Clash for AI：统一管理多平台AI服务的本地网关解决方案

Clash for AI is an open-source AI service management tool that acts as a local gateway to unify multiple中转 API service providers and native large models. It provides a single access endpoint for tools like Cursor, Claude Code, etc., solving the pain point of managing configurations across multiple tools. This post will break down its background, design, usage, and value.

With the rapid development of LLMs, AI developers and users face a growing problem: efficiently switching and managing configurations between numerous model providers and development tools. For example, a developer using Cursor, Claude Code, Cherry Studio, and scripts has to configure API keys, base URLs, and model names separately for each tool. Changing providers or models requires modifying each tool's config one by one—tedious and error-prone. This is the core issue Clash for AI aims to solve.

Clash for AI integrates multiple AI中转 APIs, native model sources, and local AI tools behind a unified local endpoint. Inspired by the proxy tool Clash, it uses http://127.0.0.1:3456/v1 as the single endpoint. Key advantages:

1. One-time config: All OpenAI-compatible tools only need to set the local endpoint once (Base URL: http://127.0.0.1:3456/v1, API Key: dummy or any value).
2. Centralized management: Visual web interface for adding/managing providers, checking health status, viewing logs, etc.
3. Seamless switching: Change active providers in the interface—all tools switch automatically without extra config.

Clash for AI uses a modular two-layer architecture:

• Providers Module: Manages upstream remote services (e.g., new-api, one-api). Functions: add/edit provider info, switch active providers, health checks, view available models, map Claude Code model slots.
• Models Module: Manages local model gateways for direct connection to official APIs (OpenAI, Anthropic). Functions: add model sources, detect/define model IDs, enable/disable sources. Hierarchy: Models config local gateways → local gateway appears in Providers list → Providers is the main interface for selecting active upstream. This design combines中转 service convenience and official API flexibility.

Clash for AI supports multiple deployment methods: Desktop: Download from Release page for macOS/Windows/Ubuntu Desktop. macOS users may need to handle security warnings (move to /Applications, right-click open, or use sudo xattr -rd com.apple.quarantine "/Applications/Clash for AI.app"). Server: Use command line installer (curl -fsSL https://raw.githubusercontent.com/xiaoyuandev/clash-for-ai/main/scripts/install.sh | bash). Default endpoints: Web UI (http://127.0.0.1:3456), API (http://127.0.0.1:3456/v1). Service management via systemd or CLI commands (start/stop/restart/status/logs). Remote access via SSH tunnel or reverse proxy (Nginx/Caddy).

Usage Steps:

1. Configure providers in the Providers page (name, Base URL, API Key).
2. (Optional) Configure local models in the Models page for direct official API access.
3. Set all AI tools to use the unified config (Base URL: http://127.0.0.1:3456/v1, API Key: dummy).
4. Switch active providers in the interface as needed. Deep Link Import: Supports one-click config import from web pages (e.g., https://www.clashforai.com/deeplink.html), simplifying service access. Application Scenarios: Multi-provider redundancy, team collaboration standardization, cost optimization, privacy-sensitive scenarios, model evaluation comparison.

Technical Highlights:

• Pure local gateway: Runs locally, no user data passes through third-party servers (privacy control).
• OpenAI-compatible API: Follows OpenAI specs for seamless integration with most AI tools.
• Modular design: Separates Providers and Models for flexibility.
• Cross-platform: Supports macOS, Windows, Linux (desktop and server). Project Status: Open-source on GitHub,登上 GitHub Trending, recommended on Product Hunt. Documentation site (https://www.clashforai.com/) provides detailed guides. Community supports English and Chinese docs, welcomes service providers to join Deep Link ecosystem.

Clash for AI precisely solves the config management pain points for AI developers using multiple tools/services. By abstracting a unified local gateway, it simplifies config switching to a single click, greatly improving development efficiency. It's ideal for developers using multiple AI tools, offering benefits like simplified operations, team collaboration support, and cost control. As the AI ecosystem grows, such infrastructure tools will become increasingly important—letting developers focus on value creation instead of config management.
