🤔 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)

9Router solves this:

• ✅ RTK Token Saver - Auto-compress tool_result, save 20-40% tokens
• ✅ 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 any OpenAI/Claude-compatible CLI

⚡ Quick Start

Option 1 — npm (recommended for desktop):

npm install -g @raruu/9router
9router

# Or run directly with npx
npx @raruu/9router

Option 2 — Docker (server/VPS), upstream images:

docker run -d --name 9router -p 20128:20128 \
  -v "$HOME/.9router:/app/data" -e DATA_DIR=/app/data \
  decolua/9router:latest

Published images (upstream, not this fork): Docker Hub • GHCR (multi-platform amd64/arm64).

🎉 Dashboard opens at http://localhost:20128

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

Dashboard → Providers → Connect Kiro AI (free Claude unlimited) or OpenCode Free (no auth) → Done!

3. Use in your CLI tool:

Claude Code/Codex/OpenClaw/Cursor/Cline Settings:
  Endpoint: http://localhost:20128/v1
  API Key:  [copy from dashboard]
  Model:    kr/claude-sonnet-4.5

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

🚀 CLI Options

9router                    # Start with default settings
9router --port 8080        # Custom port
9router --no-browser       # Don't open browser
9router --skip-update      # Skip auto-update check
9router --help             # Show all options

Dashboard: http://localhost:20128/dashboard

🔌 Connect to a Remote 9Router

Already running 9Router on another machine (e.g. a team server on your LAN)? Point this machine's CLI tools at it — no local server is started:

npx 9router connect http://<server-host>:20128                       # pick tools interactively
npx 9router connect http://<server-host>:20128 --tools claude,codex  # or choose up front
npx 9router connect --reset --tools claude,codex                     # undo

It logs in with the dashboard password (hidden prompt), reuses or creates an API key named cli-<hostname>, and writes each tool's config (backing up the original once as *.bak-9router).

Supported: claude, codex, opencode, droid, crush, kilo, cline, or all. Other options: --model, --opus/--sonnet/--haiku/--fable, --api-key, --key-name, --print-env. See 9router connect --help.

⚠️ Over plain http:// the password and API key are sent unencrypted — use a trusted LAN/VPN or put HTTPS in front. The API key is stored in each tool's config file.
