Rouler - Per-app split tunnelling for Windows
Show HN: Rouler – Steer Windows traffic per app or IP across multiple interfaces
Rouler is a split tunnelling tool for Windows that lets you route each app, IP, or subnet through the network interface of your choice. Run WireGuard, Tailscale, OpenVPN, and your work VPN side by side—no virtual adapters, no system hooks, no interference. A custom Rust driver keeps it fast and lightweight, while a live activity view shows every connection and the rule it matched. Perfect for gamers and privacy-conscious users who want granular control without the bloat.
Like a lot of people, I can't stand software that sits in the background interfering with everything... So Rouler is built on a few rules: interfere as little as possible, everything in the open, and fast.
