self-hosted free LLM API gateway
Self-hosted HTTP API that gives free, keyless access to many LLM providers (Gemini, DeepSeek, Claude, GPT) with optional GUI and Docker.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
Choose if you want a TypeScript OpenAI-compatible server focused on official web-UI providers like DeepSeek, GLM, and Kimi.
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.
Choose if you prefer a Go binary and need reverse-engineered OpenAI endpoints for Cursor, Windsurf, Bing, and similar services.
集成了openai-api、coze、deepseek、cursor、windsurf、qodo、blackbox、you、grok、bing 绘画 多款AI的聊天逆向接口适配到 OpenAI API 标准接口服务端。
Choose for a larger, actively maintained Python provider collection with its own web UI when you don't need this seed's single-endpoint wrapper.

Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
Choose when you already have paid provider keys and need cost tracking, guardrails, and load balancing instead of keyless free access.
The fastest, litest AI Gateway. Rust core with Python SDK. Call 100+ LLM APIs in OpenAI (or native) format with cost tracking, guardrails, load balancing, and logging [Bedrock, Azure, OpenAI, Anthropic, OpenAI, VertexAI, vLLM, Nvidia NIM]
Choose for multi-tenant key management and resale with a web admin UI, but it expects provider API keys.
LLM API 管理 & 分发系统，支持 OpenAI、Azure、Anthropic Claude、Google Gemini、DeepSeek、字节豆包、ChatGLM、文心一言、讯飞星火、通义千问、360 智脑、腾讯混元等主流模型，统一 API 适配，可用于 key 管理与二次分发。单可执行文件，提供 Docker 镜像，一键部署，开箱即用。LLM API management & key redistribution system, unifying multiple providers under a single API.

Choose as a Python library/CLI for embedding free provider access into scripts rather than running an HTTP server.
LLM4Free — All-in-one Python toolkit for web search, AI interaction (40+ free providers), digital utilities, and more. Formerly WebScout.
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
Choose only for legacy ChatGPT reverse-engineering support; last push 3.1 years ago and limited to ChatGPT.
Reverse engineered ChatGPT API
These projects were analysed and named Free-GPT4-WEB-API among their alternatives. The relationship is not symmetric — how Free-GPT4-WEB-API rates them is a separate judgement, made when Free-GPT4-WEB-API is analysed in its own right.
calls Free-GPT4-WEB-API “Pick when you need a smaller self-hosted Python API for free access to latest models without the full g4f client suite.”
