About

DevUtilities.dev is a lightweight toolbox for everyday development tasks — formatting JSON, comparing payloads, decoding JWTs, working with Base64, testing regex patterns and building cron expressions.

Built for engineers who open the same utilities dozens of times a day and want them to be fast, predictable and in one place — without ads, pop-ups or account creation.

Mission

Remove small but constant friction from backend and frontend development. DevUtilities.dev gives you a stable set of utilities with a consistent interface and keyboard-friendly workflow.

What you can do here

• JSON Formatter & Diff: validate, beautify, minify and compare JSON structures when debugging APIs and configuration files.
• JWT Decoder & Base64: inspect token headers and payloads, convert text to and from Base64.
• UUID, Regex & Cron: generate IDs, design and test regular expressions, build human-readable cron schedules.

Privacy & data handling

Almost all tools run entirely in your browser. Input data such as JSON, tokens and text is processed client-side and is never sent to a server.

Who uses DevUtilities.dev

Backend engineers, frontend engineers, SRE/DevOps and QA teams who work with JSON APIs, logs, configuration files and automation scripts. These tools are meant to sit in your bookmarks bar.
