35 private developer tools that run in your browser
About DevSexy
DevSexy is a collection of thirty-five developer utilities for working with JSON, JWTs, certificates, text, code and structured data. It is aimed at engineers who want quick, focused tools for everyday debugging and formatting without sending their input anywhere.
Everything runs locally in the browser, so pasted data never leaves the device and no account is needed. The tools cover tasks such as formatting and validating JSON, decoding and signing tokens, comparing text line by line or character by character, and converting HTML or SVG into React components.
The product is also available as a Mac app with keyboard shortcuts for repeated work, and it keeps working offline. Its pitch is a polished, calm interface that stays out of the way while handling precise technical tasks.
