A High-Availability, Transparent, and Smart Multi-Vendor Proxy for Claude Code

---

💡 Why Do We Even Need coding-proxy?

When you're deeply immersed in your coding "zone" with Claude Code (or any AI assistant relying on Anthropic's Messages API), there's nothing quite as soul-crushing as having your flow violently interrupted by:

• 🛑 Rate Limiting: High-frequency pings trigger the dreaded 429 rate_limit_error. Forced to stare at the screen and rethink your life choices.
• 💸 Usage Cap: Aggressive code generation drains your daily/monthly quota, slamming you with a cold, heartless 403 error.
• 🌋 Overloaded Servers: Anthropic's official servers melt down during peak hours, tossing back a merciless 503 overloaded_error.

coding-proxy was forged in the developer fires to terminate these exact pain points. Serving as a purely transparent intermediate layer, it blesses your Claude Code with millisecond-level "N-tier chained fallback disaster recovery." When your primary vendor goes belly up, it seamlessly and instantly switches your requests to the next smartest available fallback (like GitHub Copilot, Google Antigravity, or even Zhipu GLM)—with zero manual intervention, and zero perceived interruption.

🌟 Core Features

• ⛓️ N-tier Chained Failover: Autonomous descending sequence, supporting Claude's official plans, as well as Coding Plans from GitHub Copilot, Z AI, MiniMax, Alibaba Qwen, Xiaomi, Kimi, Doubao, etc.
• 🛡️ Smart Resilience & Quota Guardians: Every single vendor node comes fully armed with an independent Circuit Breaker and Quota Guard to proactively dodge avalanches without breaking a sweat.
• 👻 Phantom-like Transparency: 100% transparent to the client! No code tweaks required. Overwrite ANTHROPIC_BASE_URL with a single line, and you're good to go.
• 🔄 Universal Alchemy (Formats & Models): Native support for two-way request/streaming (SSE) translations between Anthropic ←→ Gemini. Plus, auto/DIY model name mapping (e.g., effortlessly morphing claude-* into glm-*).
• 📊 Extreme Observability: Built-in, zero-BS local monitoring powered by a SQLite WAL. The CLI provides a one-click detailed Token usage dashboard (coding-proxy usage).
• ⚡ Featherweight Standalone Deployment: A fully asynchronous architecture (FastAPI + httpx). Zero dependency on Redis, message queues, or other heavy machinery—absolutely no extra baggage for your dev rig.

🚀 Quick Start

1. Prerequisite Checks

Make sure your rig has Python 3.12+ and the uv package manager installed (highly recommended, because life is too short for slow package managers).

2. Lightning Install

uv add coding-proxy

3. Ignite the Proxy Server

## (Optional) Highly recommended to enable Zhipu GLM. Use env vars to defensively inject your keys
# export ZHIPU_API_KEY="your-api-key-here"

# Start coding-proxy with the default configuration
# The default config lives at: ~/.coding-proxy/config.yaml.
uv run coding-proxy start

## Use the `-c` flag to gracefully point to a custom config path
# uv run coding-proxy start -c ./coding-proxy.yaml

# INFO:     Started server process [1403]
# INFO:     Waiting for application startup.
# ...
# INFO:     coding-proxy started: host=127.0.0.1 port=8046
# INFO:     Application startup complete.
# INFO:     Uvicorn running on http://127.0.0.1:8046 (Press CTRL+C to quit)

4. Seamless Claude Code Integration

Open a fresh terminal tab and route your traffic through coding-proxy before firing up Claude Code:

export ANTHROPIC_BASE_URL=http://127.0.0.1:8046

# Enjoy blissful, silky-smooth, and uninterrupted coding nirvana:
claude

🛠️ The CLI Console Guide

coding-proxy comes equipped with a badass suite of CLI tools to help you boss around your proxy state.

Command	Description	Example Usage
start	Fire up the proxy server. Supports custom ports and configuration paths.	coding-proxy start -p 8080 -c ~/config.yaml
status	Check proxy health. Shows circuit breaker states (OPEN/CLOSED) and quota status across all tiers.	coding-proxy status
usage	Token Stats Dashboard. Stalks every single token consumed, failovers triggered, and latency across day/vendor/model dimensions.	coding-proxy usage -d 7 -v anthropic
reset	The emergency flush button. Force-reset all circuit breakers and quotas instantly when you've confirmed the main vendor is back from the dead.	coding-proxy reset

📐 Architectural Panorama

When a request inevitably hits the fan, the RequestRouter slides gracefully down the N-tier tree, juggling circuit breakers and token quotas to decide the ultimate destination:
