Supernetworks' Secure Programmable Router

What it does

SPR gives every WiFi device its own isolated network automatically. Per-device VLANs, unique passwords, and default-deny firewall policies. Open source, self-hosted, zero cloud dependencies.

SPR (Secure Programmable Router) is an open-source, self-hosted WiFi router platform from Supernetworks, Inc.

  Bor – Open-source policy management for Linux desktopsAug 2026 · getbor.dev · ▲197
