What UnoRouter is
UnoRouter is a gateway for large language models. You sign up once, create one API key and send OpenAI style requests to a single base URL. The model field decides where the request goes, whether that is a GPT, Claude, Gemini, DeepSeek, Qwen or GLM model.
Why it exists
Juggling a separate account, key, SDK and monthly bill for every lab gets old fast, especially when you only want to compare two models on the same prompt. UnoRouter puts them behind one endpoint and one balance.
How it behaves
- Automatic failover: when a provider is slow or out of capacity, the request moves to another healthy provider for the same model.
- Streaming and tool calls stay in the OpenAI format, so the official SDKs, Cline, Aider and Claude Code work after changing the base URL.
- Every model page shows its price and whether the provider may retain or train on inputs.
Pricing
A free tier with rate limited free models, no card needed. Paid models are pay as you go from prepaid credit that never expires, with no subscription.
Open source
The whole stack is public on GitHub, and the web chat keeps conversations in your browser instead of on our servers.
