Route Servers.
Without The Sprawl.

A fast, lightweight Go gateway and reverse proxy. Route domains, serve SPAs, and automate Let's Encrypt TLS in one human-readable Runtime file.

Core Superpowers

Engineered For Clean Server Routing

Everything you need from a modern reverse proxy without the enterprise bloat.

Ergonomic Syntax

Zero-Sprawl Gateway

Declare domain reverse proxies, port listeners, and static folders in one intuitive Runtime file. Replace complex multi-file configurations with 3 clean lines.

api.example.com {
    proxy localhost:3000
}

Automated TLS

Zero-Config Let's Encrypt

Secure by default. Automatically provisions, verifies, and renews ACME TLS/SSL certificates on port 443 for all your domain routes without Certbot.

:443 HTTPS & HTTP/2
Auto-renew 30 days before expiry

systemd Native

Hot Auto-Reload on Save

Edit /etc/terror/Runtime in vim or nano and save. The integrated systemd terror.path immediately applies routing and listener changes with zero downtime.

sudo vim /etc/terror/Runtime
# Saved -> terror.service auto reloads

Instant Observability

Deep CLI Health Diagnostics

Run `terror status` to instantly diagnose DNS resolution, port listeners, TLS certificate validity, static root paths, and upstream backend responsiveness.

terror status
-> ok DNS, Port, SSL, Upstream

Single Go Binary

Zero Dependencies

No Node.js, Python, or OpenSSL runtime dependencies. Under 15MB binary with minimal memory footprint (<20MB RAM) for ultra-fast TTFB response times.

Linux amd64 & arm64
Pure Go compiled binary

SPA Friendly

Static & SPA Fallback Server

High-speed static asset delivery with built-in client-side routing fallback for React, Vue, Svelte, and Vite apps. Never see 404 on browser reload again.

app.example.com {
    root /var/www/dist
    file_server
}
