UnoRouter

UnoRouter is a unified, OpenAI-compatible LLM gateway that lets you connect to 260+ AI models through a single API key. Build apps and run agents without changing your client each time you switch models or providers—use the same key for coding workflows and chat experiences.

Beyond the API, UnoRouter includes a built-in chat client. Open the chat in your browser to talk with character personas, using free models wired in on the backend so you can start quickly without setup or a key. You can also import SillyTavern cards and run full roleplay features like lorebooks and group chat.

Designed for practical use across tools, UnoRouter works with coding agents, roleplay frontends, desktop/web chat clients, and CLI tools via fully OpenAI-compatible endpoints. Automatic provider failover and multi-protocol support help keep your requests flowing as you scale.

Does UnoRouter use an OpenAI-compatible endpoint and request format?

Yes—UnoRouter exposes fully OpenAI-compatible endpoints (for example, /v1/chat/completions) so you can use standard OpenAI-style requests with your single API key.

How many models can I access through UnoRouter with one key?

UnoRouter connects you to 260+ AI models through one API key.

Can I use UnoRouter with coding agents and terminal/CLI tools?

Yes. UnoRouter supports coding agents and CLI tools, working as a custom OpenAI-compatible API across those clients.

Is there a built-in chat option without using my own API key?

Yes. You can open the built-in chat in your browser and use free models that are already wired in, with no signup, key, or setup required to start chatting.

Do UnoRouter chats stay private?

Conversations live in your browser and aren’t stored on UnoRouter’s server for reading, so they remain private.

Can I import SillyTavern cards for roleplay characters?

Yes. SillyTavern card import is built in for the character chat experience.
