What is 9RouterX?

9RouterX is an open-source, self-hosted AI routing gateway, local LLM proxy, and request/response token optimizer written in Go with an embedded Svelte 5 + Vite + Tailwind 4 web dashboard (listening on default port 20128). It exposes a unified OpenAI-compatible (/v1/chat/completions, /v1/messages, /v1/responses, /v1/embeddings, /v1/models) and Anthropic-compatible local proxy endpoint that connects AI coding assistants (Claude Code, Cursor, OpenAI Codex CLI, Cline, Roo Code, OpenCode, Antigravity, Gemini CLI, OpenClaw) to 155 AI providers—comprising 91 API key services, 28 one-click OAuth integrations, 29 free-tier providers (248 cataloged free models across 36 providers, including 24 keyless models requiring zero external provider setup), and 4 web cookie providers.

Why 9RouterX?

AI-assisted software engineering workflows suffer from fragmented monthly subscriptions, sudden upstream rate limits, runaway token billing, and bloated CLI tool context windows. 9RouterX resolves these operational bottlenecks locally at the gateway layer before your requests leave your machine:

• Unused Monthly Quotas & Rate-Limit Interruptions → Smart 3-Tier Cascade (Subscription → Cheap → Free): Stop losing unused monthly subscription credits or hitting 429 Too Many Requests in the middle of a complex multi-file refactor. 9RouterX prioritizes your active Subscription tier first (via 28 one-click OAuth or 4 web cookie providers), overflows seamlessly to Cheap API providers (such as DeepSeek, Groq, Fireworks, or Nebius), and automatically falls back to Free-Tier / Keyless models (248 free models across 36 providers, including 24 keyless models) when primary limits are exhausted.
• Verbose CLI & Tool-Call Outputs → 20–40% Token Saver Suite: Autonomous coding agents regularly burn tens of thousands of input tokens reading raw terminal logs, directory trees, build outputs, and repetitive JSON responses. Built-in RTK compression (internal/tokensaver, internal/compression), 50+ ready-made per-tool output filters (git diff, git log, grep, ripgrep, docker logs, npm install, pnpm, cargo build, go test, terraform plan, kubectl, pytest, and friends), GCF/tabular headroom compression (internal/compression/gcf, internal/headroom), context squeezing, and output style directives (Caveman, Ponytail, ADHD, and Anti-Slop modes) strip redundant noise before forwarding requests upstream.
• Uncontrolled API Spend → Per-Key Financial Governance & Guardrails: Enforce strict daily USD spending ceilings with instant hard cutoffs (internal/budget), per-key request rate limits, CIDR/IP whitelists, per-key system prompt injection, and scoped endpoint permissions (internal/policy, internal/guardrails, internal/keikey) before distributing local gateway keys (sk-...) to autonomous agents, CI pipelines, or team members.
• Silent Endpoint Failures & Broken Tool Calls → Active Health Probing & Auto-Repair: Upstream LLM providers frequently return malformed JSON tool-call arguments, truncated schemas, or suffer silent latency degradation. 9RouterX repairs broken tool-call structures in transit (tool-call repair fallback), guards against SSRF dispatch and leaks via PII masking, and continuously tracks live endpoint health (internal/modelhealth, internal/resilience) with a 3-tier circuit breaker to bypass degraded nodes automatically.
• Redundant Repeated Prompts → Semantic & Prompt Caching: Reduce round-trip latency and API token billing through local vector-similarity semantic caching (internal/semanticcache) combined with automatic upstream prompt cache header passthrough (internal/promptcache) and zero-allocation FastJSON parsing (internal/fastjson).
• Heavy Runtime Dependencies → Single Self-Contained Go Binary: No Node.js runtime memory bloat, no Python virtual environments, and no external PostgreSQL or Redis containers required. Everything—including the reactive Svelte 5 dashboard, SQLite storage engine, MCP server, and MITM inspector—runs from a single native binary across Linux (x64/arm64), macOS (x64/arm64), and Windows (x64).

Quick Start

Install 9RouterX, create your local gateway API key in the dashboard on port 20128, and execute your first routed completion in 3 steps.

