How Portside transforms dev ports

Before (The Messy Way)

http://localhost:3000

Cluttered port collisions, tab confusion, hard to share.

With Portside (Clean Port 80)

http://admin.localhost

Routes automatically via standard HTTP port 80 proxy.

Native Architecture

How Portside Works Under The Hood

Zero external dependencies. No DNS tampering, no custom root CAs, and no hosts file hacks.

Standard Port 80 Proxy

Binds directly to port 80 on loopback. Incoming Host headers are matched against your registered routes in microseconds with zero memory overhead.

RFC 6761 Compliant

Modern web engines (Chrome, Firefox, Safari) treat all *.localhost subdomains as special local names that resolve straight to 127.0.0.1 without touching DNS.

Multi-Device LAN Routing

mDNS multicast daemon broadcasts your services across local Wi-Fi, allowing Smart TVs, iPhones, and Android tablets to open your dev builds without setup.
