Hi Product Hunt! I'm the creator of CodeKivo. Like many of you, I format JSON payloads, inspect SQL queries, decode JWTs, and test regex expressions every single day. But over time, I grew frustrated with existing tool sites. Many are covered in intrusive banner and popup ads, and pasting sensitive production payloads or tokens into unknown backend servers always felt risky. I built CodeKivo with a simple core philosophy: Zero Data Egress. Everything runs 100% client-side inside your browser's local memory. Your code and data never leave your machine. I also built it with Astro and React islands to keep pages lightweight and instant without unnecessary bloat. CodeKivo is completely free to use with no account or sign-up required. I would love to hear your thoughts, bug reports, and what daily developer utilities you would love to see added next! Thank you for checking it out!
