🤔 Why 9Router?

Stop wasting money and hitting limits:

• ❌ Subscription quota expires unused every month
• ❌ Rate limits stop you mid-coding
• ❌ Expensive APIs ($20-50/month per provider)
• ❌ Manual switching between providers

9Router solves this:

• ✅ 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, Gemini CLI, Cursor, Cline, any CLI tool

🔀 Token Rotate — Bypass Quota Limits Automatically

The headline feature that sets n9router apart.

If you use Antigravity, you know the pain: one account hits quota mid-session and everything stops. Token Rotate solves this at the proxy level — completely transparent to your CLI tool.

Your CLI tool  →  n9router MITM proxy  →  Antigravity Account A
                                       ↓ (429 / quota hit)
                                       →  Antigravity Account B
                                       ↓ (quota hit)
                                       →  Antigravity Account C
                                       ↓ (all rotated, cooldown respected)
                                       → waits + retries automatically

Two rotation strategies:

| Strategy | Behaviour | Best For | |----------|-----------|----------| | Round-Robin | Distribute every request evenly across all accounts | Spreading load, many accounts | | Sticky | Stay on one account until its quota is exhausted, then rotate | Fewer accounts, maximize each one fully |

How it works under the hood:

• When the MITM proxy receives a 429 / quota error, it automatically retries with the next account
• Per-account, per-model cooldown timers are parsed from error responses and respected
• Tokens nearing expiry trigger a background refresh — zero interruptions
• Live pool status dashboard: quota bars, cooldown countdowns, per-account health

Enable it in 3 steps:

1. Dashboard → CLI Tools → MITM Server → Start
2. Dashboard → CLI Tools → DNS Redirect → Enable
3. Dashboard → CLI Tools → Token Swap Pool → Toggle ON

Add as many Antigravity accounts as you want — each one extends your effective quota linearly.

Note: Token Swap Pool (Mode B) and MITM Model Routing (Mode A) are mutually exclusive. Enabling Token Swap Pool bypasses the alias pass-through, shown as "Bypassed" in the UI.

💡 Key Features

| Feature | What It Does | Why It Matters | |---------|--------------|----------------| | 🔀 Token Rotate | MITM-level Antigravity account rotation (round-robin or sticky) | Bypass quota limits across accounts transparently | | 🎯 Smart 3-Tier Fallback | Auto-route: Subscription → Cheap → Free | Never stop coding, zero downtime | | 📊 Real-Time Quota Tracking | Live token count + reset countdown | Maximize subscription value | | 🔄 Format Translation | OpenAI ↔ Claude ↔ Gemini seamless | Works with any CLI tool | | 👥 Multi-Account Support | Multiple accounts per provider | Load balancing + redundancy | | 🔄 Auto Token Refresh | OAuth tokens refresh automatically | No manual re-login needed | | 🎨 Custom Combos | Create unlimited model combinations | Tailor fallback to your needs | | 📝 Request Logging | Debug mode with full request/response logs | Troubleshoot issues easily | | 💾 Cloud Sync | Sync config across devices | Same setup everywhere | | 📊 Usage Analytics | Track tokens, cost, trends over time | Optimize spending | | 🌐 Deploy Anywhere | Localhost, VPS, Docker, Cloudflare Workers | Flexible deployment options |

🎯 Smart 3-Tier Fallback

Create combos with automatic fallback:

Combo: "my-coding-stack"
  1. cc/claude-opus-4-6        (your subscription)
  2. glm/glm-4.7               (cheap backup, $0.6/1M)
  3. if/kimi-k2-thinking       (free fallback)

→ Auto switches when quota runs out or errors occur

📊 Real-Time Quota Tracking

• Token consumption per provider
• Reset countdown (5-hour, daily, weekly)
• Cost estimation for paid tiers
• Monthly spending reports

🔄 Format Translation

Seamless translation between formats:

• OpenAI ↔ Claude ↔ Gemini ↔ OpenAI Responses
• Your CLI tool sends OpenAI format → 9Router translates → Provider receives native format
• Works with any tool that supports custom OpenAI endpoints

👥 Multi-Account Support

• Add multiple accounts per provider
• Auto round-robin or priority-based routing
• Fallback to next account when one hits quota

🔄 Auto Token Refresh

• OAuth tokens automatically refresh before expiration
• No manual re-authentication needed
• Seamless experience across all providers

🔀 Token Swap Pool (Antigravity MITM)

Transparently rotate between multiple Antigravity accounts at the MITM proxy level — no changes needed in your CLI tool.