1. Install 9RouterX

Option A — Via npm (Recommended for Linux, macOS, and Windows): requires Node.js >= 18.

npm install -g 9routerx

Option B — Via Official Installer Script (Linux / macOS / Windows):

# Linux & macOS
curl -fsSL https://raw.githubusercontent.com/yanstd888/9routerx/main/install.sh | sh

# Windows (PowerShell)
irm https://raw.githubusercontent.com/yanstd888/9routerx/main/install.ps1 | iex

Option C — Prebuilt Standalone Binaries:

Download the standalone archive for linux-x64, linux-arm64, darwin-x64, darwin-arm64, or win32-x64 directly from GitHub Releases.

2. Start & Create API Key

9routerx
# Dashboard: http://localhost:20128 (Default password: 123456 — change in Settings → Profile)
# Next: Settings → API Keys → Create Key → copy your key (sk-...)

• Default Login: First login uses the default compatibility password 123456. Change it immediately in Settings → Profile.
• Gateway Auth Note: RequireApiKey (internal/middleware/auth.go) validates client keys against your local SQLite database (0 keys configured = 401 Authentication required). Always create at least one gateway API key (sk-...) in Settings → API Keys before sending requests.

3. Send Your First Request (Zero-Config Keyless Model)

Once you have created your local gateway key (sk-YOUR-KEY), test the router immediately using one of the 24 built-in keyless models (such as antigravity/gemini-3.7-flash-medium—no upstream provider API key required):

curl http://localhost:20128/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-YOUR-KEY" \
  -d '{
    "model": "antigravity/gemini-3.7-flash-medium",
    "messages": [
      {"role": "user", "content": "Verify 9RouterX local gateway on port 20128 in one sentence."}
    ]
  }'

Keep the Terminal Free (Background Mode)

Run 9RouterX as a background daemon without tying up an active terminal session:

9routerx start          # launch in background (writes DATA_DIR/run/gateway.pid)
9routerx status         # check running PID and active port
9routerx restart        # restart background instance
9routerx logs -n 100    # tail the last 100 lines of DATA_DIR/run/gateway.log
9routerx stop           # stop the background daemon

• PID & Logs: Background state is stored in DATA_DIR/run/gateway.pid and daemon output is written to DATA_DIR/run/gateway.log.
• Windows Note: On Windows, 9routerx stop uses TerminateProcess (which skips graceful in-flight drain). For a graceful drain on Windows, trigger Shutdown from the web dashboard or use 9routerx restart.

Running with Docker (GHCR)

Run 9RouterX in a container with persistent SQLite storage mounted on port 20128:

docker run -d \
  --name 9routerx \
  --restart unless-stopped \
  -p 20128:20128 \
  -v ~/.9router:/data \
  -e DATA_DIR=/data \
  ghcr.io/yanstd888/9routerx:latest

• Experimental Builds: To test bleeding-edge commits from the experimental branch, pull ghcr.io/yanstd888/9routerx:exp (docker pull ghcr.io/yanstd888/9routerx:exp). Experimental workflow builds only publish to the exp tag and never overwrite latest.

Install Alternatives & Build from Source

Release binary: download from GitHub Releases and verify against SHA256SUMS.txt.

Experimental builds: unpublished work ships as experimental builds — GitHub Releases marks them Pre-release (so 9routerx update keeps pointing at stable), and GHCR tags them exp (ghcr.io/yanstd888/9routerx:exp), never latest. Opt in only to help shake out bugs.

Build from source: prerequisites Go 1.27 and Bun 1.x (dashboard is embedded into the binary, so build web first) — then make build. Full flags and steps: wiki — installation.

Start on boot: autostart/service installation is documented in the wiki — installation.

Sharing a Database with 9Router

9RouterX is engineered as a drop-in compatible upgrade for existing 9Router and 9router-go installations. It listens on the exact same default port (20128) and opens the same DATA_DIR/db/data.sqlite database—meaning your configured providers, OAuth connections, combos, client API keys, and usage history carry over automatically without migration.

Deployment Mode	Default DATA_DIR / SQLite Database Path
Linux / macOS (Native)	~/.9router (opens ~/.9router/db/data.sqlite)
Windows (Native)	%APPDATA%\9router (opens %APPDATA%\9router\db\data.sqlite)
Docker Container	Mount host ~/.9router:/data with -e DATA_DIR=/data

• Caveat: Do not run both 9Router and 9RouterX against the same SQLite file simultaneously. Stop the old process first (or back up data.sqlite before switching) so only one binary holds the SQLite write lock.

