Cilium vs Faucet
Both stand on software-defined networking software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxSelf-hosted
Cilium brings networking, policy, security, and observability features together for Linux workload environments. Check kernel and scale requirements before choosing an installation path.
Visit Cilium Free plan LinuxSelf-hosted
Choose Faucet if you operate production networks with supported OpenFlow switches and want a free, self-hosted controller with routing, policy, and monitoring capabilities. Look elsewhere if your hardware depends on vendor-specific pipelines such as Broadcom OFDPA, or if you need RADIUS accounting or multiple RADIUS servers.
