Maker
📌
Hey Product Hunt 👋
I’m Manoj, the maker of Dev Utility Toolkit.
As a developer, I kept jumping between multiple tools just to handle simple tasks like formatting JSON, decoding JWTs, encoding URLs, or comparing text. It was slow, cluttered, and sometimes risky when working with sensitive data.
So I built a fast, minimal, privacy-first toolkit where everything works instantly in your browser — no login, no tracking, no server calls.
