**n9router** is a self-hosted AI routing gateway and OpenAI-compatible Docker proxy for Claude Code, Cursor, Antigravity, Copilot, Codex, Gemini CLI, OpenCode, Cline, OpenClaw, and 40+ AI providers. Run it locally, on a VPS, or with the public Docker Hub image to get model fallback, quota tracking, token savings, format translation, and multi-account routing.

---

## 🤔 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

## 🔀 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

<div align="center">
  <img src="./images/token-rotate-under-the-hood.png" alt="Token Rotate — How It Works Under the Hood" width="700"/>
</div>

### 🚀 Step-by-Step Setup

<div align="center">
  <img src="./images/token-rotate-setup-guide.png" alt="Token Rotate Setup Guide" width="600"/>
</div>


**Prerequisites:** n9router must be running (`npm install -g n9router` → `n9router`).

**Step 1 — Add Antigravity accounts to the pool**

Go to **Dashboard → Providers → Antigravity** and connect at least one account via OAuth. Repeat for every additional account you want in the rotation pool.

> **Shortcut:** If you already use Antigravity Management Tools, click **"Import Accounts"** inside the Antigravity provider card to bulk-import all existing accounts in one click — no manual OAuth flow needed.

**Step 2 — Start the MITM Server**

Go to **Dashboard → n9router Tools → MITM Server** and click **Start**.

The MITM proxy intercepts HTTPS traffic between Antigravity IDE and its servers. It needs to be running before rotation can work.

**Step 3 — Enable DNS Redirect**

Go to **Dashboard → n9router Tools → DNS Redirect** and click **Enable for Antigravity**.

This redirects your machine's DNS so that Antigravity IDE's API calls are transparently routed through the local MITM proxy.

**Step 4 — Turn on Token Swap Pool**

Go to **Dashboard → n9router Tools → Token Swap Pool** and toggle it **ON**.

Choose your rotation strategy:

| Strategy | When to use |
|----------|-------------|
| **Round-Robin** | You have 3+ accounts and want even load distribution |
| **Sticky** | You have 2 accounts and want to drain one fully before switching |

**Step 5 — Restart Antigravity IDE**

Fully close Antigravity (quit the app, not just minimize it), then reopen it. This is required because DNS redirect only affects **new** connections — existing sessions still talk to the real Antigravity servers and bypass the proxy.

> On macOS: right-click the Antigravity icon in the Dock → **Quit**, then relaunch.
> On Windows: close from the system tray → relaunch.

**Step 6 — Code as usual in Antigravity IDE**

No settings changes needed inside Antigravity. Just use it normally — n9router silently rotates accounts in the background whenever a quota limit or 429 is hit.

```
Antigravity IDE  →  n9router MITM proxy  →  Antigravity Account A
                                         ↓ (429 / quota hit)
                                         →  Antigravity Account B  ← auto-rotated
                                         ↓ (quota hit)
                                         →  Antigravity Account C
                                         ↓ (all on cooldown)
                                         → waits cooldown timer, then retries
```

**Managing the pool from the dashboard:**

- View each account's remaining quota and reset time
- See which account is "next up" in the rotation queue
- Enable / disable individual accounts without removing them
- Reset the sticky streak for a specific account manually
- Watch live cooldown countdowns after a quota hit

> **Note:** Token Swap Pool (Mode B) and MITM Model Routing (Mode A) are mutually exclusive. When Token Swap Pool is enabled, the MITM alias pass-through is bypassed and shown as **"Bypassed"** in the UI. Disable Token Swap Pool to use Model Routing instead.

<details>
<summary><b>📖 Feature Details</b></summary>

### 🚀 RTK Token Saver

Tool outputs (`git diff`, `grep`, `find`, `ls`, `tree`, log dumps...) often eat 30-50% of your prompt budget. RTK detects them and applies smart, lossless compression **before** the request hits the LLM:

- **Filters:** `git-diff`, `git-status`, `grep`, `find`, `ls`, `tree`, `dedup-log`, `smart-truncate`, `read-numbered`, `search-list`
- **Auto-detect:** No config needed — RTK peeks the first 1KB of each `tool_result` and picks the right filter.
- **Safe by design:** If a filter fails, throws, or makes output bigger, RTK silently keeps the original text. Errors never break your request.
- **Universal:** Works across all formats (OpenAI, Claude, Gemini, Cursor, Kiro, OpenAI Responses) because it runs **before** any format translation.
- **Default ON:** Toggle anytime in Dashboard → Endpoint settings.

```
Without RTK: 47K tokens sent to LLM
With RTK:    28K tokens sent to LLM   (40% saved · same context · same answer)
```

### 🎯 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** ↔ **Cursor** ↔ **Kiro** ↔ **Vertex** ↔ **Antigravity** ↔ **Ollama** ↔ **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!

