👋 Hi Product Hunt! I'm thrilled to introduce Birhrt Dev Tools today. As developers, we constantly need quick utilities — formatting JSON, decoding JWTs, generating hashes, or tweaking PDFs. But the existing tools often have three major problems: Privacy risks (pasting sensitive API keys or client data into random servers). Intrusive ads and paywalls. Mandatory sign-ups. I built Birhrt Dev Tools to fix exactly this. It’s a unified suite of 26+ developer utilities designed with a privacy-first architecture. 🔒 How it works: Every single tool runs 100% locally in your browser using standard Web APIs. Whether you are manipulating a PDF or formatting a 5MB JSON file, your data never touches a server. 🚀 What's inside: Data: JSON Formatter, JSON/YAML/CSV converters. Security: JWT Decoder, Base64 Encoder, Hash Generator (MD5, SHA-256, etc.). Documents: PDF Organizer, PDF Redactor, Image to PDF. Code: Regex Tester, SQL Formatter, Cron Expression Generator. Utilities: Image Compressor, QR Code Generator, UUID Generator. It is completely free, requires no account, and has no usage limits. We've also just launched our Developer Blog with deep dives into topics like JSON internals and JWT auth. I'd love for you to try it out. What is your most frequently used dev tool? Let me know in the comments, and I might just build it next! Happy coding! 👨‍💻
