Hey everyone, I built this open source alternative to OpenRouter and LiteLLM, but it lets your users use their own OpenAI, Anthropic, and Gemini API keys for your application. This way, if people want to use your application, you don't have to use your own credits; they can use their own keys instead.
I imagine this to be especially useful for people who are building frontend-only applications, especially people who are building on top of Replit, Lovable, and Emergent. Because AI providers don't allow direct API calls from browser frontends, and byok-relay provides you a managed service for AI API calls without having a backend.
I would really appreciate your feedback.
Alternatively, if you are short on time, you could just star my repository or upvote my launch.
