UnoRouter

UnoRouter is a lean API gateway for builders of micro SaaS products who want AI features without a pile of vendor accounts. One OpenAI compatible endpoint and a single key reach models from OpenAI, Anthropic, Google, DeepSeek, Qwen and other providers; switching models is a one word change in your request. If a provider has an outage or rate limits you, traffic moves to a healthy route automatically, so your app keeps answering. It also works inside Claude Code, Cline and most AI chat clients. The project is open source, chats stay local in the browser, and billing is a free tier followed by pay as you go with no monthly plan.
