LLM gateways
Reviewed resources in LLM gateways. 106 resources listed.
CNLLM - Chinese LLM Adapter
github.comA Python toolkit giving a single OpenAI-compatible interface across Chinese large language models, so frameworks such as LangChain and LlamaIndex can call them without model-specific adapter code.
OpenCode for GitHub Copilot Chat
github.comA VS Code extension that plugs a third-party model gateway into GitHub Copilot Chat's model picker, adding dozens of additional language models through a user-supplied key instead of a separate chat interface.
Corpus OS
corpusos.comAn open-source, wire-first SDK that standardizes LLM, embedding, vector and graph infrastructure behind one protocol, so an application can swap providers without rewriting integration code across LangChain, LlamaIndex, AutoGen, CrewAI or MCP.
Langcli
langcli.comA terminal AI coding assistant compatible with Claude Code's configuration and skills, built to switch between multiple LLM providers within one session through its own router integration.
AI Grid
autonomous.aiA tool that networks computers a user already owns into a single OpenAI-compatible endpoint, routing each inference or training request to whichever machine runs the right model, with no account or relay required.
1flowbase
1flowbase.taichuy.comA self-hosted AI gateway and application backend that an AI agent can operate end to end through MCP: routing model traffic, defining data models that become database tables and CRUD APIs, and assembling React frontend blocks.
Agentic API
vllm-project.github.ioA Rust-native, stateful API gateway that sits in front of vLLM and implements an OpenAI-compatible Responses API server-side, so a client makes one call and the server manages conversation state, tool execution and streaming.
Olla
tensorfoundry.ioA lightweight proxy and load balancer for self-hosted LLM infrastructure, routing requests across local and remote inference backends with automatic failover and a unified model catalogue.
ORBIT
github.comA self-hosted AI gateway that connects files, databases, APIs and MCP tools to local or hosted models behind one OpenAI-compatible API, with authentication, observability and an admin UI.
LLM
github.comA Rust library and command-line tool that lets an application call OpenAI, Anthropic, Ollama, DeepSeek, Google, Cohere, Mistral, Hugging Face, ElevenLabs and other LLM backends through one unified, builder-style API.
CSSwitch
github.comA macOS menu-bar app that routes the Claude Science desktop client to a third-party model API, such as DeepSeek, Qwen, GLM, Kimi, MiniMax or any OpenAI- or Anthropic-compatible endpoint, and can switch back to the official Claude account at any time.
A self-hosted proxy that exposes OpenAI- and Anthropic-compatible endpoints backed by multiple LLM providers, with automatic API key rotation, failover and rate-limit handling.
Lynkr
lynkrhq.comAn LLM gateway and CLI proxy that compresses tool outputs, caches semantically similar requests, and routes each request across more than a dozen providers by complexity, including wrapping an existing Claude Code or Codex subscription.
mimo2codex
mimodoc.chengj.onlinemimo2codex is a local proxy that lets the latest OpenAI Codex CLI or desktop app talk to other large language models, with built-in support for Xiaomi MiMo and DeepSeek and a generic mechanism for any OpenAI-compatible or native Responses API provider.
Casbin Gateway
gateway.casbin.orgCasbin Gateway is a local dashboard and proxy that shows what every AI coding agent on a machine is doing, grades whether an API key's provider matches what was paid for, and centralizes model access, permissions and spend tracking across 44 vendors.
CodexSaver
github.comCodexSaver is an MCP tool that turns Codex into a cost-aware router, delegating low-risk, easily verified work such as explanations, searches, reviews and bounded patches to a cheaper worker while keeping architecture, security and final review decisions in Codex itself.
UncommonRoute
github.comUncommonRoute is an automatic LLM router that plugs into Claude Code, Cursor, Codex or the OpenAI SDK, running locally to send each request to a cheaper or stronger model depending on how complex the request is.
Duel Agents
github.comA routing service and set of IDE plugins that sends a coding assistant's prompts to several language models at once and returns whichever answer wins on cost and quality, reached through a paid gateway API key.
ThinkWatch
thinkwat.chAn enterprise AI gateway that proxies OpenAI, Anthropic, Gemini and self-hosted LLM APIs plus MCP tool calls behind one control plane, with RBAC, audit logs, rate limiting and cost tracking.
AI Gateway Labs
aka.msA set of over 30 hands-on Jupyter notebook labs that show how to secure, meter and observe large language models, MCP servers and AI agents behind Azure API Management's AI Gateway.
OneAPI Pro
one-api.proAn enterprise-grade AI API gateway, built as an extended fork of one-api, that adds subscription plans, active-active clustering, and precise billing for reselling or managing access to multiple model providers.
AIHelms
aihelms.cnAIHelms is an enterprise platform for managing an organization's AI resources: a unified gateway across providers such as OpenAI, Azure, Claude and DeepSeek, per-department budgets and token-level cost attribution, and registration of internal MCP tools and Skills.
Copilot API
caozhiyuan.github.ioCopilot API is a local AI gateway that exposes GitHub Copilot, a built-in Codex provider and configurable third-party model providers through one OpenAI- and Anthropic-compatible endpoint, so tools such as Claude Code, OpenCode and Codex can all talk to the same local server.
search2ai
sum4all.siteA self-hosted search gateway for AI agents that exposes a single Perplexity-compatible search API backed by several providers, falling back to the next one automatically if one is rate-limited or down.
