UnoRouter

UnoRouter is an LLM gateway for developers that routes requests across every major AI provider with one key and automatic failover. It speaks the OpenAI API, so existing apps, agents and chat clients switch over by changing the base URL.

Overview

What is UnoRouter?

UnoRouter sits between your app and the model providers. You send OpenAI style requests to one endpoint with one key, name any model from OpenAI, Anthropic, Google, DeepSeek, Qwen and others, and the router picks a healthy provider. If one fails or rate limits, the call is retried elsewhere, so an outage at a single vendor does not break your product.

How to use UnoRouter?

Users create an API key to access models through an OpenAI-compatible endpoint, or use the built-in chat without an account.

UnoRouter 's Use Cases

Developers can connect apps and coding agents to AI models. Users can also chat with characters or connect compatible chat clients.