Providers — connect AI providers and manage custom OpenAI/Anthropic-compatible endpoints

Supported AI Coding Clients

9RouterX works out of the box with any OpenAI-compatible, Anthropic-compatible, MCP, or A2A client:

• Claude Code (@anthropic-ai/claude-code)
• OpenAI Codex CLI
• Cursor
• Antigravity
• Gemini CLI
• OpenCode
• Cline / Roo Code
• OpenClaw

IPv6 Resolution Note (localhost vs 127.0.0.1): Some CLI tools (upstream documentation specifically notes OpenClaw and certain Node/Go CLIs) may resolve localhost to IPv6 ::1 first and fail to connect. If a client refuses to connect via localhost, use explicit IPv4 http://127.0.0.1:20128 instead.

Example 1: Claude Code Setup

Route Claude Code through http://localhost:20128 to enable 20–40% tool-output token compression, 50+ per-tool filters, and multi-provider failover:

export ANTHROPIC_BASE_URL="http://localhost:20128"
export ANTHROPIC_API_KEY="sk-YOUR-KEY"
claude

Example 2: Codex / OpenCode / OpenClaw (Explicit IPv4 127.0.0.1)

export OPENAI_BASE_URL="http://127.0.0.1:20128/v1"
export OPENAI_API_KEY="sk-YOUR-KEY"

Example 3: Cline / Cursor JSON Configuration

{
  "apiProvider": "openai-compatible",
  "openAiBaseUrl": "http://127.0.0.1:20128/v1",
  "openAiApiKey": "sk-YOUR-KEY",
  "openAiModelId": "antigravity/gemini-3.7-flash-medium"
}

Example 4: Gemini CLI / Custom Anthropic-Compatible Clients

export GEMINI_API_BASE_URL="http://127.0.0.1:20128/v1"
export GEMINI_API_KEY="sk-YOUR-KEY"

Free AI Providers & Keyless Models Catalog

9RouterX includes a built-in catalog of 248 free models across 36 providers (verified in freemodels.go), featuring 24 keyless models (antigravity, opencode, blackbox) that work out of the box without upstream provider registration or external API keys.

Adding a Custom Provider

You can register any custom OpenAI-compatible or Anthropic-compatible upstream server directly in the dashboard (http://localhost:20128 → Providers → Add Custom):

• Set custom base URLs for local or private inference servers (vLLM, Ollama, llama.cpp, LM Studio, LiteLLM, or enterprise gateways).
• Inject custom HTTP authentication or routing headers per provider.
• Attach dedicated per-key outbound HTTP/SOCKS5 proxy pools and configure SSRF dispatch guard rules.

Embedded Dashboard Overview

9RouterX compiles a reactive Svelte 5 + Vite + Tailwind 4 management interface (built with shadcn-svelte, bits-ui, and layerchart) directly into the Go binary at http://localhost:20128 (default password: 123456):

• Token Saver & Compression Analytics: Monitor real-time 20–40% token reduction ratios, RTK compression metrics, 50+ ready-made per-tool output filters, GCF/tabular headroom stats, output style directives (Caveman, Ponytail, ADHD, Anti-Slop), context squeezer activity, and semantic cache hit rates.
• Connections & 1-Click OAuth Manager: Configure all 155 providers, trigger browser OAuth flows for 28 providers, import Kiro external_idp JSON credentials, inspect live model health latency, and assemble multi-tier combo routing presets (fallback, round-robin, sticky, capacity, fusion).
• Per-Key Governance & Custom Usage Ranges: Issue client API keys (sk-...) with daily USD hard cutoffs, request rate limits, IP whitelists, and custom system prompts; inspect Tremor-style usage charts across 12h, 14d, or custom date ranges; and inspect full request/response JSON payloads in the Extended Logging & Payload Inspector.

