UnoRouter

Open-source LLM gateway with one key for every major model

AILaunched Nov 2026

The story

UnoRouter is an open-source alternative to proprietary LLM routers. Instead of separate accounts and keys for OpenAI, Anthropic and Google, you get one OpenAI-compatible key that reaches every major model. It drops into existing code, Claude Code, Cline or any chat client by changing the base URL. When a provider has an outage, requests fail over to another one automatically. The whole stack is public, and the chat stores history in your browser rather than on a server. Free tier with free models, then pay as you go, no subscription.

Overview

UnoRouter is an LLM gateway for developers and AI hobbyists who want to reach many model providers without managing a separate account for each. It exposes one OpenAI-compatible endpoint and one key. Requests are routed to a healthy provider, with automatic failover when one goes down. A free tier includes free models; paid usage is pay as you go.
