Open source LLM gateway: one OpenAI compatible key for every major AI provider

UnoRouter is an open source LLM gateway built for small teams that want to ship AI features without signing up with every model lab. One OpenAI compatible endpoint and one key give you GPT, Claude, Gemini, DeepSeek, Qwen, Mistral and more, so trying a different model is a one word change in your config.
When an upstream provider is slow or down, requests move to a healthy one automatically. It works with the official OpenAI SDKs, Claude Code, Cline and SillyTavern, the built in chat keeps conversations in your browser, and billing starts with a free tier and continues pay as you go with no subscription.
Startups rarely know which model will fit a feature best, and committing to one vendor early means rewriting integrations later. UnoRouter keeps that choice open: one integration, one bill, every major provider, plus failover so a vendor outage does not become your outage.