### 📊 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-4-7        (use subscription fully)
  2. glm/glm-5.1               (cheap backup when quota out)
  3. kr/claude-sonnet-4.5      (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. kr/claude-sonnet-4.5      (Claude 4.5 free unlimited)
  2. kr/glm-5                  (GLM-5 free via Kiro)
  3. oc/<auto>                 (OpenCode Free, no auth)

Monthly cost: $0
Quality: Production-ready models + RTK saves 20-40% tokens
```

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

**Problem:** Deadlines, can't afford downtime

**Solution:**
```
Combo: "always-on"
  1. cc/claude-opus-4-7        (best quality)
  2. cx/gpt-5.5                (second subscription)
  3. glm/glm-5.1               (cheap, resets daily)
  4. minimax/MiniMax-M2.7      (cheapest, 5h reset)
  5. kr/claude-sonnet-4.5      (free unlimited)

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

## ❓ Frequently Asked Questions

<details>
<summary><b>📊 Why does my dashboard show high costs?</b></summary>

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.

</details>

<details>
<summary><b>💳 Will I be charged by 9Router?</b></summary>

**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.

</details>

<details>
<summary><b>🆓 Are FREE providers really unlimited?</b></summary>

**Yes!** The current FREE providers (Kiro, OpenCode Free, Vertex) are genuinely free with **no hidden charges**.

These are free services offered by those respective companies:
- **Kiro AI**: Free unlimited Claude 4.5 + GLM-5 + MiniMax via AWS Builder ID / Google / GitHub OAuth
- **OpenCode Free**: No-auth passthrough proxy, models auto-fetched from `opencode.ai/zen/v1/models`
- **Vertex AI**: $300 free credits for new Google Cloud accounts (90 days)

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.

**Discontinued free tiers (no longer recommended):**
- ❌ **iFlow**: Was free unlimited, now changed to paid (2026)
- ❌ **Qwen Code**: Free OAuth tier discontinued by Alibaba on 2026-04-15
- ❌ **Gemini CLI**: Still works, but using it with non-CLI tools (Claude, Codex, Cursor...) may result in account bans — only use if you stick to Gemini CLI itself

</details>

<details>
<summary><b>💰 How do I minimize my actual AI costs?</b></summary>

**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!

</details>

<details>
<summary><b>📈 What if my usage suddenly spikes?</b></summary>

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.

### Docker

Public Docker Hub image:

- [`nightwalker8x/n9router:latest`](https://hub.docker.com/r/nightwalker8x/n9router)
- [`nightwalker8x/n9router:v0.4.26`](https://hub.docker.com/r/nightwalker8x/n9router/tags)

The public image is published as a multi-arch Linux image:

- `linux/amd64` — typical Ubuntu/Debian VPS, Intel/AMD servers, x86_64 desktops
- `linux/arm64` — Apple Silicon Docker Desktop, ARM Linux servers, Raspberry Pi-class hosts

Windows users should run the normal Linux container through Docker Desktop or WSL2. A native Windows container image is not currently published.

```bash
docker pull nightwalker8x/n9router:latest
```

Run with a Docker volume:

```bash
docker run -d \
  --name n9router \
  -p 20128:20128 \
  -e JWT_SECRET="change-this-secret" \
  -e INITIAL_PASSWORD="change-this-password" \
  -e NEXT_PUBLIC_BASE_URL="http://localhost:20128" \
  -v n9router-data:/app/data \
  nightwalker8x/n9router:latest
```

Run with a local data directory:

```bash
mkdir -p ./data/n9router

docker run -d \
  --name n9router \
  -p 20128:20128 \
  -e JWT_SECRET="change-this-secret" \
  -e INITIAL_PASSWORD="change-this-password" \
  -e NEXT_PUBLIC_BASE_URL="http://localhost:20128" \
  -v "$PWD/data/n9router:/app/data" \
  nightwalker8x/n9router:v0.4.26
```

Run with an env file:

```bash
docker run -d \
  --name n9router \
  -p 20128:20128 \
  --env-file ./.env \
  -v n9router-data:/app/data \
  nightwalker8x/n9router:latest
```

Build locally from source for the current machine:

```bash
docker build -t n9router .
```

Platform-specific local builds:

```bash
# macOS with Apple Silicon Docker Desktop, or ARM Linux hosts
docker buildx build --platform linux/arm64 --load -t n9router:local .

# Linux VPS / Intel or AMD hosts
docker buildx build --platform linux/amd64 --load -t n9router:local .
```

> Docker Desktop on macOS runs Linux containers. There is no separate native `darwin/*` Docker image; use `linux/arm64` on Apple Silicon and `linux/amd64` on Intel Macs or Linux x86_64 hosts.

