• run a private 5G core network for research
• test 5G UE registration and PDU sessions in a lab
• deploy a 5G core on Kubernetes for cloud-native experiments
• study 3GPP R15/R17 service-based architecture with real code
• build a campus or industrial private 5G network
• simulate 5G core network functions for development

When to choose

• you need an open-source, standards-compliant 5G core for research, testing, or private networks
• you want containerized/Kubernetes deployment of 5GC network functions
• you need to experiment with or extend 3GPP R15+ core network functions in Go

When to avoid

• you need a carrier-grade, certified production 5G core with vendor support
• you need 4G/LTE EPC or 2G/3G core functionality
• you lack Linux networking expertise (UPF requires kernel/GTP setup)
