UnoRouter

UnoRouter is a free-to-start AI gateway for developers and hobbyists who want to test models without signing up at every lab. Create an account, copy one key and you can call free models right away; the same key later unlocks paid models from OpenAI, Anthropic, Google, Meta, DeepSeek, Qwen and Mistral. The API follows the OpenAI format, so it plugs into the OpenAI SDK, Claude Code, Cline, OpenCode and most other OpenAI compatible tools by changing the base URL. Smart routing picks a healthy provider for every request and switches automatically when one fails, which keeps scripts and agents running through outages. The project is open source, and the web chat is local-first: your conversations are kept in your own browser. There is no subscription; after the free tier you top up credit and pay only for what you use.
