Overview
CoAI pairs a multi-user chat frontend with an OpenAI-compatible API proxy and billing for operators of commercial AI sites. A Go backend on MySQL and Redis routes across channels with priority, weight, retries and model redirection for OpenAI, Anthropic, Gemini, Midjourney, Ollama and more; the React UI adds file parsing, SearXNG search and image generation. Docker Compose serves it on port 8000.
Who it is for: operators running a paid multi-user ChatGPT-style site
