Why Nylon?

Nylon is a self-healing WireGuard mesh that routes around failures. If a link goes down, nylon reroutes traffic through the next-best path in seconds. No manual intervention, no central coordination servers.

Under the hood, nylon implements the Babel routing protocol (RFC 8966) on top of a modified wireguard-go, using measured latency as the routing metric.

Main Features

• Multi-hop Routing: Traffic flows through the lowest-latency path across your mesh. Unlike Tailscale, Nebula, or ZeroTier, nodes don’t need to be directly reachable from each other. Nylon forwards through intermediate hops automatically.
• No Coordination Server: No SaaS dependency, no single control-plane. Nodes exchange routes directly over the same WireGuard tunnel that carries your data.
• Single Binary, Single Port: One statically-linked binary, one UDP port (57175), one YAML config. That’s it.
• WireGuard Client Compatibility: Connect stock WireGuard clients (iOS, Android, Windows) to the mesh with zero extra software. Mobile clients roam between gateways seamlessly.
• Native WireGuard Speeds: Data-plane runs entirely in wireguard-go (polyamide), capable of 10+ Gbps throughput.

Encryption Model

Nylon uses WireGuard’s encryption hop-by-hop, not end-to-end. Each link between adjacent nodes is encrypted, but intermediate nodes decrypt and re-encrypt forwarded traffic. This is the same model as DIY WireGuard+Babel setups. If you need end-to-end encryption between every pair of nodes, Tailscale or Nebula may be a better fit.

When to use nylon

• Distributed edge nodes: Build low-latency anycast networks for geographically distributed services that adapt to changing conditions.
• Home lab networking: Connect home devices, servers, and cloud resources into a single resilient network.
• Sovereign networks: Fully independent mesh that works in isolated or air-gapped environments. No “phone-home” requirement.
• Optimized routing: Automatically use the lowest-latency path without manual configuration changes.

Nylon vs. DIY WireGuard+Babel

If you’ve ever tried to build a dynamic network using WireGuard + Babel (or BGP), you know how powerful it can be, but also how painful it is to maintain.

The typical setup involves running separate WireGuard interfaces for every peering arrangement, along with a routing daemon to manage dynamic routing. This gives you a powerful, self-healing network, but it’s cumbersome to set up and maintain.

Nylon is that powerful DIY stack refined into a single, opinionated binary. It automates the tedious parts, giving you the resilience of a professional routing setup with the ease of a modern VPN.