Build and push the current package version plus `latest`:

```bash
# One-time: create/select a buildx builder if Docker Desktop did not create one.
docker buildx create --name n9router-builder --use || docker buildx use n9router-builder

# Builds linux/amd64 + linux/arm64, checks whether the version tag exists remotely,
# then pushes nightwalker8x/n9router:<package.json version> and :latest.
npm run publish:docker

# Rebuild and overwrite the remote version tag when needed.
npm run publish:docker:force
```

Manual equivalent:

```bash
VERSION=$(node -p "require('./package.json').version")

docker buildx build \
  --platform linux/amd64,linux/arm64 \
  -t "nightwalker8x/n9router:${VERSION}" \
  -t nightwalker8x/n9router:latest \
  --push \
  --provenance=false \
  --sbom=false \
  .

# Verify the pushed manifest
docker buildx imagetools inspect "nightwalker8x/n9router:${VERSION}"
```

Build a local image for the current machine only:

```bash
docker buildx build --load -t n9router:local .
```

Container defaults:
- `PORT=20128`
- `HOSTNAME=0.0.0.0`
- `DATA_DIR=/app/data`

Useful commands:

```bash
docker logs -f n9router
docker restart n9router
docker stop n9router && docker rm n9router
```

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `JWT_SECRET` | `9router-default-secret-change-me` | JWT signing secret for dashboard auth cookie (**change in production**) |
| `INITIAL_PASSWORD` | `123456` | First login password when no saved hash exists |
| `DATA_DIR` | `~/.n9router` | Main app database location (`db.json`) |
| `PORT` | framework default | Service port (`20128` in examples) |
| `HOSTNAME` | framework default | Bind host (Docker defaults to `0.0.0.0`) |
| `NODE_ENV` | runtime default | Set `production` for deploy |
| `BASE_URL` | `http://localhost:20128` | Server-side internal base URL used by cloud sync jobs |
| `CLOUD_URL` | `https://9router.com` | Server-side cloud sync endpoint base URL |
| `NEXT_PUBLIC_BASE_URL` | `http://localhost:3000` | Backward-compatible/public base URL (prefer `BASE_URL` for server runtime) |
| `NEXT_PUBLIC_CLOUD_URL` | `https://9router.com` | Backward-compatible/public cloud URL (prefer `CLOUD_URL` for server runtime) |
| `API_KEY_SECRET` | `endpoint-proxy-api-key-secret` | HMAC secret for generated API keys |
| `MACHINE_ID_SALT` | `endpoint-proxy-salt` | Salt for stable machine ID hashing |
| `ENABLE_REQUEST_LOGS` | `false` | Enables request/response logs under `logs/` |
| `AUTH_COOKIE_SECURE` | `false` | Force `Secure` auth cookie (set `true` behind HTTPS reverse proxy) |

| `HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`, `NO_PROXY` | empty | Optional outbound proxy for upstream provider calls |

Notes:
- Lowercase proxy variables are also supported: `http_proxy`, `https_proxy`, `all_proxy`, `no_proxy`.
- `.env` is not baked into Docker image (`.dockerignore`); inject runtime config with `--env-file` or `-e`.
- On Windows, `APPDATA` can be used for local storage path resolution.
- `INSTANCE_NAME` appears in older docs/env templates, but is currently not used at runtime.

### Runtime Files and Storage

- Main app state: `${DATA_DIR}/db.json` (providers, combos, aliases, keys, settings), managed by `src/lib/localDb.js`.
- Usage history and logs: `${DATA_DIR}/usage.json` and `${DATA_DIR}/log.txt`, managed by `src/lib/usageDb.js`.
- Optional request/translator logs: `<repo>/logs/...` when `ENABLE_REQUEST_LOGS=true`.
- Docker persists runtime data under `/app/data`; mount this path with a named volume or host directory.

## 🐛 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-4-7 → glm/glm-5.1 → kr/claude-sonnet-4.5`

**OAuth token expired**
- Auto-refreshed by 9Router
- If issues persist: Dashboard → Provider → Reconnect

**High costs**
- Enable RTK in Dashboard → Endpoint settings (default ON, saves 20-40% tokens)
- Check usage stats in Dashboard
- Switch primary model to GLM/MiniMax
- Use free tier (Kiro, OpenCode Free, Vertex) 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
