👋 Hey Product Hunters! I'm super excited (and a little nervous) to share X-CURL with you all. This project started because I kept hitting CORS issues and needed more flexibility when calling APIs from the frontend — especially when I couldn’t touch the backend. So I built X-CURL: a tool that lets you control headers, payloads, and even response manipulation through custom Lua scripts, all wrapped inside a single shareable URL. You can even use it directly in HTML tag attributes! If you’ve ever wished you could just "fix it from the frontend," I hope this helps. Would love your thoughts, feedback, or any wild use cases you can think of 💡 Thanks for checking it out!
