Seeking Feedback: I built a suite of 100% client-side, privacy-first developer utilities!

by•
Hey everyone, I recently launched Secure Devutils ( https://securedevutils.com/ ) —a collection of free, privacy-first web utilities for developers. Why Secure Devutils? I noticed many online JSON formatters and string converters send sensitive payloads to backend servers. I wanted a safer alternative, so I built this entirely with client-side Web Workers and offline PWA support. Current Features It currently includes: • JSON formatters • JWT decoders • Hash generators • Base64 tools • And more. Most importantly, your data never leaves your browser. Seeking Feedback I would love to get your honest feedback! • Are there specific tools you feel are missing? • How is the UI/UX? • Have you noticed any bugs or performance issues? Thanks in advance for reviewing it and providing your suggestions!

Wow, this looks really handy! I love the client‑side approach for privacy‑first tools... The UI feels clean and the performance smooth. It’d be great to see a YAML formatter or a diff tool added. If you're up for it, I'm launching on PH soon — would appreciate a follow (See PRODUCT HUNT LAUNCH Link in my profile).

@rianbrob Hi Rian, Thank you so much for taking the time to review my website and for the helpful suggestions! I really appreciate the feedback and support. I checked out The Sponge, and it is a brilliant concept. Using an AI browser extension to instantly turn reading into spaced-repetition flashcards is incredibly useful for lifelong learners. If you are open to a small idea, adding a quick, looping GIF in the hero section of your landing page that shows the extension instantly "soaking up" page text into a flashcard would be a fantastic way to visually grab users and show them the "aha" moment right away. The app looks incredibly solid, and I am wishing you huge success with your launch!
