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

🚀 Step-by-Step Setup

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.

💡 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 | | 🚀 RTK Token Saver | Auto-compress tool_result content (git-diff, grep, find, ls, tree...) before sending to LLM | Save 20-40% tokens per request, keep more context window | | 🎯 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 ↔ Cursor ↔ Kiro ↔ Vertex | 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 |

🚀 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!

🌐 Deploy Anywhere

📊 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! 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

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.

OpenClaw

Option 1 — Dashboard (recommended):

Dashboard → CLI Tools → OpenClaw → Select Model → Apply

Option 2 — Manual: Edit ~/.openclaw/openclaw.json:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "9router/kr/claude-sonnet-4.5"
      }
    }
  },
  "models": {
    "providers": {
      "9router": {
        "baseUrl": "http://127.0.0.1:20128/v1",
        "apiKey": "sk_9router",
        "api": "openai-completions",
        "models": [
          {
            "id": "kr/claude-sonnet-4.5",
            "name": "Claude Sonnet 4.5 (Kiro Free)"
          }
        ]
      }
    }
  }
}

Note: OpenClaw only works with local 9Router. Use 127.0.0.1 instead of localhost to avoid IPv6 resolution issues.

Docker

Public Docker Hub image:

• nightwalker8x/n9router:latest
• nightwalker8x/n9router:v0.4.26

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.

docker pull nightwalker8x/n9router:latest

Run with a Docker volume:

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:

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:

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:

docker build -t n9router .

Platform-specific local builds:

# 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:

# 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:

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:

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

Container defaults:

• PORT=20128
• HOSTNAME=0.0.0.0
• DATA_DIR=/app/data

Useful commands:

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) | | REQUIRE_API_KEY | false | Enforce Bearer API key on /v1/* routes (recommended for internet-exposed deploys) | | 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

🛠️ Tech Stack
