Live

A dozen everyday developer tools: JSON, JWT, YAML, Base64, UUID, Regex, hashing, Markdown, Timestamp, Cron, and more. Everything runs locally in your browser — open and use, your input never leaves your device.

Principles

Runs locallyAll computation happens in the browser — open and use.
No backendNo server dependency: nothing to upload, nothing to go down.
Data stays on your deviceWhat you type never leaves your machine.
