🤔 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

⚡ Quick Start

1. Install globally:

npm install -g 9router
9router

🎉 Dashboard opens at http://localhost:20128

2. Connect a FREE provider (no signup needed):

Dashboard → Providers → Connect Claude Code or Antigravity → OAuth login → Done!

3. Use in your CLI tool:

Claude Code/Codex/Gemini CLI/OpenClaw/Cursor/Cline Settings:
  Endpoint: http://localhost:20128/v1
  API Key: [copy from dashboard]
  Model: if/kimi-k2-thinking

That's it! Start coding with FREE AI models.

Alternative: run from source (this repository):

This repository package is private (9router-app), so source/Docker execution is the expected local development path.

cp .env.example .env
npm install
PORT=20128 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run dev

Production mode:

npm run build
PORT=20128 HOSTNAME=0.0.0.0 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run start

Default URLs:

Dashboard: http://localhost:20128/dashboard
OpenAI-compatible API: http://localhost:20128/v1

📖 Feature Details

🎯 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

🎨 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

📊 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

🎯 Use Cases

Case 1: "I have Claude Pro subscription"

Problem: Quota expires unused, rate limits during heavy coding

Solution:

Combo: "maximize-claude"
  1. cc/claude-opus-4-6        (use subscription fully)
  2. glm/glm-4.7               (cheap backup when quota out)
  3. if/kimi-k2-thinking       (free emergency fallback)

Monthly cost: $20 (subscription) + ~$5 (backup) = $25 total
vs. $20 + hitting limits = frustration

Case 2: "I want zero cost"

Problem: Can't afford subscriptions, need reliable AI coding

Solution:

Combo: "free-forever"
  1. gc/gemini-3-flash         (180K free/month)
  2. if/kimi-k2-thinking       (unlimited free)
  3. qw/qwen3-coder-plus       (unlimited free)

Monthly cost: $0
Quality: Production-ready models

Case 3: "I need 24/7 coding, no interruptions"

Problem: Deadlines, can't afford downtime

Solution:

Combo: "always-on"
  1. cc/claude-opus-4-6        (best quality)
  2. cx/gpt-5.2-codex          (second subscription)
  3. glm/glm-4.7               (cheap, resets daily)
  4. minimax/MiniMax-M2.1      (cheapest, 5h reset)
  5. if/kimi-k2-thinking       (free unlimited)

Result: 5 layers of fallback = zero downtime
Monthly cost: $20-200 (subscriptions) + $10-20 (backup)

Case 4: "I want FREE AI in OpenClaw"

Problem: Need AI assistant in messaging apps (WhatsApp, Telegram, Slack...), completely free

Solution:

Combo: "openclaw-free"
  1. if/glm-4.7                (unlimited free)
  2. if/minimax-m2.1           (unlimited free)
  3. if/kimi-k2-thinking       (unlimited free)

Monthly cost: $0
Access via: WhatsApp, Telegram, Slack, Discord, iMessage, Signal...

❓ Frequently Asked Questions

📊 Why does my dashboard show high costs?

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.

💳 Will I be charged by 9Router?

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.

🆓 Are FREE providers really unlimited?

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.

💰 How do I minimize my actual AI costs?

Free-First Strategy:

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

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
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!

📈 What if my usage suddenly spikes?

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.

      }
    }
  },
  "models": {
    "providers": {
      "9router": {
        "baseUrl": "http://127.0.0.1:20128/v1",
        "apiKey": "sk_9router",
        "api": "openai-completions",
        "models": [

🐛 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
