About Utilsy
Utilsy is a set of browser-based developer tools for everyday tasks like formatting JSON, decoding tokens, generating UUIDs, and building cron expressions without extra friction.
What is Utilsy
Utilsy is a collection of fast, minimal, and privacy-focused developer tools designed to run entirely in your browser. It helps developers work with JSON, Base64, JWTs, UUIDs, and cron expressions without unnecessary complexity.
