UnoRouter

For developers and AI app builders who are tired of keeping a separate account, key and bill for every model provider. UnoRouter is an open source LLM gateway with an OpenAI compatible API: change the base URL in your existing SDK, Claude Code, Cline or SillyTavern, and one key reaches models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and others. What makes it different: requests are routed to a healthy provider and fail over automatically when one goes down, the whole stack is open source, and the built in chat keeps conversations in your browser. Free tier to start, then pay as you go without a subscription.
