9Router - FREE AI Router & Token Saver
Never stop coding. Save 20-40% tokens with RTK + auto-fallback to FREE & cheap AI models.
Connect All AI Code Tools (Claude Code, Cursor, Antigravity, Copilot, Codex, Gemini, OpenCode, Cline, OpenClaw...) to 40+ AI Providers & 100+ Models.
🤔 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 ($20-50/month per provider)
9Router solves this:
- ✅ RTK Token Saver - Auto-compress tool_result, save 20-40% tokens
- ✅ Maximize subscriptions - Track quota, use every bit before reset
- ✅ Auto fallback - Subscription → Cheap → Free, zero downtime
- ✅ Multi-account - Round-robin between accounts per provider
- ✅ Universal - Works with any OpenAI/Claude-compatible CLI
⚡ Quick Start
Option 1 — npm (recommended for desktop):
npm install -g 9router
9router
# Or run directly with npx
npx 9router
Option 2 — Docker (server/VPS):
docker run -d --name 9router -p 20128:20128 \
-v "$HOME/.9router:/app/data" -e DATA_DIR=/app/data \
decolua/9router:latest
Published images: 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.
