Building on several model vendors usually means several keys, SDKs and invoices. UnoRouter collapses that into one OpenAI compatible endpoint: keep your current client, set a new base URL and pick models from OpenAI, Anthropic, Google, DeepSeek, Qwen and others by name. Failed upstream calls are retried on another healthy provider. The project is open source, the chat keeps history in your browser, and pricing starts free and then follows usage.
