Keep AI features online with one key and automatic provider failover

UnoRouter is a failover-first LLM gateway for indie startups that cannot afford an AI feature going dark when one provider has an outage. Your app calls a single OpenAI-compatible endpoint with one key; behind it, models from OpenAI, Anthropic, Google, Meta, DeepSeek, Qwen and Mistral are routed to whichever provider is healthy.
The same key works in backend code, Claude Code, Cline, OpenCode and other OpenAI compatible clients. Free models help during prototyping, the web chat stays local-first in the browser, and the project is open source. Billing: free tier, then pay-as-you-go, no subscription.
Early products change models often and rarely have time for several vendor integrations. One endpoint, free models to start and pay-as-you-go pricing keep the cost and the code small until the product finds its fit.
