About DevBench

DevBench is an all-in-one developer toolkit that runs entirely in your browser. Format JSON, encode data, compare text, debug JWTs, test HTTP APIs, edit cron expressions, beautify code, and use dozens of smaller converters — without signing up and without sending your payloads to our servers.

We focus on speed and privacy: heavy work stays on your machine, using Web Crypto and modern JS where needed.