Two rotation strategies:

| Strategy | Behaviour | |----------|-----------| | Round-Robin | Distribute requests evenly across all accounts | | Sticky | Stay on one account until its model quota is exhausted, then rotate |

How it works:

• When the MITM proxy receives a 429 / quota error from Antigravity, it automatically retries with the next available account
• Per-account and per-model cooldowns are parsed from the error response and respected
• Tokens near expiry trigger a fire-and-forget refresh in the background
• Pool status, live quota bars, and a strategy selector are visible on the dashboard Token Swap Pool card

Enable it:

Dashboard → CLI Tools → Token Swap Pool → Toggle ON
Prerequisites: MITM Server running + DNS redirected

Mode A vs Mode B: Model Routing (MITM alias) and Token Rotation are mutually exclusive. When Token Swap Pool is enabled (Mode B), the MITM alias pass-through is bypassed and shown as "Bypassed" in the UI.

🎨 Custom Combos

• Create unlimited model combinations
• Mix subscription, cheap, and free tiers
• Name your combos for easy access
• Share combos across devices with Cloud Sync

📝 Request Logging

• Enable debug mode for full request/response logs
• Track API calls, headers, and payloads
• Troubleshoot integration issues
• Export logs for analysis

💾 Cloud Sync

• Sync providers, combos, and settings across devices
• Automatic background sync
• Secure encrypted storage
• Access your setup from anywhere

Cloud Runtime Notes

• Prefer server-side cloud variables in production:
  • BASE_URL (internal callback URL used by sync scheduler)
  • CLOUD_URL (cloud sync endpoint base)
• NEXT_PUBLIC_BASE_URL and NEXT_PUBLIC_CLOUD_URL are still supported for compatibility/UI, but server runtime now prioritizes BASE_URL/CLOUD_URL.
• Cloud sync requests now use timeout + fail-fast behavior to avoid UI hanging when cloud DNS/network is unavailable.

📊 Usage Analytics

• Track token usage per provider and model
• Cost estimation and spending trends
• Monthly reports and insights
• Optimize your AI spending

💡 IMPORTANT - Understanding Dashboard Costs:

The "cost" displayed in Usage Analytics is for tracking and comparison purposes only. 9Router itself never charges you anything. You only pay providers directly (if using paid services).

Example: If your dashboard shows "$290 total cost" while using iFlow models, this represents what you would have paid using paid APIs directly. Your actual cost = $0 (iFlow is free unlimited).

Think of it as a "savings tracker" showing how much you're saving by using free models or routing through 9Router!

🌐 Deploy Anywhere

• 💻 Localhost - Default, works offline
• ☁️ VPS/Cloud - Share across devices
• 🐳 Docker - One-command deployment
• 🚀 Cloudflare Workers - Global edge network

📊 Understanding 9Router Costs & Billing

9Router Billing Reality:

✅ 9Router software = FREE forever (open source, never charges)
✅ Dashboard "costs" = Display/tracking only (not actual bills)
✅ You pay providers directly (subscriptions or API fees)
✅ FREE providers stay FREE (iFlow, Kiro, Qwen = $0 unlimited)
❌ 9Router never sends invoices or charges your card

How Cost Display Works:

The dashboard shows estimated costs as if you were using paid APIs directly. This is not billing - it's a comparison tool to show your savings.

Example Scenario:

Dashboard Display:
• Total Requests: 1,662
• Total Tokens: 47M
• Display Cost: $290

Reality Check:
• Provider: iFlow (FREE unlimited)
• Actual Payment: $0.00
• What $290 Means: Amount you SAVED by using free models!

Payment Rules:

• Subscription providers (Claude Code, Codex): Pay them directly via their websites
• Cheap providers (GLM, MiniMax): Pay them directly, 9Router just routes
• FREE providers (iFlow, Kiro, Qwen): Genuinely free forever, no hidden charges
• 9Router: Never charges anything, ever

❓ Frequently Asked Questions

The dashboard tracks your token usage and displays estimated costs as if you were using paid APIs directly. This is not actual billing - it's a reference to show how much you're saving by using free models or existing subscriptions through 9Router.

