Hey everyone, I built FreeAPI because I was tired of the exact same loop every time I started a side project: digging through massive GitHub lists, finding out half the links are dead, getting hit with surprise paywalls, or running into CORS issues in the browser console before I could even test a simple endpoint. FreeAPI brings together over 500 verified free APIs across dozens of categories. You can test them directly from your browser through our sandbox without fighting CORS, and there are 11 edge utilities built in (JSON formatter, Base64, regex, UUID generator, etc.) that run 100% locally in your browser. Nothing touches our server and there are zero ads. The entire site is statically generated with Next.js so it loads pretty much instantly. I'd really appreciate your honest thoughts on the UI, the latency, and what tools or APIs you feel are missing. Drop any feedback below and I'll be here answering questions all day. Thanks for checking it out!
