🤔 Why 9Router?

Stop wasting money, tokens and hitting limits:

• ❌ Subscription quota expires unused every month
• ❌ Rate limits stop you mid-coding
• ❌ Tool outputs (git diff, grep, ls...) burn tokens fast
• ❌ Expensive APIs ($20-50/month per provider)
• ❌ Manual switching between providers

9Router solves this:

• ✅ RTK Token Saver - Auto-compress tool_result content, save 20-40% tokens per request
• ✅ Maximize subscriptions - Track quota, use every bit before reset
• ✅ Auto fallback - Subscription → Cheap → Free, zero downtime
• ✅ Multi-account - Round-robin between accounts per provider
• ✅ Universal - Works with Claude Code, Codex, Cursor, Cline, any CLI tool
