Hey Product Hunt! 👋 I'm thrilled to launch API-LLM-Hub, born from countless frustrating nights battling API integration issues. This vanilla JS library simplifies LLM API usage for static sites (like GitHub pages), supporting OpenAI, Anthropic, TogetherAI, and Google's Gemini - all without a backend! Key features: Browser-based (no server-side code), implements Anthropic's developer CORS solution (one of the few examples I could find now), multi-provider support, and pure vanilla JS (no build steps). I'd love to hear your thoughts! Have you faced similar challenges? How might this tool fit into your projects?
