Nah.pet – "Rewriting paths with bad energy" ✨
Open-source URL shortener with custom domains and analytics.

📚 OpenAPI Documentation

• ✂️ URL Shortening with custom slugs
• 🔐 Password protection for sensitive links
• ⏰ Automatic link expiration
• 📊 Detailed analytics (clicks, geolocation, browsers)
• 🌐 Custom domains with complete isolation
• 👥 Admin system with manual approval
• 🔑 REST API with API key authentication
• 🌍 Multilingual interface

Managed with Paraglide JS and Weblate for type-safety.

The cat. prefix bypasses CORS restrictions from Cloudflare and other CDNs by using a dedicated subdomain.

1. Domain verification:

   • DNS: TXT record with token
   • File: /.well-known/nah-pet-verification.txt

2. CNAME configuration:

   Type: CNAME
   Name: cat.example.com
   Value: cat.nah.pet
   TTL: 300
   

3. Redirection:

   https://cat.example.com/abc123 → CNAME → cat.nah.pet → nah.pet
   

Each custom domain is fully isolated—no access to system routes (/admin, /login, etc.).
