About Kitsy AI

Kitsy AI is a free collection of 57+ online developer utilities — formatters, converters, encoders, generators and more — designed to be fast, beautiful, and respectful of your privacy.

Privacy first

Every tool runs entirely in your browser. Your data is never uploaded to a server, logged, or shared. There is no tracking and no account required. That makes these tools safe to use even with sensitive input like tokens, credentials, or proprietary code.

Built for developers

Whether you need to format JSON, decode a JWT, work with Base64, or test a regular expression, the goal is the same: a clean, instant, no-friction experience.

Free, always

All tools are free to use with no limits and no sign-up. Browse the full tool collection or read our in-depth guides and tutorials.