Example:

• Dashboard shows: "$290 total cost"
• Reality: You're using iFlow (FREE unlimited)
• Your actual cost: $0.00
• What $290 means: Amount you saved by using free models instead of paid APIs!

The cost display is a "savings tracker" to help you understand your usage patterns and optimization opportunities.

No. 9Router is free, open-source software that runs on your own computer. It never charges you anything.

You only pay:

• ✅ Subscription providers (Claude Code $20/mo, Codex $20-200/mo) → Pay them directly on their websites
• ✅ Cheap providers (GLM, MiniMax) → Pay them directly, 9Router just routes your requests
• ❌ 9Router itself → Never charges anything, ever

9Router is a local proxy/router. It doesn't have your credit card, can't send invoices, and has no billing system. It's completely free software.

Yes! Providers marked as FREE (iFlow, Kiro, Qwen) are genuinely unlimited with no hidden charges.

These are free services offered by those respective companies:

• iFlow: Free unlimited access to 8+ models via OAuth
• Kiro: Free unlimited Claude models via AWS Builder ID
• Qwen: Free unlimited access to Qwen models via device auth

9Router just routes your requests to them - there's no "catch" or future billing. They're truly free services, and 9Router makes them easy to use with fallback support.

Note: Some subscription providers (Antigravity, GitHub Copilot) may have free preview periods that could become paid later, but this would be clearly announced by those providers, not 9Router.

Free-First Strategy:

1. Start with 100% free combo:

   1. gc/gemini-3-flash (180K/month free from Google)
   2. if/kimi-k2-thinking (unlimited free from iFlow)
   3. qw/qwen3-coder-plus (unlimited free from Qwen)

   Cost: $0/month

2. Add cheap backup only if you need it:

   4. glm/glm-4.7 ($0.6/1M tokens)

   Additional cost: Only pay for what you actually use

3. Use subscription providers last:

   • Only if you already have them
   • 9Router helps maximize their value through quota tracking

Result: Most users can operate at $0/month using only free tiers!

9Router's smart fallback prevents surprise charges:

Scenario: You're on a coding sprint and blow through your quotas

Without 9Router:

• ❌ Hit rate limit → Work stops → Frustration
• ❌ Or: Accidentally rack up huge API bills

With 9Router:

• ✅ Subscription hits limit → Auto-fallback to cheap tier
• ✅ Cheap tier gets expensive → Auto-fallback to free tier
• ✅ Never stop coding → Predictable costs

You're in control: Set spending limits per provider in dashboard, and 9Router respects them.

🐛 Troubleshooting

"Language model did not provide messages"

• Provider quota exhausted → Check dashboard quota tracker
• Solution: Use combo fallback or switch to cheaper tier

Rate limiting

• Subscription quota out → Fallback to GLM/MiniMax
• Add combo: cc/claude-opus-4-6 → glm/glm-4.7 → if/kimi-k2-thinking

OAuth token expired

• Auto-refreshed by 9Router
• If issues persist: Dashboard → Provider → Reconnect

High costs

• Check usage stats in Dashboard
• Switch primary model to GLM/MiniMax
• Use free tier (Gemini CLI, iFlow) for non-critical tasks

Dashboard opens on wrong port

• Set PORT=20128 and NEXT_PUBLIC_BASE_URL=http://localhost:20128

First login not working

• Check INITIAL_PASSWORD in .env
• If unset, fallback password is 123456

No request logs under logs/

• Set ENABLE_REQUEST_LOGS=true

Antigravity quota exhausted / Token Swap Pool not rotating

• Ensure MITM Server and DNS redirect are active (both prerequisites shown in the Token Swap Pool card)
• Add multiple Antigravity accounts: Dashboard → Providers → Connect Antigravity (repeat for each account)
• Toggle Token Swap Pool ON in Dashboard → CLI Tools → Token Swap Pool
• Check the pool card for accounts marked ⛔ bad account (auth expired) and reconnect them
• If using sticky strategy and all accounts are on cooldown for the same model, switch to round-robin temporarily
