Infix — Immutable.Friendly.Secure

Turn any ARM or x86 device into a powerful, manageable network appliance in minutes. From 35ドル Raspberry Pi boards to enterprise switches — deploy routers, IoT gateways, edge devices, or custom network solutions that just work.

🔒 Immutable
Your system never breaks. Read-only filesystem with atomic upgrades means no configuration drift, no corrupted updates, and instant rollback if something goes wrong. Deploy once, trust forever.

🤝 Friendly
Actually easy to use. Auto-generated CLI from standard YANG models comes with built-in help for every command — just hit ? or TAB for context-aware assistance. Familiar NETCONF/RESTCONF APIs and comprehensive documentation mean you're never stuck. Whether you're learning networking or managing enterprise infrastructure.

🛡️ Secure
Built with security as a foundation, not an afterthought. Minimal attack surface, separation between system and data, and container isolation. Sleep better knowing your infrastructure is protected.

Hardware Flexibility: Start with a 35ドル Raspberry Pi, scale to enterprise switching hardware. Same OS, same tools, same reliability.

Standards-Based: Built around YANG models and IETF standards. Learn once, use everywhere - no vendor lock-in.

Container Ready: Run your applications alongside networking functions. GPIO access, dedicated Ethernet ports, custom protocols — your device, your rules.

1. Home Labs & Hobbyists:
   Transform a Raspberry Pi into a full-featured router with WiFi
2. IoT & Edge Computing:
   Bridge devices to the cloud with reliable, updatable gateways
3. Small Business Networks:
   Enterprise-grade features without the complexity or cost
4. Developers & Makers:
   Test networking concepts, prototype IoT solutions, or build custom appliances
5. Network Professionals:
   Consistent tooling from development to production deployment.
   How about a digital twin using raw Qemu or GNS3!
