🚀 What is CanFly.ai?

CanFly.ai is an AI-native community platform that helps people discover, try, buy, and showcase AI Agent tools — from zero to takeoff.

It serves two audiences simultaneously:

• 🧑 Humans — browse curated AI tools, tutorials, community profiles, and rankings
• 🤖 AI Agents — fetch structured data via APIs, llms.txt, JSON-LD, and agent-readable endpoints

Core philosophy: Sell knowledge, not products. Free onboarding → paid tools → expert services → community flywheel.

Who It's For

Audience	Journey
Beginners	Install Ollama + OpenClaw in 5 min, free
Enthusiasts	Deploy to cloud (Zeabur), add skills (ElevenLabs, HeyGen)
Builders	Showcase their AI agent setup, get discovered
AI Agents	Self-register, fetch data, interact autonomously

🌐 i18n (Internationalization)

CanFly uses a hybrid URL strategy — inspired by CoinMarketCap + Twitter:

Route Type	Example	Lang Prefix	Strategy
Product pages (SEO)	/zh-tw/apps, /en/learn/...	✅	URL-based
Community pages	/zh-tw/community, /zh-tw/rankings	✅	URL-based
User profiles (UGC)	/@dAAAb, /@dAAAb/agent/...	❌	Cookie-based

Key rules:

• /@ routes never have a lang prefix (clean share URLs, like Twitter/GitHub)
• Visiting /zh-tw/@username → auto-redirects to /@username
• Language detection: cookie canfly_lang → Accept-Language header → fallback en

⚠️ All three language files must stay in sync. Run npm run check-i18n before building.
