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 🙌
