🎉 Hey Product Hunt! I’m excited to share API Sniffer Pro with you! I built this tool because debugging APIs was always painful — switching tabs, digging through DevTools, copying payloads manually, or trying to document endpoints after development was endless busywork. API Sniffer Pro was created to solve that. It lets you capture and inspect all API requests in real time, view headers/payloads instantly, export logs, and even generate API documentation and code snippets automatically. My goal is simple: Make the API debugging and documentation workflow effortless for developers and testers. I'd love your feedback, suggestions, and feature requests. Thank you for checking it out and supporting the launch! 🚀

Thanks everyone for checking out API Sniffer Pro! 🙌

A quick note about the latest update:

We added domain-based monitoring, so you can configure one or multiple domains once, and the extension automatically tracks all API calls from those sites. No switching, no clutter — just clean and focused debugging.

If you try it out, I’d really love to hear:

• Does domain-based tracking make your workflow easier?

• Any domains or use-cases where you want more customization?

• Features you'd like to see next?

Your feedback will help shape the next update. Thank you again for the support! 🚀
