🤔 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-proxy
9router-proxy

# Or run directly with npx
npx 9router-proxy

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-proxy              # Start with default settings (interactive)
9router-proxy start        # Start headless background server (log: ~/.9router/server.log)
9router-proxy status       # Show background server status
9router-proxy stop         # Stop background server
9router-proxy --port 8080        # Custom port
9router-proxy --no-browser       # Don't open browser
9router-proxy --skip-update      # Skip auto-update check
9router-proxy --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-proxy connect http://<server-host>:20128                       # pick tools interactively
npx 9router-proxy connect http://<server-host>:20128 --tools claude,codex  # or choose up front
npx 9router-proxy 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 tools: claude, codex, opencode, droid, crush, kilo, cline, pi, omp, or all.

Models

Models come from the server's own CLI-tools configuration, so a client gets whatever the operator already picked on the dashboard. Nothing is hardcoded.

| Tool | Model taken from (first match wins) | |---|---| | claude | tier flag (--opus …) → server's Claude tier → left unset (Claude Code's own default) | | others | --model → that tool's own model on the server → server's OpenCode model → tool skipped |

kilo has no readable model on the server, so it always uses --model or the OpenCode model. omp (Oh My Pi) needs no model: it uses proxy discovery, so every server model appears under 9router in /model. A Claude tier the server doesn't set is removed from your config rather than kept from an earlier run. A skipped tool makes the command exit 1.

Overriding the server's models

# One Claude tier; the other tiers still come from the server
npx 9router-proxy connect http://<server-host>:20128 --tools claude --sonnet cc/claude-sonnet-5-5

# Every Claude tier
npx 9router-proxy connect http://<server-host>:20128 --tools claude \
  --fable cc/claude-fable-5-1 --opus cc/claude-opus-5-5 \
  --sonnet cc/claude-sonnet-5-5 --haiku cc/claude-haiku-4-5-20251001

# All non-Claude tools at once
npx 9router-proxy connect http://<server-host>:20128 --tools codex,opencode,kilo --model ocg/deepseek-flash

# Claude and other tools in one run
npx 9router-proxy connect http://<server-host>:20128 --tools claude,codex --opus cc/claude-opus-5-5 --model gpt-6

# A different model per tool: --model covers every non-Claude tool in a run, so run once per tool
npx 9router-proxy connect http://<server-host>:20128 --tools codex --model gpt-6
npx 9router-proxy connect http://<server-host>:20128 --tools opencode --model ocg/glm-5.3

A model the server doesn't list is still written, with a not listed by server warning. To see the ids it serves: curl http://<server-host>:20128/v1/models -H "Authorization: Bearer <your key>".

Checking the current config

9router-proxy show prints what each CLI tool on this machine is currently set to — base URL, masked API key and models. It only reads local files and never contacts a server.

npx 9router-proxy show                 # every supported tool
npx 9router-proxy show claude          # one tool
npx 9router-proxy show claude codex    # several
npx 9router-proxy show claude --json   # machine-readable (key still masked)

✅ Claude Code
   File:     ~/.claude/settings.json
   Base URL: http://<server-host>:20128/v1
   API key:  sk-a1b…9f3c
   Models:
     fable   cc/claude-fable-5-1
     opus    cc/claude-opus-5-5
     sonnet  cc/claude-sonnet-5-5

Tools not pointed at 9router are listed as not configured. For Codex, OpenCode and Cline it also warns when a 9router entry exists but another provider is the active one.

Other options

| Option | Purpose | |---|---| | --password <pw> | Dashboard password (or NINE_ROUTER_PASSWORD); prompted if omitted — preferred, keeps it out of shell history | | --save | After a successful login, save the password for this server to ~/.9router/connect.env (plain text, mode 600) so later runs skip the prompt. Delete the file to forget it | | --api-key <key> | Use this key and skip login. The server's models can't be read without a login, so pass model flags | | --key-name <name> | API key name to reuse/create (default cli-<hostname>) | | --print-env | Also print OPENAI_BASE_URL / OPENAI_API_KEY for other CLIs | | --reset | Remove the 9router settings from the selected tools |

See 9router-proxy connect --help for the full list.

⚠️ 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.