Frequently Asked Questions (FAQ)

1. Does 9RouterX support Claude Code, Cursor, Codex, and Cline?

Yes. 9RouterX exposes both Anthropic-compatible (http://localhost:20128) and OpenAI-compatible (http://localhost:20128/v1) endpoints, alongside built-in MCP Server and A2A protocol support. You can connect Claude Code, Cursor, OpenAI Codex CLI, Cline, Roo Code, OpenCode, OpenClaw (use explicit IPv4 http://127.0.0.1:20128), Antigravity, and Gemini CLI directly to port 20128.

2. Is 9RouterX free, and how do the 24 keyless models work?

Yes. 9RouterX is 100% free and open-source software (MIT License) that runs locally as a single binary with zero proxy markup fees. It ships with 29 free-tier providers and 248 cataloged free models across 36 providers—including 24 keyless models (antigravity, opencode, blackbox, such as antigravity/gemini-3.7-flash-medium) that require no external provider API key. You only need to generate a local 9RouterX gateway key (sk-...) in the dashboard (http://localhost:20128, default password 123456) to authenticate your local client against RequireApiKey.

3. How is 9RouterX different from LiteLLM or OpenRouter?

• Versus OpenRouter: OpenRouter is a cloud intermediary that adds per-token markup fees and routes prompts through external third-party servers. 9RouterX runs 100% locally on your machine as a single binary with zero markup.
• Versus LiteLLM: LiteLLM requires a Python environment; advanced budget/usage tracking needs external databases (PostgreSQL/Redis). 9RouterX compiles a full AI gateway, Svelte 5 dashboard, 20–40% Token Saver suite (with 50+ per-tool filters), semantic cache, per-key USD budget cutoffs, and 28 one-click OAuth flows into a single zero-dependency Go binary backed by an embedded SQLite file.

4. How does the 20–40% Token Saver work without breaking code generation?

AI coding agents consume massive context windows when reading CLI outputs, directory listings, and tool responses. 9RouterX's tokensaver and compression modules apply RTK compression, 50+ ready-made per-tool output filters (git diff, grep, docker logs, npm install, terraform plan), GCF tabular headroom compression, context squeezing, output style directives (Caveman, Ponytail, ADHD), and anti-slop rules to tool outputs in transit—cutting 20–40% of token volume while repairing malformed JSON tool calls automatically.

5. Can I migrate from 9Router or 9router-go without losing my keys and combos?

Yes. 9RouterX shares the exact same default port (20128) and SQLite database schema (DATA_DIR/db/data.sqlite). Stop your existing 9Router instance and start 9RouterX—all providers, OAuth connections, combos, client API keys, and usage statistics carry over immediately without migration scripts.

6. What happens when my primary AI subscription hits a rate limit?

When a request hits a 429 rate limit, quota exhaustion, or upstream 5xx error, 9RouterX's resilience circuit breaker and modelhealth probes automatically cascade the request through your configured combo tier (Subscription OAuth → Cheap API Key → Free-Tier / Keyless) without dropping your active coding session.

7. How do I run 9RouterX in the background or update to the latest release?

Use the built-in daemon commands: 9routerx start, 9routerx status, 9routerx restart, 9routerx logs -n 100, and 9routerx stop. To update, run npm install -g 9routerx@latest, 9routerx update, or pull the latest GHCR container (ghcr.io/yanstd888/9routerx:latest).

Contributing

Issues and pull requests use templates, so pick the right one rather than opening a blank report:

• Bug report — something behaves incorrectly. Include a reproduction, 9routerx version, OS, and the log excerpt around the failure.
• Feature request — the problem you cannot solve today, the surface it touches, and whether upstream already has it.
• Question — configuration and usage help.

PRs follow the checks CI runs: go vet ./..., go test -count=1 ./..., make test-integration, plus cd web && bun test and make vet-svelte for anything touching the dashboard. Before writing code, skim AGENTS.md — provider isolation and the Go/Svelte conventions keep reviews fast.

Docs

Full documentation, searchable: 9routerx Wiki — installation, usage, API reference, dashboard, providers, governance, architecture, database, CLI, and a screenshot gallery. Every page supports ?q= search and #section deep links.

Repository references:

• ARCHITECTURE.md — routing, providers, runtime layout
• DATABASE.md — SQLite schema & operator contract
• CHANGELOG.md — release history. Work merged since the last tag lives in .changes/ fragments and is folded in at the next release; the dashboard's changelog modal shows both. Check what you are running with 9routerx version.
