when you only need local routing and model config for Claude Code agents, not a multi-tenant production gateway.

One local control plane for every AI agent: route across models, fuse new capabilities, orchestrate tools, and stay fully in control.

when you need to point Codex/Claude Code CLIs at arbitrary models, not to serve production traffic.

Universal provider proxy for OpenAI Codex & Claude Code — use any LLM (Claude, Gemini, Grok, DeepSeek, Ollama…) with Codex CLI, App, SDK, and Claude Code

when your upstreams are consumer AI clients and you want multi-protocol translation instead of enterprise gateway features.

Self-hosted multi-protocol AI API proxy for Antigravity, Codex, Grok, Kiro, OpenAI, Claude, and custom providers. Supports OpenAI-compatible API, Claude API, Gemini protocol conversion, GPT, Grok Build, Claude Opus, Gemini Pro, Kimi, MiniMax, provider pools, smart routing, and automatic failover.

when your upstreams are coding CLIs and you need multi-tenant quotas and logs rather than provider-API routing.

Self-hosted AI gateway for coding CLIs — one OpenAI/Claude/Gemini/Codex-compatible endpoint, with a multi-tenant web console, request logs, and spend quotas.

when the goal is free or cheap coding-agent traffic in JavaScript rather than a hardened gateway.

Unlimited FREE AI coding. Connect Claude Code, Codex, Cursor, Cline, Copilot, Antigravity to FREE Claude/GPT/Gemini via 40+ providers. Auto-fallback, RTK -40% tokens, never hit limits.

when your agents pay per call in crypto and need sub-millisecond local routing, not an enterprise gateway.

The agent-native LLM router for autonomous agents. Every frontier model behind one wallet, <1ms local routing, USDC payments on Base & Solana via x402.

when you want to expose Windsurf/Devin desktop model access as an API instead of routing provider keys.

Turn Windsurf / Devin Desktop's 100+ AI models (Claude, GPT, Gemini, DeepSeek, Kimi, GLM, SWE) into OpenAI-, Anthropic- & Gemini-compatible APIs. Zero-dependency self-hosted reverse proxy for Claude Code, Cline & Cursor. 把 Windsurf/Devin 云端 100+ 模型变成三套兼容 API。

when you want free access by scraping official web UIs, accepting breakage and no production guarantees.

Chat2API enables zero-cost access to leading AI models by leveraging official web UIs. It supports providers such as DeepSeek, GLM, Kimi, MiniMax, Qwen, and Z.ai, and seamlessly integrates with tools like openlcaw, Cline, and Roo-Code.
