Stop typing. Start speaking. 4x faster.

Hey Product Hunt! 👋 I'm Arga, a developer from Indonesia. I built Free API Hub because I was tired of switching between docs and API testing tools just to try a simple endpoint. Free API Hub is a free, open-source playground where you can: • Browse 224 free public APIs across 35 categories • Test any endpoint with the built-in panel (GET/POST/PUT/DELETE) • Use AI to discover the perfect API for your project • Real-time health monitoring for every API • Smart response viewer — JSON, images, video, audio, CSV, HTML, XML • Install as a PWA on any device Everything runs in the browser — no signup, no API keys, no backend needed. Just open and explore. I'd love to hear your feedback! What categories or APIs would you like to see added? Also, the project is completely open source — contributions and PRs are welcome! 🎉
