The data plane for agents. Arch is a models-native proxy server that handles the plumbing work in AI: agent routing & hand off, guardrails, zero-code logs and traces, unified access to LLMs from OpenAI, Anthropic, Ollama, etc. Build agents faster, and scale them reliably.

High-performance lightweight proxy and load balancer for LLM infrastructure. Intelligent routing, automatic failover and unified model discovery across local and remote inference backends.

Customize and Extend Claude Code with ccproxy: Route to OpenAI, Gemini, Qwen, OpenRouter, and Ollama. Gain full control of your Claude Max/Pro Subscription with your own router.

Open Source LLM proxy that transparently captures and logs all interactions with LLM API

This is a robust and configurable LLM proxy server built with Node.js, Express, and PostgreSQL. It acts as an intermediary between your applications and various Large Language Model (LLM) providers

A personal LLM gateway with fault-tolerant capabilities for calls to LLM models from any provider with OpenAI-compatible APIs. Advanced features like retry, model sequencing, and body parameter injection are also available. Especially useful to work with AI coders like Cline and RooCode and providers like OpenRouter.

OpenAI-compatible HTTP LLM proxy / gateway for multi-provider inference (Google, Anthropic, OpenAI, PyTorch). Lightweight, extensible Python/FastAPI—use as library or standalone service.

Local LLM proxy, DevOps friendly

Allows any BYOK AI editor or extension, such as Cursor or Continue, to connect to any openai-compatible LLM by aliasing it as a different model

Proxy for many LLM-provider with OpenAI like request

A self-hosted, open-source (Apache 2.0) proxy for LLM's with prometheus metrics

Connect any LLM-powered client app, such as a coding agent, to any supported inference backend/model.

Store your knowledge (privately), lead LLMs with it and cure hallucinations.

A proxy for claude code to use liteLLM

Nodejs OpenRouter proxy inference that provides all nessary endpoints for your LLM application.

AI Proxy Server - A high-performance, secure unified API gateway for multiple LLM providers (OpenAI, Gemini, Groq, OpenRouter, Cloudflare) with intelligent routing, rate limiting, and streaming support. Features modular architecture, enhanced security, and optimized performance.

[WIP] Sorai is a lightweight, high-performance, and open-source LLM proxy gateway.

A TypeScript wrapper to seamlessly route multiple Vercel AI providers by model name, offering unparalleled flexibility and extensibility for managing diverse AI services—inspired by the provider-routing architecture of litellm but optimized for TypeScript/Vercel workflows
