Infix — Immutable.Friendly.Secure

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

Our Values

🔒 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.

Why Choose Infix

Hardware Flexibility: Start with a $35 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.

Use Cases

  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!

Technical Details

bitSign - Code Signing

Built on proven open-source foundations: Linux, Buildroot, and sysrepo — for reliability you can trust:

  • Immutable OS: Read-only filesystem, atomic updates, instant rollback
  • YANG Configuration: Industry-standard models with auto-generated tooling
  • Hardware Acceleration: Linux switchdev support for wire-speed packet processing
  • Container Integration: Docker support with flexible network and hardware access
  • Memory Efficient: Runs comfortably on devices with as little as 256 MB RAM
  • Code Signing: Releases are cryptographically signed for integrity verification

Perfect for everything from resource-constrained edge devices to high-throughput network appliances.

With the entire system modeled in YANG, scalability is no longer an issue, be it in development, testing, or end users deploying and monitoring their devices. All knobs and dials are accessible from the CLI (console/SSH), or remotely using the native NETCONF or RESTCONF APIs.
