CodeUtilityKit is a free collection of browser-based developer tools for everyday coding, formatting, conversion, debugging, and productivity tasks. It includes tools like JSON Formatter, JWT Decoder, Base64 Encoder/Decoder, SHA256 Generator, CSV to JSON, JSON to CSV, Password Generator, UUID Generator, Regex Tester, QR Code Generator, Timestamp Converter, and many more. Everything runs locally in your browser, so your code, tokens, API keys, passwords, and files stay on your device.

Hey Product Hunt 👋 I’m excited to launch CodeUtilityKit — a free collection of 100+ developer tools that run directly in your browser. As developers, we often need quick utilities like JSON formatting, JWT decoding, Base64 encoding, CSV conversion, hash generation, UUID generation, regex testing, password generation, and timestamp conversion. The problem is that many tools are either cluttered, slow, require sign-up, or make you wonder where your data is going. CodeUtilityKit was built to solve that. The goal is simple: give developers a clean, fast, privacy-first toolbox for everyday tasks. All tools run locally in the browser, so your data never needs to be uploaded to a server. What you can do with it: Format, validate, and convert JSON Convert CSV to JSON and JSON to CSV Decode JWT tokens Encode/decode Base64, URL, and HTML Generate SHA hashes, UUIDs, passwords, QR codes, and API keys Test regex patterns Work with timestamps, colors, text, PDFs, and more It’s completely free, requires no login, and is built to stay lightweight and distraction-free. I’d love your feedback on which tools you find most useful and what I should add next. Thanks for checking it out 🙌

The privacy-first approach is a smart move for tools like JWT and Base64 decoders where people paste sensitive tokens. Running everything client-side removes that "should I trust this site" hesitation that usually comes with random dev utilities.

Love that everything runs locally in the browser, no uploads needed for sensitive stuff like JWTs and API keys. The collection hits all the everyday utilities without any clutter.
