🤔 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
