PureDevUtils is a free collection of 16 browser-based developer tools: JSON formatting, validation, minifying, and diffing; JWT decoding; Base64 and URL encoding/decoding; JSON to CSV/YAML/ TypeScript/Python/Java conversion; and UUID generation. Every tool runs entirely client-side, so nothing you paste or generate is ever uploaded to a server. No sign-up, no ads โ just fast, private utilities for developers.

PureDevUtils provides a collection of browser-based developer utilities with a privacy-first approach. Tools process data locally in the browser, so users can format, validate, encode, decode, and convert data without uploading it to a server.
PureDevUtils is free, requires no sign-up, has no ads, and focuses on client-side processing. It brings common developer utilities together in one simple interface while keeping user data in the browser.
PureDevUtils is designed for web developers, software engineers, students, API developers, QA engineers, and anyone who regularly works with JSON, JWT, Base64, URLs, UUIDs, CSV, YAML, and other developer data formats.
PureDevUtils was created to make everyday developer tasks faster and more private. Instead of relying on multiple online utilities or uploading potentially sensitive data to third-party services, PureDevUtils brings useful tools together in one browser-based platform with client-side processing.
PureDevUtils is built with TypeScript and Next.js, with JavaScript for supporting functionality. The project uses Vitest for testing and runs as a browser-based web application.
