What is Utilly?
Utilly is a collection of online developer utilities designed to make your workflow faster and more efficient. Whether you need to format JSON, decode JWTs, generate UUIDs, or convert between color formats - we've got you covered.
Unlike other online tools that send your data to servers, Utilly processes everything locally in your browser. This means your sensitive data (API keys, passwords, tokens) never leaves your machine. Perfect for working with production data without security concerns.
Built with vanilla HTML, CSS, and JavaScript. No frameworks, no build steps required (except for deployment), and no tracking. Just pure, privacy-focused utility.
